Ignition marks for VAZ 2104 injector – Set the ignition on the VAZ 2104 carburetor

How to set the ignition on a VAZ 2107? Carburetor.

If you have recently purchased a VAZ 2107, which has a carburetor power system, then we advise you to immediately start monitoring its condition.
This is necessary so that if any changes occur in its operation, you can make the required repairs in a timely manner. If you notice that your car's fuel consumption has increased, and the engine is constantly malfunctioning, then it's time to start tuning the ignition. In this article we will tell you how to set the ignition on a VAZ 2107 carburetor.

About installing the ignition switch

The ignition switch is also part of the engine ignition system design. Sometimes the contact group or mechanical part wears out. It would not be amiss to consider how to install the ignition switch on a VAZ-2106.

Before installing the element, it must be removed. To do this, disconnect the negative terminal from the battery, then remove the decorative trims on the steering column. Next, it is important to sketch or write down where the wires are connected. After this, use a Phillips screwdriver to unscrew the lower fasteners of the ignition switch. Next, insert the key into the lock and turn it to the zero position to disable the steering wheel locking mechanism. With a thin awl, press the latch, due to which the lock can be held in place. If you pull the key, the lock can be removed.

After the lock mechanism is removed, a new lock is installed in the same manner in the reverse order.

Setting the ignition timing with advance

This setup is completely easy to do. Even a beginner can cope with this task. To do this, prepare a 13 mm wrench and a special 38 mm crankshaft wrench in advance. If your car is running, be sure to turn off the engine, since you can only turn on the ignition when the engine is turned off. First, the piston of the first cylinder is installed at the top dead center of the compression stroke, that is, in the ignition position. Before doing this, remove the candles and plug their holes with cotton wool or some other material. You need to align the mark on the crankshaft and the front engine cover. To do this, use a wrench to start turning the crankshaft clockwise. During this action, the air compressed there should push out the cotton wool, thereby indicating the compression stroke. Continue turning the shaft slowly until the marks on the timing belt pulley and cover line up.

Please note that there are 3 marks on the cover:

• The first indicates ignition advance by 10º;
• the second – by 5 º;
• the third is equal to zero.

Since a VAZ 2107 engine with a carburetor runs on 92 or 95 gasoline, we need to set the ignition for these types of fuel. That is why you should select the second mark, which will indicate an ignition advance of 5º. Once the required parameters match, put the spark plugs in place and remove the wires. The system is ready for use.

Instructions for installing the ignition

Let's see how to install electronic ignition on a VAZ-2106. In fact, the installation process is not complicated, but it requires a certain amount of time and attention.

The crankshaft is turned with a wrench or any convenient tool until the mark on the pulley aligns with the mark on the engine block. When the marks align, the first or fourth cylinder of the engine will be at top dead center. This can be checked by unscrewing the spark plugs and removing the cover from the ignition distributor. The slider inside the distributor will be turned towards the first or fourth cylinder. The easiest way to navigate is by the cover.

Then remove the vacuum tube from the fitting on the UOZ vacuum regulator, pull out the wires from the distributor cap and unscrew the nut holding the distributor. Then the distributor is removed, but first you need to remember or sketch how the slider is positioned. In the process of removing the distributor, it is important to ensure that the gasket that is installed between the block and the distributor does not go away - it will still be needed.

Next, take a new distributor from the contactless ignition kit and put a gasket on it. Then the shaft is turned so that the slider is installed in the same position as on the old distributor. Then you need to install the distributor on the block and tighten the fastening nut a little. After this, put on the distributor cap and connect the wires to the spark plugs. Don't forget about the vacuum tube.

Next, the ignition coil is dismantled, and a new one from the kit is installed in its place. The main thing here is not to confuse the wires that were connected to this very coil. Sometimes you can connect the wrong wire to the positive terminal. Then the switch is installed. In more recent cars of recent years there is a special place for it near the distributor. On older models, you will have to make holes to mount the switch.

When you know how to install the VAZ-2106 electronic ignition yourself, all that remains is to learn how to regulate the OZ.

Adjusting the ignition timing

For subsequent actions, use a 13 key to loosen the fastening nut of the distributor (ignition distributor). Connect one wire from the light bulb (it will act as a voltmeter, that is, indicate the presence of voltage) to the low-voltage terminal that the coil has, the second to ground. Now turn on the ignition. Slowly and carefully rotate the distributor body clockwise, stopping immediately when the light goes out. The sparks that appear will indicate the moment of ignition. Move the distributor counterclockwise until the contacts are disconnected and the lamp lights up again. Everything is in order, you can safely tighten the distributor, the setup is complete.

Installation of electronic ignition

Electronic ignition makes engine operation smoother and softer, makes it easier to start in the winter, and reduces fuel consumption. If you, having a carburetor engine, decide to switch to contactless (electronic) ignition, we will tell you how to install it correctly on a VAZ 2107 car. An electronic system for a car with a carburetor should not be too expensive or cheap. It is best to opt for a product in the mid-price category, so that later you don’t have to change anything after a while. Before work, prepare a drill and a set of keys. For an overview, first read the included instructions carefully and open the carburetor type engine kit. It includes:

• ignition coil;
• distributor;
• switch;
• 4 candles;
• connecting and high-voltage wires.

The system is easy to install. First of all, remove the negative terminal from the battery and turn the crankshaft until marks numbered 3 and 4 align, that is, the highest dead center.

Now you can begin the main steps. The coil should be disconnected from all wires, remove it and install a new one. The coil can now be connected to the central high voltage wire. Connect 2 brown wires to contact “K”, and 2 blue wires to contact “B”. Now remove the distributor cover. Please note that the slider must be set exactly as shown in the picture. Mark this place with a marker on the block to correctly install the new distributor. Now you can unscrew this part and put it to the side. After opening the cover of the new distributor, place the slider perpendicular to the engine and insert it into the hole in the cylinder block. Align it with the mark on the block. Next, put on the cover and connect the wires. Decide where the switch will be located, since there is no space for it in the VAZ 2107 car. We recommend installing it next to the washer reservoir. Secure it with self-tapping screws and install the connector. Don't forget the candles. To replace them on a VAZ 2107 car, you will need a spark plug wrench, which you should use to unscrew the old spark plugs from the cylinders and put new ones in place. Their color can say a lot about the engine's performance, so if the spark plugs have black carbon deposits, the air filter should be replaced. Normally, candles should have a light brown color.

Detailed guide to setting up the ignition

Motorists have long been convinced of the advantages, which are devoid of the disadvantages of a contact one, for example, there is no need to adjust the gap in the contact group. In this article we will look at how to adjust 2106 for the 1st cylinder.

There are marks and castings on the cylinder head cover and crankshaft pulley.

Using the marks you can adjust the ignition timing:

• the first mark, located clockwise, means that the ignition timing is 10°;
• the middle mark is designed to set the lead angle to 5°;
• the shortest, last mark sets the advance angle to 0°: in this case, the mixture will ignite when the piston reaches top dead center.

The marks are aligned by rotating the crankshaft, either by a ratchet, or by using a special wrench on the nut.

Tools and materials

In order to adjust the ignition on a VAZ 2106, you need to prepare the following tools:

• key for unscrewing spark plugs;
• special key for rotating the crankshaft;
• key to "13";
• control device: 12 V indicator light or voltmeter.

You can also expose using a stroboscope.

Stages

The ignition is set step by step:

We have set the ignition, now we need to check whether the setting is correct by following these steps:

1. The check can be performed while the machine is moving. First you should warm up the engine and then accelerate it to a speed of 40-50 km/h. Upon reaching this speed, switch to fourth speed and drive for some distance without accelerating.
2. Then you need to sharply press the gas pedal. 2-3 seconds after this, detonation and sounds resembling finger snapping should appear. The sounds should stop as the vehicle accelerates after approximately 5 km.
3. If detonation does not occur, it is necessary to adjust the position of the distributor. The reason may be “early” ignition. If detonation does not occur, then the reason may be “late” ignition. If “early”, you need to turn the distributor to the right one degree. When “late” - one degree to the left. The procedure should be performed until detonation lasts 1-1.5 seconds.
4. Having completed the adjustment, you need to put a dash on the distributor with paint showing the position of the mark with an average length in relation to the cylinder block.
5. Next, you need to install the distributor correctly. First, you should again use the unscrewed spark plug and close the hole with your finger to set the first cylinder to TDC.
6. Next, you need to align the mark on the crankshaft with the mark on the timing cover. To do this, turn the crankshaft clockwise.
7. After removing the cover from the distributor, you need to install the slider. Its position should coincide with the imaginary straight line from the contact on the cover of the first cylinder.
8. After all the steps, we put the distributor housing in place. This completes the ignition setup on the VAZ 2106.

There are main symptoms by which one can judge that it is necessary to set the ignition on the VAZ 2106:

1. Fuel consumption is too high. With late ignition, the dynamics of the car decreases. In order for the car to accelerate as before, it needs more fuel-air mixture.
2. Dynamics is lost: with late ignition, the mixture ignites after the piston has already moved down due to the inertia of the flywheel.
3. Popping sounds in the muffler. In this case, the explosion follows, and it takes some time for the gases to expand. When the piston reaches bottom dead center, the next stroke will be the exhaust stroke. In this case, part of the fuel explosion will escape into the exhaust pipe, which is the cause of the popping noise.
4. Increased engine noise. If the engine noticeably rattles or detonates, you need to turn on the ignition. In this case, the piston only goes up, and the ignition goes towards it. This makes the engine run rough with unpleasant sounds when running.

While operating a VAZ 2106 car, the car owner may encounter difficulty starting the engine and interruptions in the operation of the power unit. The cause of such malfunctions is incorrectly set ignition timing, which requires timely adjustment. This kind of work is not particularly difficult, so even those car owners who have little idea about repairing their car can handle it. In this article we will tell you how to set the ignition on a VAZ 2106.

Apr 15, 2021 VAZ 2101, VAZ 2102, VAZ 2105, VAZ 2106, VAZ 2107, Zhiguli, Classics by admin

Today, many owners of Classics (VAZ-2101, VAZ-2102, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107) contactless electronic ignition on their cars . And this is natural. The advantages of contactless ignition are obvious and tested in practice. For example: ease of installation and configuration, reliability and accuracy of operation, significant improvement in engine starting in the cold season. It seems to me that the list of “pluses” is not bad!? And if you are not a conservative, you are quite tired of the “quirks” of the contact pair and for certain reasons, you have not yet decided to buy a contactless ignition kit, then this article (I hope) will help you take the last step. Since, in fact, you should not encounter any major difficulties and problems when installing the “new thing”. For example, it seems to me that the biggest problem is the purchase of the kit itself. After all, you have to force yourself to part with a tidy sum ;)))

Now from the introduction, let's move on to the main thing. contactless electronic ignition kit on your favorite and invincible Classic (VAZ-2101, VAZ-2102, VAZ-2104, VAZ-2105, VAZ-2106, VAZ-2107) .

Selection and purchase: I can personally recommend choosing a contactless ignition kit made in Russia in the city of Stary Oskol - look at photo 1. In the box we find a coil, a switch, a distributor and a wiring harness (photo 2). In terms of quality, this kit is considered one of the best. The truth is that the price “bites”))) Also, look at what engine block you have, since distributors come in two types (they differ in the length of the shaft) - for the VAZ -2101, VAZ-2102, VAZ-2104, VAZ- 2105 and VAZ-2103, VAZ-2106, VAZ-2107 .

We are preparing for installation - a drill, a drill and a pair of self-tapping screws (for the coil in the engine compartment there is a standard mounting location, but the switch will have to be mounted independently), an open-end wrench for 13, ring or socket wrenches for 8 and 10. In order to install the engine on For the “TDC” mark, you will need a 38 key.

We can start replacing:

We take a 38mm wrench and turn the ratchet nut until the marks on the crankshaft pulley and the front engine cover match, that is, we set the engine to the “TDC” mark (photo 3).

We remember the location of the distributor and the slider; the new distributor will be placed in this position. In my case, the slider is turned towards the valve cover and “stands on the fourth cylinder” along the distributor cover (photo 4). This is his correct position.

Also, we find the B+ mark on the coil and remember which wires are screwed to it (photo 5). Then unscrew and remove the coil.

Using a 13mm wrench, unscrew the distributor lock nut and remove it. We try not to lose the gasket - photo 6.

We fix the switch, screw the black wire to ground (photo 7). We install and secure the coil to the body. We connect standard wires to the corresponding terminals (pay attention to the location of terminals B and K on the new coil - photo 8). Wires from the switch - labeled + to terminal B, the second wire to terminal K - photo 9.

We install the distributor, but do not tighten the lock nut completely. We connect the wires from the switch to the distributor (photo 10). We check the position of the distributor and slider (photo 11), put on the cover and connect the wires in the order 1-3-4-2 (photo 12).

After everything has been secured, we can start the engine and begin adjusting the ignition “by ear.” But if you have a strobe, you can use it))). To do this, with the engine running, slowly turn the distributor (the lock nut, we didn’t tighten it for this) “back and forth” (photo 13) and look for the middle position in which the engine speed will be the highest and most even.

We set and adjust the ignition timing of the VAZ 2105

The VAZ 2105 engine was installed on the model of the same name, and in addition, on bodies 2107, 2104 and on some export versions of Zhiguli in older bodies. It differed from the old 1.1 or 1.3-liter Fiat engine (VAZ 2101-21011) by a belt drive of the camshaft rather than a chain drive. Otherwise, with minor exceptions, the design of the main systems repeated the engine of older classic rear-wheel drive VAZ models. Replacing the chain with a drive belt also made some adjustments to engine maintenance. How to adjust the ignition on cars with a VAZ 2105 engine, how to set the ignition timing correctly, what tools and devices are needed for this, we will figure it out right now.

Ignition VAZ 2105: signs of malfunction, device

Initially, VAZ 2105 cars from 1980 had a classic contact ignition system installed until 1989. Later it was replaced with a contactless one, but the principle of operation of the system remained the same. The stability of the system affects not only the starting, efficiency and power of the engine, but also the nature of its operation. Incorrectly set or disabled ignition, more precisely, the moment of spark formation in the combustion chamber, can lead to engine detonation, and this is a direct threat of destruction of both the cylinder-piston group and other elements of the power unit.

Schematic diagram of the VAZ 2105 contact type ignition system

The ignition of the VAZ 2105 consists of basic elements, each of which is subject to its own problems:

1. Distributor, breaker-distributor (2) . In any ignition system, it performs the function of not only distributing voltage between the cylinder spark plugs in a certain sequence (1-3-4-2), but is also responsible for the timely supply of an impulse to the ignition coil using contact group 4 , which in turn generates a high current voltage to form a spark at the spark plug electrodes.
2. Ignition coil (5 ). VAZ 2105 cars use an oil-filled open-type coil B-117 . Its task is to convert 12 V current into high voltage current (about 12-24 kV) according to a signal from the switch 6 .
3. Switch 6 is a semiconductor circuit board for controlling the ignition system. After supplying a control pulse from the ignition relay 7 , the switch closes the circuit of the secondary winding of coil 5, activating the step-up transformer.
4. The system is activated using the ignition switch contact group 8 .

Terminology

Ignition distributor

- an electromechanical device that ensures timely supply of high voltage pulses to the spark plugs.
It is often called a distributor
.

Ignition advance

- ignition of the working mixture in the cylinder before the compression stroke ends.

Ignition timing (IDA)

— the angle of rotation of the engine crankshaft from the position corresponding to the appearance of a spark on the spark plug until the piston reaches top dead center.

Contact ignition system

- a system in which switching of the ignition coil is provided by a mechanical interrupter.

Contactless ignition system

- a system in which switching of the ignition coil is provided by an electronic module controlled by an electronic crankshaft position sensor - for example, a Hall sensor (VAZ-2108) or magnetoelectric (GAZ-2410).

Breaker

ignition system - a mechanical switch in the distributor, directly connected to the primary circuit of the ignition coil.

Runner

- a distributor element that alternately transmits high voltage from the ignition coil to high-voltage wires connected to the engine spark plugs.

Angle of closed state of contacts (UZSK)

- a value indicating how long the contacts of a mechanical breaker should remain closed. For classic Zhiguli cars, the UZSK is approximately 55 degrees. A correctly selected UZSK gives the ignition coil the opportunity to gain the necessary energy and completely transfer it to the spark plugs.

Adjustment data and ignition ratings for VAZ 2105

To adjust the ignition system, it is imperative to know several parameters that relate to the settings and nominal factory values ​​for system elements and their interaction:

1. For the contactless ignition system, spark plugs A17DV-10 or their analogues are used. The gap between the spark plug electrodes should be within 0.8 mm , and for A17DV spark plugs (for contact ignition) the gap is 0.6 mm .

   
   Standard spark plug VAZ 2105

2. Brands of switches for ignition VAZ 2105 - 3620.3734, HIM-52, VAT10.2 or PZE4020. The commutator must supply a pulse to the coil within 9 Amp.

   
   

3. Distributor for contact ignition system brand 30.3706, gap between contacts with completely open plates is from 0.35 to 0.45 mm , adjustable using a feeler gauge. For contactless ignition of the VAZ 2105, a 37/38.3706 distributor is used, which does not require gap adjustment.

4. The ignition timing on VAZ 2105 engines is 3-5 degrees .

Knowing these ratings and adjustment data, we can easily set up the ignition system of the VAZ 2105 and set the ignition timing accurately and quickly. To make adjustments, we will need either a strobe light or a 12 V test lamp, or we can do without them and set the ignition according to the marks on the front crankshaft cover and the crankshaft pulley.

Step-by-step instruction

To install electronic ignition, proceed as follows.

1. Turn the crankshaft with a crank or wrench until the mark on the shaft pulley aligns with the long mark on the cylinder block. When these marks are aligned in the first or fourth cylinder, the piston is in the TDC position. This can be easily checked by unscrewing the spark plugs and removing the distributor cover. The slider will point to either the 1st or 4th cylinder (you need to navigate by the cover on which the cylinder numbers are marked).
2. Remove the vacuum tube from the fitting, pull out the high-voltage wires from the distributor cover, unscrew the nut securing the distributor and remove it, having previously noted the position of the slider. During this operation, make sure that the gasket located between the ignition distributor and the cylinder block is not lost. By the way, it is also recommended to replace high-voltage wires with new ones when installing electronic ignition.
3. Take a new distributor, put a gasket on it and turn the shaft so that the slider is in the same position as on the old distributor. Install it onto the cylinder block and lightly tighten the fastening nut. Put on the cover, insert high voltage wires, connect them to the spark plugs. Connection diagram according to cylinder numbers - 1-3-4-2. Connect the vacuum tube.
4. Remove the old high voltage coil, install a new one in its place and connect the wires. By default, install parts purchased in one set. It comes with instructions and the wires are labeled. Otherwise, when dismantling, you should remember which of the wires was attached to the positive contact of the old coil.

1. Install the switch. VAZ models produced in recent years have a special place for it on the left side of the body (look as the car moves), next to the distributor. In older machines, you will have to carefully drill 2 holes and secure the switch with self-tapping screws. Connect the connector.
2. After installation, adjustment of the ignition timing is required. Ideally, this is done using a strobe light, but at first the adjustment can be done “by ear”. To do this, start the engine, let it run for half a minute, and then, by carefully rotating the distributor by the body in different directions at an angle of no more than 15°, achieve stable engine operation at idle. Tighten the distributor fastening nut.

After installing a new ignition on the VAZ 2106, it is necessary to clean the spark plugs and adjust the gap between the electrodes. The gap size can be in the range of 0.8-0.9 mm.

The condition for quick engine starting and uninterrupted operation is that the ignition is set correctly. Due to its incorrect installation, it can happen, and its result will be serious consequences and. Experienced drivers set the ignition by eye, others use a strobe light, and beginners usually turn to a car service center. However, if the result is good, the move itself does not matter.

How to set the ignition of a VAZ 2105 correctly

The first signs of problems with ignition on a VAZ 2105 are clear - these are, first of all, poor engine starting, high fuel consumption, loss of power, pops in the carburetor or muffler, as well as failures when changing speed, accelerating or starting off. In the worst case, detonation or complete failure to start the engine, both cold and hot, may occur.

As we have already found out, the ignition timing should be within 3-5 degrees on the compression stroke. It remains to figure out how to determine the compression stroke in the first or any other cylinder. Since the marks on the pulley and on the front crankshaft cover correspond to TDC (top dead center) in the first cylinder, we will not argue with him and will find out how to determine the compression stroke in the first cylinder.

Ignition installation marks

To do this, look at the photo above and see three marks on the cover opposite mark 4 on the crankshaft pulley. Mark 3, the largest, corresponds to top dead center in the first cylinder . Marks 1 and 2 correspond to ignition timing angles of 10 and 5 degrees , respectively. At the same time, remember that the crankshaft rotates clockwise. Consequently, we have already found TDC and the angle itself; all that remains is to position the piston in the first cylinder precisely on the compression stroke.

To do this, unscrew the spark plug from the first cylinder, and instead put a paper plug in the hole or simply cover it with your thumb. Using a 38mm socket or a special wrench for the crankshaft nut, we rotate it clockwise until the plug pops out or our finger is pushed out by air pressure. Ready. All that remains is to accurately align the marks on the pulley with mark 2 on the cover.

Checking the position of the slider under the distributor cover

Now open the distributor cover and check the position of the slider. It should be directed towards the contact connector on the distributor cover for the first cylinder. If this is not the case, rearrange the slider. After this, we set the exact ignition timing.

Using a 13mm wrench, unscrew the distributor mount and turn it a few degrees until the contacts in the contact group close. At this moment, a spark should jump on the first cylinder. To determine this moment more accurately, we connect the test lamp with a minus to ground, and a plus to the low-voltage terminal from the distributor. By rotating the distributor, we calculate the moment when the lamp lights up, naturally, with the ignition on. Close the distributor cover and start the engine.

If necessary, adjust the gap between the contacts with an adjusting screw and control it with a feeler gauge 0.35-0.45 mm

If we have a strobe light at hand, we don’t need to disassemble anything. To check the ignition timing on a VAZ 2105, it is enough to connect the strobe with one high-voltage wire to the terminal on the first cylinder from the distributor cover, and then connect the standard high-voltage wire to the tee of the device. We connect the low-voltage wire to the output from the distributor or to the coil, and the strobe power wires to the battery. Depending on the design of the strobe, the connection diagram to the battery may differ.

When and why do you need to adjust the ignition?

First, a little theory. If the working mixture in the cylinders burned instantly, then there would be no problems with advance in principle. Set it on fire at top dead center and everything is fine. But the mixture does not burn instantly: it takes milliseconds. In this case, the actual rotation speed of the crankshaft is, of course, not constant. Therefore, you cannot stupidly ignite the mixture at the same time under different engine operating modes: it will burn either too early or too late. The result will always be disappointing - the engine pulls poorly, overheats, runs unstably, detonates, etc.

In particular, if you start “sparking” too early ( large

), then the gas pressure will increase sharply until the piston reaches top dead center, preventing its movement.
Because of this, power will decrease and efficiency will deteriorate, it will lose throttle response and will twitch at low speeds. With late sparking ( low CV
), the mixture will burn for a long time with an expanding volume, and therefore the gas pressure will be significantly lower than the calculated one. Power and efficiency will decrease, and the engine will greatly decrease, since the mixture will burn out throughout the entire expansion stroke.

There is only one treatment method - ignite the working mixture according to the speed and load on the engine. In addition, adjustments to the SOP may be required when switching to. By the way, on very ancient cars (at the beginning of the last century), the ignition timing was regulated by the driver: a special handle was provided. But it soon disappeared, because the engine acquired a distributor with a centrifugal mechanism inside.

The centrifugal regulator usually contained a pair of weights balanced by springs. As the rotation speed increased, the weights diverged to the sides and rotated the support plate on which the breaker was located. The higher the rotation speed, the more the weights diverge and the higher the SOP becomes.

The further pursuit of efficiency added a vacuum colleague to the centrifugal regulator as assistants. The fact is that as the load increases, the filling of the cylinders with the combustible mixture also increases, since the driver puts more pressure on the accelerator. At the same time, the percentage of residual gases in the working mixture decreases, which helps to increase the combustion rate. Therefore, the SOP must be reduced.

On the contrary, when the load on the engine decreases, the filling of the cylinders decreases, the content of residual gases increases, and therefore the working mixture will burn more slowly. In this case, the OZ needs to be increased. This problem is solved by a vacuum regulator that monitors the vacuum in the engine intake pipe. The higher the load, the lower the vacuum, and vice versa. In most classic engines, centrifugal and vacuum regulators work together.

Let's consider setting the ignition timing (ignition timing) on ​​“classic” VAZ 2101, 2102, 2103, 2104, 2105, 2106, 2107, 2121 cars with a contact ignition system and their modifications.
The need to set the ignition timing may arise after removing and installing the ignition distributor (distributor), or when trying to more optimally configure engine operation. Incorrectly set ignition timing threatens to cause a number of problems in engine operation. Here are some of them: a drop in power and throttle response, increased fuel consumption, unstable idling, problems with starting the engine, shots and pops in the muffler, black smoke from the muffler, burning out valves, etc. Necessary tools
All work on setting the ignition timing on cars VAZ 2101-2107 can be carried out without the use of any special devices or devices. Using a strobe light or a warning lamp does not make much sense, since after setting the ignition timing, you will need to check its correctness on a moving car. The only tools you will need are:

— Open-end or socket wrench 13 mm.

— Open-end or special wrench 38 mm.

Preparatory work

— Put the car on the handbrake;

Setting the ignition timing on VAZ 2101-2107 cars

We set the ignition timing for 92nd gasoline.

1. Combine the mark on the crankshaft pulley and the mark on the front engine cover (the middle of the three available there).

To do this, use a special wrench (or a 38 mm open-end wrench) to slowly rotate the crankshaft by the ratchet until they coincide.

2. Install the distributor with latches parallel to the engine, the contact of the slider should look at the 4th cylinder (identify by the distributor cover).

The breaker contacts must be closed. Lightly press the distributor body with the holder.

3. Turn on the ignition and slowly turn the distributor housing until the breaker contacts open. A spark will jump between the contacts.

This will be the desired ignition timing. Use a 13 mm wrench to tighten the distributor holder nut.

Checking the correct ignition timing

When driving a car at a speed of 45-50 km/h in 4th gear on a flat road, sharply, for a short time, press the gas pedal. At the same time, listen to the engine. A short-term detonation - 1-3 seconds (knock of “fingers”) indicates the correct setting of the ignition timing, a long-term detonation - no detonation. It is necessary to adjust the advance angle by rotating the distributor (counterclockwise - we make the ignition earlier, clockwise - later). Then check again.

Notes and additions

— There are situations when, with a correctly set ignition timing (short detonation when driving), on VAZ 2101-2107 vehicles, engine idle leaves much to be desired. In these cases, many simply turn the distributor, setting the ignition a little earlier to stabilize the idle speed. It is advisable to eliminate this malfunction by adjusting the carburetor, and not by rotating the distributor, since the previously established correct ignition timing is lost.

Every owner of the legendary classic VAZ 2106 model knows well all the problems associated with the operation of this car, since in most cases he eliminates them on his own. Such problems also include malfunctions of the contact (cam) ignition system of the VAZ 2106. Constantly burning contacts required cleaning and adjustment; due to play in the bearing and distributor bushing, the engine operation resembled “shaking,” especially at idle. The electronic ignition system is designed to solve all these emerging problems.

How to set the ignition

Ignition timing directly affects the performance of the vehicle. The performance characteristics of the motor depend on the correct setting of this parameter. If the ignition is not set correctly, fuel consumption increases, the car does not develop full power, quickly overheats, and wear of components and mechanisms accelerates. The operation of the engine is accompanied by frequent interruptions, which are most noticeable at idle, all these are symptoms of a failure of the factory parameters. Below we will look at how to set the ignition of the VAZ-2105 (2106, 2109).

Required tools:

• key to "13";
• spark plug key;
• control (a voltmeter or a 12-volt light bulb can be used);

You can set the ignition on the first or fourth cylinder. On our website you can see a description of the ignition installation on the first cylinder.

1. Short mark with a leading angle of 10°.
2. Average - 5°.
3. Long - 0°.

The top dead center is indicated on the rim of the pulley; opposite TDC there is a special shoulder on the pulley.

Where to start setting the ignition

Before you begin directly setting up the ignition system, you need to check a number of components and mechanisms.

Spark plug . Make sure they are in good condition. If there is carbon deposits on their surface, remove it. Also, do not forget to adjust the spark plug gap.

Breaker contacts . Check the contacts; if they show signs of metal burnout or corrosion, replace them. It is not recommended to repair these segments; they do not cost much money and new ones will last much longer.

Capacitor . To check, you must use a special charge-discharge tester. The most optimal would be a pointer device; it will allow you to determine as accurately as possible the strength of the current flow, which should pass smoothly and slowly.

Ignition coil . Test the contacts with a tester, but first thoroughly clean the coil, distributor cap and distributor from dirt. If the lid has carbon deposits, it must be replaced with a new analogue.

Carburetor . Test the carburetor; if it is not in working order or minor malfunctions were discovered during the diagnostic process, it is recommended to repair it before proceeding with the ignition adjustment.

Ignition installation steps

To understand how to set the ignition of the VAZ-2109, (2105, 2106), just read the instructions described below. The design of these models is almost identical. To implement this task, it is necessary to study the design features of the system. The adjustment is carried out in three stages:

1. First you need to unscrew the spark plug above the first cylinder. The empty connector must be closed with a plug or finger; in the process, start turning the crankshaft with a wrench until you find the compression stroke. 2. The ignition crankshaft pulley has a special line, which should be located at the same level as the mark located on the front cover. 3. The distributor should be installed in such a position that the slider is placed parallel to the cover to which the high-voltage cable connector is connected.

Step-by-step instructions for performing repair work

You can set the ignition on the VAZ 2106 engine to 4 or 1 cylinder. The operating algorithm is slightly different depending on the cylinder with which the work is being done. Also in this article we will tell you how to set the electronic ignition on a VAZ 2106. First of all, you need to determine which marks will set the ignition. The ignition is set according to the marks on the timing belt. The long mark corresponds to zero ignition, the middle mark corresponds to five degrees of the angle, the short mark corresponds to ten degrees of the advance angle.

You can also find a top dead center mark on the pulley rim, and there is also a small bump on the pulley located opposite the top dead center mark. It is according to these marks that you should set the contactless ignition on the VAZ 2106. You need to unscrew the spark plug from the 1st cylinder with a spark plug wrench, close the spark plug hole that appears with a plug or your finger.

Using a special key, you need to turn the crankshaft before the compression stroke begins. This compression stroke begins as soon as the piston begins to move upward. Compression can be determined by the pressure in the spark plug hole. You need to turn the crankshaft until the mark on the cover located on the timing belt matches. If you use low-octane fuel, then you need to align the mark on the crankshaft pulley with the long mark, which equals zero advance angle. If you fill the engine with 92 gasoline, then you need to combine the mark with medium risk.

Next, unfasten the latches and remove the distributor cover.

After turning the crankshaft, the rotor will be in a position where the rotor contact in the distributor is directed towards the first cylinder. Having aligned the marks, you should draw a line from the distributor that passes through the cover latches and is directed parallel to the engine axis. If such an imaginary line does not intersect the cover latches, it is imperative to make the appropriate adjustment: Unscrew the nut that secures the distributor, and then pull the distributor up. When rotating the rotor axis, it should be aligned parallel to the engine axis.

We install the distributor in place, fix it with the fastening nut, but do not fully tighten it.

Next you will need a test lamp or voltmeter. This device must be connected at one end to the output of the ignition coil, while the second wire from the lamp is connected to ground or to the carburetor.

Turn on the ignition and smoothly turn the distributor. It is necessary to turn until the control lamp goes out. If the lamp does not initially light, then no adjustment is required. After this, we begin to turn the distributor counterclockwise. As soon as the warning light comes on, secure the distributor by tightening the nut. Turn on the ignition and install the distributor in place.

Checking the correctness of the work done is not difficult. We accelerate the car to a speed of 40 kilometers and sharply press the gas in fourth gear. If such manipulations cause detonation that does not go away when the car accelerates, early ignition is set. The absence of detonation indicates late ignition. When the ignition is set to early, the distributor should be turned approximately one notch. If the ignition is set to late, then on the contrary, it is turned counterclockwise by one division.

Setting the ignition timing

Let's look in detail at how to set the ignition of a VAZ 2106 (2105, 2109) and what is needed for this. First you should prepare the following tools: a 13mm wrench, a voltmeter or a light bulb for control. The gas distributor cap has three special marks. They are used to adjust the ignition timing. The labels correspond to the following values:

short position for an angle of 10 degrees;

middle position—5;

long label - 0.

Typically, the pulley rim also has a TDC mark. Opposite it, a tide is placed on the hub. The ignition timing value is adjusted only for cylinders 1 and 4. Sequence of stages:

Remove the spark plug from cylinder 1 and plug the hole with a finger or plug. Using a wrench, turn the crankshaft until pressure builds up in cylinder 1 to push out the plug. Then continue turning the crankshaft until one of the marks aligns with the mark on the timing cover.

If the car is operated on 92 (95) grade gasoline, align the mark with the middle mark; if you use fuel with an octane rating of less than 92, place the mark opposite the long strip. Disconnect the distributor. After performing the above operations, the distributor rotor should be in a position in which the outer contact is directed towards the 1st cylinder.

By aligning the marks, you should get an imaginary line running parallel to the motor axis. If you cannot achieve this result, you must proceed with the following operations. First, unscrew the distributor fastening nut using the appropriate wrench, lift the distributor to the top and turn the mechanism to the desired position by turning the rotor axis. Place the part in place, fix it, but do not fully tighten the fastening segments. Next, we will look at the immediate steps of how to set the ignition.

Prepare a test light (voltmeter). Connect one wire to the output of the coil, to which the low-voltage cable of the distributor should be connected. And connect the other wire to body ground.

Turn on the ignition. At this moment the warning lamp should light up. Next you need to make it go out. If the lamp does not light, skip the next step.

Turn the distributor clockwise until the lamp stops burning (no voltage).

Slowly turn the distributor counterclockwise until the control lamp lights up (voltage appears). After this, fix the location of the part and tighten the fastening segments.

Turn on the ignition and place the distributor cap in its original place.

Recommendations for displaying the VAZ 2106 ignition at home

1. first cylinder, cover the spark plug hole with your finger or rubber plug.

How to set the ignition of a VAZ 2106 on your own

1. Using a special wrench, turn the crankshaft until compression occurs in the 1st cylinder (the piston rises up). The plug will fly out or you will feel pressure on your finger.
2. Turn until the mark on the pulley coincides with the mark on the timing cover. When using “92” or “95” grade of gasoline, you need to align the mark with the middle arrow, if the grade is lower, then with the long one (corresponding to zero advance angle).
3. Unfasten the latches and remove the cover from the ignition distributor.
4. After the crankshaft has been turned, the distributor rotor should be in a position in which its outer contact is directed towards cylinder 1 on the distributor cap.

1. After aligning the marks, it is worth considering the distributor. Try drawing an imaginary line through the latches on the cover, parallel to the axis of the motor. If this does not work, you need to do the following:
2. Turn the distributor up and unscrew the nut securing the distributor. While rotating the rotor axis, align it parallel to the engine axis.
3. Install the distributor, tighten the nut, but do not tighten it completely.
4. Upon completion of all these procedures, you can begin the process of adjusting the ignition.
5. Connect the “control”: attach one end to ground, install the other at the output of the ignition coil with the low-voltage distributor wire.
6. Turn on the ignition. Turn the distributor clockwise until the indicator light goes out. If the light does not light up initially, there is no need to turn the distributor.
7. Rotate the distributor from right to left, fix the location of the distributor and tighten the fastening nut while the warning lamp lights up.
8. Turn off the ignition and replace the distributor cap.

You can check whether the ignition is set correctly as follows:

1. Start the engine and start driving.
2. Accelerate the car to 45 kilometers per hour, engage 4th gear, and sharply press the gas pedal.
3. After a few seconds, detonation will appear (ringing of fingers, popping noises). It will disappear when the car accelerates further.
4. The conclusion that ignition is “early”
   can be made if detonation does not disappear when the car accelerates, and that
   “later”
   can be drawn if detonation does not occur. In the first case, turn from left to right by 0.5-1 divisions, in the second - from right to left by the same number of divisions. As soon as you manage to adjust the ignition, use paint to mark the position of the middle mark on the distributor body.

If all actions are performed correctly, you can consider that you were able to set the ignition of the VAZ 2106

Below is a video that shows the above process in detail.

A properly functioning ignition system is the key to reliable engine operation and easy starting. In addition, fuel consumption and dynamic characteristics also depend on the timing of ignition. Incorrect timing can cause engine detonation, which can lead to very disastrous consequences. Let's see how to install ignitions on a VAZ-2106, and also talk about electronic ignition and installing an ignition switch on this model from AvtoVAZ.
