Setting the ignition timing (ignition timing) on VAZ-2108, 2109, 21099 cars

Note! Before starting work, we advise you to stock up on a strobe light, because without it, checking the ignition timing will not be very convenient! (What is a car strobe light?)

When should ignition timing be set? Due to incorrectly set ignition timing, the following changes will occur in the car engine:

Firstly, the car will lose its speed qualities, that is, it will drive worse.
The car will also respond worse to the gas pedal, and small dips will appear when you press it.
To all this can be added unstable engine operation at idle.
It may also be difficult to start the engine.
Also, the car’s engine may overheat more often.
And in conclusion, I would like to note that the engine’s fuel consumption may also increase.

How to set the ignition timing on a VAZ 2108-VAZ 21099?

Setting the ignition timing and checking it:

Note! Before you start, be sure to keep one fact in mind. The ignition is installed strictly at idle speed, while the crankshaft rotation should be in the region of “820-900” rpm!

1) First, disconnect the thin hose from the vacuum regulator fitting.

2) Next, in order to check the ignition timing, perform the following operations:

• Connect the “positive” clamp that comes from the strobe light to the “plus” terminal located on the battery.

• Then connect everything to the same battery, but only this time to the “minus” terminal, the “ground” clamp that comes from the strobe light.

• Next, disconnect the tip of the high-voltage wire from the terminal of the “first cylinder” distributor cover.

Note! You can see where the “first cylinder” output is located on the distributor cap by the markings on the cap itself, see the photo for more details:

• Now connect the sensor that comes from the strobe light to the terminal of the “first cylinder”, and after the sensor is connected, install a high-voltage wire on this sensor.

• Then remove the rubber plug that covers the hole in the clutch housing to prevent dirt from getting into it.

• Then insert a screwdriver into the hole in the clutch housing, and then rotate the flywheel until the mark on the flywheel is between the cutout and the division. (Where the mark is located, as well as the cutout and division, look at the photo just below, which is located above the “Note!” section)

• Next, start the car’s engine, and then point the flashing strobe light at the hole in the clutch boat.

• While the strobe light is flashing, the mark that is stamped on the flywheel should visually appear motionless at this time.

Note! If the ignition on your car is installed correctly, then in this case the mark indicated by the number “1” must necessarily be located between the cutout “2” and the division “3”. If your “1” mark is placed outside the cutout and division, then adjust the ignition timing!

3) After all operations, if your ignition timing is not correct, then first loosen the three nuts that secure the distributor.

4) And then turn the distributor itself until the marks align as desired.

Ignition timing: features, rules and recommendations

Note! If you need to increase the ignition timing, then gradually turn the distributor slightly towards o. And if, on the contrary, you need to reduce the ignition timing, then in this case turn the distributor closer to o. In these “plus” and “minus” intervals, set the ignition angle that will correspond to your car!

5) When the ignition timing is set, install all previously parts in their place.

Additional information: To make it clearer for you, watch the video in which “Nail” describes everything in detail:

Probably every motorist who owns a car of the VAZ 2108-09 family has encountered problems with the ignition system. Very often, these malfunctions are caused by a trivial reason - an incorrectly set ignition. It is the question of how to set the ignition on a VAZ 2109 carburetor and injector that we will talk about below.

Checking the advance angle setting

To check how correctly we have set the ignition timing and how well the brand of gasoline corresponds to the inscription on the gas station, we drive out onto a flat section of the road, accelerate to 40 km/h in fourth gear and sharply press the gas pedal. In this case, a short-term (3-4 seconds) detonation should occur in the engine. That is, a knocking, ringing, clattering sound of the piston pins should be heard. If the ringing does not stop after 4 seconds, the ignition is too early. If the knock does not appear at all, then the ignition is late. If necessary, we adjust the ignition angle by eye.

This way you can quickly and easily set the ignition timing on your VAZ 21099, and at the same time check the quality of the fuel. Don't tap your fingers in vain, and have a good trip!

System design

Before we begin to consider the adjustment process, we consider it necessary to understand the diagram and principle of operation of the system. Vehicles of the VAZ 2109 model range are equipped with a non-contact ignition system. The connection diagram of all elements is as follows:

The operating principle of the system is not complicated. In order for a spark to begin to be produced, the motor shaft must turn. Simultaneously with its rotation, the camshaft will also turn. As a result of this, the sensor generates a signal that will be sent to the switch. The “K” terminal of the coil will connect to the common wire (to “ground”), as a result of which a spark will occur on the main wire. At the moment when the working distributor slider connects the main wire with one or another high-voltage wire on the corresponding spark plug, a spark will appear and the car engine will start.

If the setting is made incorrectly, the candles work in the wrong time modes. Consequently, such a violation becomes the cause of unstable operation of the entire power unit.

Checking the ignition

To check the functionality of the ignition in a car with an eight-valve injection engine, you will need:

a computer with a pre-installed diagnostic program;
device for conducting tests;
wrench with screwdriver.

So, if you decide to check the entire system, you should not rush and test the ignition module before a comprehensive check. The point is that the system must function properly with all connected devices. Turn the key in the ignition and connect to ground. After turning on the ignition, fuel should begin to flow into the system. At this moment, carefully monitor the indicators: if the red signal lights up, determine the nature of the problem using a special program.

When everything is ready, you can check the operation of the throttle valve. To do this, you need to turn on the ignition again, take a tester and use it to find out what voltage is coming to the on-board computer sensor. Everything is normal if, according to the readings, you get the following values: on-board system voltage is greater than or equal to 12 V, sensor - 0.5 V, damper opening degree - up to 1%.

Next, press the accelerator. At this point, the readings should change between 4.5 V and 90%. If you want to achieve the best result, increase the throttle reading to 100%. Finally, stop supplying additional air and open the system to 50%. The final step in adjusting the throttle valve is to close it completely.

Preparatory activities and necessary tools

Installing the ignition of a VAZ 2109 carburetor begins with preparatory activities. In particular, you need:

Warm up the car engine;
Set the parking brake and install wheel chocks under the rear wheels.

Remember that you cannot ignore safety rules, because a car is a highly dangerous vehicle, and failure to comply with safety rules when driving, servicing and repairing it can cost you dearly.

An important point: before you start work, you should make sure that the carburetor is correctly configured on the car. It would not be superfluous to carry out a visual inspection of all elements of the system. If we are talking about a carburetor car, special attention should be paid to inspecting the condition of the distributor.

If you have a car with an injection engine, it is worth checking the ignition module for serviceability. The thing is that, as practice shows, it is this module that fails most often and is the reason for the inoperability of the entire system.

To complete the work we need:

strobe;
a set of keys.

Ignition control control

In order to ensure that the settings are correct, it is necessary to perform some control measures. Let's look at the list of these events:

We warm up the power unit to “operating” temperature and smoothly press the accelerator pedal, bringing the speed to maximum. There should be no “failures” in the operation of the power plant.
We drive out onto a flat section of the roadway and accelerate the car to a speed of 40-50 kilometers per hour.
Press the accelerator pedal sharply. The occurrence of short-term detonation indicates that the VAZ 2109 ignition adjustment was performed correctly.

In conclusion of our article, a few words about injection “nines”. The ignition module installed on the VAZ 2109 injector is adjusted through programming of the ECU (electronic control unit). Performing such a procedure independently is possible (theoretically), but requires special software created for a specific type of controller and certain, fairly specific knowledge.

How to correctly set the ignition on a VAZ 2109 carburetor - detailed instructions

The setup process is as follows:

1. Start the car engine and ensure that the engine speed is approximately 800 rpm. To set the idle speed within such limits, it is enough to use a slotted screwdriver to adjust the screw responsible for the amount of fuel mixture in the carburetor.

2. After setting the idle speed to the above value, turn off the car engine.

3. Disconnect the rubber hose from the vacuum corrector. Carefully bend the hose approximately in the middle or plug it with a screw of a suitable diameter.

4. Connect the positive terminal of the strobe to the “+” terminal of the battery;

5. Connect the negative wire of the strobe to the “-” terminal of the battery;

6. Disconnect the spark plug wire from the socket of the first cylinder as shown in the image:

Disconnect the spark plug wire

7. Install the strobe sensor into the socket and connect the high-voltage wire to it;

8. Remove the plug from the clutch housing hatch:

Removing the stub

9. Turn on the ignition and start the engine. We direct the actively changing luminous flux generated by the strobe into the clutch housing hatch:

We direct the strobe into the clutch housing hatch

10. When the light is flashing, it seems that the mark located on the flywheel is stationary. If the ignition is installed correctly, the first mark should be between the technological notch and the previous mark on the scale.

Do-it-yourself ignition system repair

So, if problems with the engine indicate problems with the ignition system, you should proceed with immediate repairs. The essence of the work being carried out comes down to installing or setting the correct ignition timing. The engine will only run stably when you adjust the ignition system. To begin repairing this mechanism, you need to stock up on some tools:

strobe;
tachometer;
flat screwdriver;
key to 10.

Having a strobe light on hand will greatly facilitate the process of setting up the ignition, so we recommend purchasing one for personal use.

Before you start setting the ignition timing and angle, do some preparatory work. The first thing you need to do is start the engine. Then either wait or rev the engine until the engine temperature is 90 degrees Celsius and the idle speed should be around 800 rpm (use a tachometer to determine this parameter). To obtain the required values, use the fuel regulator located on the carburetor body.

As the engine operating temperature reaches 90 degrees, remove the silicone tube through which the discharge occurs from the fitting. The lever for adjusting the fuel supply is located on the ignition timing distributor panel or distributor. The distributor is attached to the carburetor itself. Place your finger on the other edge of the tube and check if there is a vacuum effect. It can be checked very simply: if your finger is stuck to the tube, it is there; if not, then there is no effect either. Now you need to reduce the number of revolutions until the vacuum completely disappears.

Then turn off the engine. Bend the silicone tube so that there is no gap. Take a 10mm wrench and unscrew the distributor nuts. The photo above clearly shows the flywheel and crankcase hatch. The gearbox housing contains a hatch with a flywheel scale. Remove the plug and, if there is dirt, wipe it off the inspection hatch. On the scale you will see stripes responsible for correct ignition setting. Next we focus on them.

Using a flathead screwdriver, rotate the flywheel to the long line on the scale. Before setting the ignition, you need to align the long strip exactly opposite the triangular cutout on the scale. The fact is that this position means a zero ignition angle. At the moment when the long strip is in this position, the first and fourth cylinders remain in a fixed position.

If, due to poor visibility, you doubt that the selected strip is the longest, it is worth re-evaluating its location relative to the camshaft. To do this, you need to remove the timing belt cover and see if the mark you are interested in matches the mark on the rear cover.

Next you need to use a strobe light. To connect it, you need to perform several simple manipulations:

first connect the red wire to the positive on the coil;
then place the dark wire anywhere on the body;
and secure the mount to the fourth cylinder along with the wires.

Before connecting the device, it is better to read the instructions for use.

Incandescent lamp instead of strobe light

Many car owners will ask a completely fair question: how to adjust the ignition of a VAZ 2109 in the absence of a strobe light. Of course, it is more correct to work with a strobe, especially since in this case it is possible to carry out adjustment and adjustment work as accurately as possible. However, there is another method that is useful for those who, for one reason or another, do not want to purchase a strobe.

To work, we need an ordinary incandescent lamp designed for an operating voltage of 12V. The entire algorithm of actions is as follows:

Disconnect the wire from the distributor that goes to the ignition coil
We connect one terminal of an incandescent light bulb to the wire. We connect the second wire from the lamp to ground.
As in the case when setting the ignition of a VAZ 2109 using a strobe light, use a spanner to loosen the distributor fastening nuts.
Turn on the ignition. The incandescent lamp should light up.
Gradually turn the distributor until the lamp stops glowing. After this, turn the distributor slightly in the other direction. As soon as the lamp starts to glow again, you can tighten the fastening nuts.

Of course, the method described above cannot provide the highest possible adjustment accuracy. However, with its help it is quite possible to achieve more or less correct and stable operation of the power unit.

Setting with a light bulb

If you do not have a strobe, then the torque can be adjusted using a conventional control lamp; in particular, you will need a 12-volt lighting source.

How to set the SOP torque using a control light:

To correctly adjust the torque of the RCD in the Nine with a carburetor engine, you will need to crank the crankshaft until the marks coincide. To turn the crankshaft you will need a special wrench. If the key is missing, you can set the lever on the gearbox to fourth speed, and then manually turn the shaft until the marks match.
To make the adjustment, you will need to connect the test light to the wire and switchgear with the coil. The second contact from the light source is connected to ground, that is, the vehicle body.
Next, on the switchgear housing you will need to slightly loosen the bolts that secure it. Then you will need to turn the key in the ignition. If everything is working correctly, the light should light up.
After completing these steps, you will need to turn the housing of the distribution mechanism; it turns until the light stops burning. After this happens, the distributor housing will need to be turned in the opposite direction. The adjustment procedure stops the moment the lamp starts to light again. When this happens, the distributor no longer needs to be touched; it will be necessary to tighten the bolts that secure it (the author of the video about the implementation of this method is Nail Poroshin).

How to adjust the ignition on a VAZ 2109 - an alternative method

In addition to the adjustment methods described above using a strobe and a light bulb, you should remember one more method - adjustment using a standard tachometer. We emphasize that this method, like the method using a light bulb, cannot provide high accuracy of adjustment. Moreover, it is characterized by one significant drawback - it is impossible to carry out the adjustment yourself; you will need to hire an assistant. So:

Your assistant is located behind the wheel of the car. He turns on the ignition and monitors the readings of the standard tachometer on the instrument panel.
You loosen the nuts securing the distributor and turn it a little.
Your assistant turns the ignition key. The tachometer needle should quickly deflect and return to zero.
You need to ensure that the distributor remains in a position in which the tachometer needle deflects.

You may notice that this method requires patience and quite a lot of time. As practice shows, it is not possible to adjust the ignition quickly and the first time using this method . Therefore, we recommend using it only in extreme cases.

Testing the configured ignition

The functionality of the system in question is checked in the following way:

the power plant is warmed up to operating condition;
slowly press the accelerator, increasing the speed to maximum.

After this, the car is taken out onto the track and accelerated to 50 kilometers. Then they quickly press the accelerator pedal again. Ideally, a short detonation should occur. If it lasts for a long time, this indicates that the ignition is triggered too quickly. At the same time, slowness is indicated by the absence of the characteristic sound of knocking “fingers.”

All of the methods described above are suitable for carburetor models. In injection cars, the ignition is controlled via the on-board computer. In theory, it is possible to carry out the entire process at home, but this will require a PC and specialized software, as well as a number of very specific knowledge. For this reason, it is better to contact a car service for setup. Inept actions often lead to breakdowns, which have to be fixed at a much higher cost.

How to set the ignition on a VAZ 2109 injector

Above we described the process of adjusting carburetor engines. However, there are VAZ modifications equipped with injection power units. How to set the ignition on a VAZ 2109 with such an engine?

First of all, you should pay attention that in the case of injection engines, they do not have a distributor and a Hall sensor. At the same time, the system provides two ignition coils at once, and, accordingly, two switches. The main difference between the injection system and the classic one is that the control signals are generated by a special electronic unit. The operating principle is as follows:

Operating principle of the injection system

Thus, there is simply no need for a distributor, because it is the electronic control unit that determines in which cylinder and at what point in time there should be a spark. Signals from the control unit are supplied to the inputs of the switches, and from them to the ignition coils. One switch is responsible for sparking in the first and third cylinders, and the second - in the second and fourth.

As in the case of engines with a carburetor fuel system, adjustment is carried out according to special technological risks. The ignition marks of the VAZ 2109 injector are shown in the photo below:

Ignition marks VAZ 2109 injector

Please note that it is not possible to configure the injection engine system yourself. The thing is that this operation involves making changes to the software of the microcontroller of the electronic control unit. Of course, each specific microcontroller has its own specific firmware. Moreover, there are also non-standard firmwares, for example, with settings for a sporty driving style.

Only an experienced specialist with certain knowledge can flash an electronic control unit. Therefore, if malfunctions occur in the ignition system of an injection engine, you should seek help from a trusted car service center.

Dual-circuit (sliderless) ignition

Of course, I needed to buy several devices from my beloved TAZ donors: Ignition coil. seems to be from Kalina. It consists of two double-spark coils in one housing, which is ideal for a four-pot motor.

Switches for TAZ-2108, two pieces.

The distributor was converted to a Hall sensor, while I was waiting for the curtain blanks from the turner, I made a straight curtain with a file and deployed the sensor in order to somehow start the system.

To tie it all together, I wove a braid of wires. The small black box in the center of the frame contains just the signal inverter circuit for the second switch.

I assembled everything on the table, checked how it worked: Well, on the car. It’s gotten a little better at the low end, and it doesn’t adjust so fiercely anymore. Tags: Volga
