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.

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.

Verifying that the settings are correct

After we have dealt with the question of how to install the ignition on a VAZ 2109, we will consider the process of checking whether the adjustment work has been carried out correctly.

So, if configured correctly:

during the process of rapid acceleration of the power plant (when the car is warm), there is no violation of the stability of its operation;
When the car is moving at a speed of about 50 km/h in fourth speed and during sharp acceleration, there should be a short detonation of the engine. If there is no detonation, ignition is later; if it is present, but does not go through, it is earlier. We make the adjustment by turning the distributor in one direction or another.

Remember that it is often impossible to achieve stable operation of the power unit due to improper operation of the fuel system or even due to low quality gasoline. In this kind of situation, the best way out of it would be to set the carburetor to the most optimal operating mode and then adjust the ignition timing.

Very often, these ignition system malfunctions are caused by a trivial reason - an incorrectly set ignition.

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.

Basic technical concepts

The ignition system is a variety of interconnected instruments and devices that guarantee the appearance of an electrical discharge, which in turn ignites the mixture of fuel and air in the internal combustion engine system. This system plays a huge role in the vehicle’s technical equipment and electrical equipment.

We are not interested in the entire ignition system, but only in the moment the spark appears, which determines the correct operation of the entire system. This moment is called the ignition moment, because. determines the time for ignition of the working mixture in compressed form. Incorrectly set ignition timing entails many problems in the operation of the car. With the help of this article you will learn how to identify the problem, what it means and how to fix it.

VAZ-21099: under the hood

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.

Adjusting the ignition by light bulb

If the strobe light does not turn on or you simply do not have one, then a malfunction of the switch or other element that led to the need for adjustment can be solved using a light bulb. By the way, switch malfunction is a problem for many. So, to set the spark moment on the module you will need a regular 12 volt lamp. The procedure itself consists of setting the module torque by loosening the spark regulator lock.

The procedure is carried out as follows:

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.

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.

It is convenient and quick to work with invoices, acts and invoices in the My Business service, you can fill out invoices, acts and invoices online.

The main purpose of the account is to speed up settlements between counterparties of cooperation. An invoice can be thought of as a documented preliminary agreement in which the seller sets a price for his product or service, after which the buyer makes payment. As a rule, in such cases the invoice is issued in a single copy.

In the financial sector, an invoice belongs to the category of business documents that are used by legal entities and individual entrepreneurs who are VAT payers. As a rule, the invoice is issued by the seller (performer) after the sale of goods or services. In addition, this document can be used to confirm payment of VAT and excise duty. Sometimes an invoice is used to inform the buyer about the country of origin of the goods, transmit information about the customs declaration number, etc. In order for a document to be considered a basis for deducting VAT from the buyer, it must be written out in a strictly established form and executed in two copies.

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.

Invoice for payment from an individual entrepreneur or LLC

Since the account is not an accounting document, today there is no strict form approving its type. The invoice can be issued in paper or electronic form, but it must include the following information:

details of a legal entity or individual entrepreneur (name of organization, identification code, legal address, legal form);
bank details (name, address, correspondent and current account, BIC);
codes (OKPO, OKONH).

Having indicated all the necessary details, the document preparer must write down the invoice number, date it and indicate the presence or absence of VAT. At the end of the invoice, the individual entrepreneur or legal entity indicates his last name, initials and personal signature. According to the rules, there is no need to put a stamp.

Most often, an invoice is drawn up in standard office programs - Word or Excel, in which you can create a template to enter the necessary data into it. There are also special programs for generating invoices, which provide a number of additional functions: automatic recording of completed transactions, tracking payments, eliminating possible errors, etc.

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.

When to issue an invoice

Our legislation does not prohibit making transactions without an account. Therefore, if the terms of the cooperation agreement between the counterparties do not oblige the seller to issue an invoice for payment, this document need not be drawn up. In this case, the buyer will pay for the product or service based on the agreement. But there are situations when you can’t do without an account. Most often, the need for this document arises when the buyer must transfer to the seller an amount that was not initially determined. For example, an invoice is usually issued when paying for communication services, because In contracts of this category, the exact amount of payment is not specified in advance.

In addition, an invoice must be issued in cases where an organization carries out transactions that are subject to VAT, as well as in a number of other situations prescribed by law.

This invoice is issued to the buyer (customer):

an organization that is exempt from VAT (Article No. 145 of the Tax Code of the Russian Federation);
an organization that sells goods (services) under an agency agreement on its own behalf, if the general taxation system is used (clause 1 of Article 169 of the Tax Code of the Russian Federation);
an organization that has received partial payment (advance payment) from the customer for the sale of goods (services) (Article 168 of the Tax Code of the Russian Federation).
