VAZ 2107: ignition installation (manual and diagram). How to set the ignition on VAZ 2107

In this article will be told about how the VAZ 2107 is installed ignition. This car can be installed as a contactless, as well as a contact ignition system. Regardless of which system design is installed in the car, all work is almost identical. The appearance and drive of the BSZ rammer and the contact is the same, the only difference is that in the first case a Hall sensor is used instead of a mechanical interrupter. There is also a difference in the power wire that is connected to the trambler.

Replacement of the tumbler

To make a complete replacement of the trambler on the car VAZ 2107, you need to use only one tool - the key to "13". First, unplug all the wires from the cover that go to the spark plugs. Between the carburettor and the trambler, a hose is laid for the normal functioning of the ignition timing advancer. To the ignition distributor goes a small wiring harness. He connects to it with a pad. After that, unscrew the nut that secures the body of the springboard to the internal combustion engine block.

Do this with a key on "13". Remove the washer and plate. Slightly pulling up, you can remove the body of the toggle switch from its place. The cost of the new valve for the car VAZ 2107, as well as for the entire classic series, about 800 rubles. In the event that it is planned to install a non-contact ignition VAZ 2107 instead of the classic one, you will have to spend about two thousand rubles. This is the average cost of a set of stores.

What is the adjustment for?

Everyone knows what the ignition timing is. This parameter of the system must be adjusted from time to time on any car equipped with a classic ignition system. This is done to reduce the consumption of gasoline, increase the resource of the internal combustion engine, and also to achieve the best characteristics of the dynamics and acceleration of the car.

You can divide all the procedures into several stages. First, the angle of the contact group in the "closed" position is corrected. Secondly, after this, only you can start to work with the lead ahead of the ignition. The fixation is in the most acceptable position. At the VAZ 2107 ignition installation is not over yet, it is necessary to adjust the adjustments.

Adjust settings

Having done all these actions, it is necessary to make a test run in order to carry out more precise control and make an adjustment. In the event that suddenly there were any irregularities when the engine is running. The value of the angle of the contact group in the "closed" position can be determined from the size of the gap of the group. This is extremely necessary to do in the tumblers, which are used in the contact and transistor ignition systems. But the non-contact ignition VAZ 2107 does not need adjustments of such.

Adjustment of the contact group

So, now in more detail on how to properly configure the ignition system on the six. First remove the cover from the distributor. Using the ratchet wrench, you must crank the crankshaft until you notice that the distance between the breaker contacts is at the maximum value. The fixing of the contact group is made with the help of two small bolts, for adjustment they need to be slightly weakened. If there is a non-contact ignition VAZ 2107, then you only need to set the advance angle.

It is best to do this with a key, not a screwdriver. As a rule, the tightening of these bolts is very strong, so you will rather damage their heads. For proper setup, you will need a probe with a thickness of 0.44 mm. Install it between the contacts and fix the position of the breaker. To do this, tighten both bolts. With this procedure, you can achieve the desired angle at which the contact group is closed.

Closed-loop angle

For the VAZ 2107 and similar models, the most suitable angle is 55 degrees. The error should not be more than three degrees. After the angle of the closed state has been adjusted, it is necessary to proceed to the next step. You should install the distributor in such a way that the ignition timing is ideal. Note that it is best to set the advance angle on engines that have significant wear, on the fourth cylinder. Adjustment to the first cylinder is possible only on new engines or after major repairs.

Ignition advance

Of course, you can make adjustments and by ear, but this is not very correct. It is necessary to correctly set the VAZ 2107 ignition timing in order to reduce fuel consumption and increase engine life. Before making adjustments, it is necessary to remove the hose from the vacuum corrector. A hole in the corrector is muffled. Warm up the engine to operating temperature, so that idle speed is kept at a normal level. Stop the engine and unscrew the nut that secures the distributor housing.

Stroboscope setting

The strobe must be connected to the negative and positive of the battery. Capacitive sensor is mounted on the armored pipe of the cylinder, on which the adjustment is carried out. Now about how on the VAZ 2107 the ignition is installed. From the strobe comes the emission of light. Beam it must be sent to the pulley crankshaft. To properly configure the ignition, you need to install the body of the trambler in such a position that the strobe, whose beam is parallel to the mark on the cover of the gas distribution mechanism, will slip when the mark on the pulley of the crankshaft is opposite it.

Please note that once the setup is completed, you still need to check the correctness on the track. To achieve the required ignition timing, you will need to rotate the entire distributor housing in the desired direction. After finding the desired position, fix it with a nut. Similarly, the VAZ 2107 non-contact ignition is installed, the timing of the advance is regulated in the same way.

How to check the correct settings on the go

To make sure that all the work is done correctly, you need to go to the track. Warm up the car and accelerate it on a flat road up to 50 km / h. Thus it is necessary to include the fourth speed and to move evenly. Press the accelerator pedal sharply. There should be short (about two seconds, no more) knocking, which gives out in detonation. At the same time, the car should gradually increase its speed. At VAZ 2107, the ignition can be considered complete if all conditions have been met.

In the event that you do not hear detonation knocking, you need to turn the body of the switch counterclockwise (a maximum of one division). Conversely, if the knocks last longer than 2 seconds, rotate the casing clockwise for a maximum of one division. If, on the road tests, you have made sure that the position of the distributor body has changed much more than it was set during tuning with the stroboscope, then only the presence of a breakdown in the internal combustion engine can be judged.

What do you need to consider?

Of course, such symptoms can be provoked by the wrong mixture in the carburetor. Before installing the ignition on the VAZ 2107, you need to make sure that all systems work stably. It is also possible that the vacuum regulator in the switch works incorrectly. It is possible that the bearings and bushings of the ignition distributor have a very large wear.

If the adjustment is correct, no malfunctions are detected, then you ensure yourself that the start of the motor and its operation will be as stable as possible. The dynamics of the car significantly improves, the consumption becomes lower, the resource of the engine increases several times. Consequently, the correct adjustment of the ignition timing will allow you to repair the engine and its systems as less as possible. And the ignition circuit of the VAZ 2107 is simple, identical to the one used on all classic models.
