One of the most common ways of setting the ignition is by adjusting with a 12V bulb. Suitable for all cars with a contact ignition system. On cars and transistor or thyristor systems, the voltage at the ends of the distributor is not enough to ignite the light bulb.
It is necessary
- - 12 V light bulb with soldered wires;
- - a set of probes;
- - special key for crankshaft rotation;
Instructions
Step 1
Adjust the angle of the closed state of the distributor contacts (UZSK). To do this, remove the cover of the breaker-distributor and clean the contacts with a file with a file, removing all the formed oxide bumps. After cleaning, make sure that the contacts are flat against each other. Correct if necessary by slightly bending the stationary contact.
Step 2
Turn the crankshaft until the distance between the distributor contacts is greatest. Unscrew the screw securing the contact group to the bearing plate and insert a 0.4 mm feeler gauge between the contacts. Select the position of the contact group, in which the stylus moves with force, and fix it by tightening the screw. Check the clearance with the 0, 35 and 0, 45 mm feeler gauges.
Step 3
Use the special key to rotate the crankshaft. If it is absent, rotate it slowly, gently pushing the car in fourth or fifth gear. Do not use a starter for this purpose. Having established the required clearance, the required value of the UZSK is automatically set, but only in new distributors assembled without violating the technology and dimensions. Therefore, make additional adjustments.
Step 4
Remove the central high-voltage wire from the breaker cover and place it against the ground. Connect a light bulb to the wire from the distributor to the ignition coil. Turn on the ignition: the light will be on when the breaker contacts open and go out when they are closed. Begin to slowly turn the engine crankshaft clockwise.
Step 5
As soon as the light goes out, mark the position of the slider on the distributor body. Also note the position of the slider when the light comes on. Measure the length of the circular arc along the body of the breaker. To calculate the UZSK, multiply pi (3, 14) by 360 and by the diameter of the distributor body, and then divide by the measured arc length between the marks. The result will be the angle in degrees and minutes. Compare it with the recommended values in the instruction manual.
Step 6
To adjust the ignition timing (UOZ), turn the crankshaft so that the mark on its pulley coincides with the mark on the timing cover (see the operating instructions). In this case, the distributor slider should stand opposite the high-voltage wire of 1 cylinder. Connect the bulb with one wire to the wire from the distributor to the ignition coil, the other to ground. Remove the center wire from the breaker cover and lean against the ground. Loosen the bolt fixing the distributor housing. Switch on the ignition.
Step 7
Begin to turn the distributor housing clockwise until the lamp goes out. Then slowly rotate it in the opposite direction until the light turns on. As soon as the light comes on, fix the breaker housing with the bolt in this position. After making all adjustments, check the result while driving.
Step 8
Warm up the engine, accelerate to 40-50 km / h in 4th gear. With a sharp press of the gas pedal, characteristic knocking knocks should appear and a confident set of speed should begin. If there is no audible detonation, turn the distributor counterclockwise 1 division on the scale at the base of the case. If knocking knocks last more than 1-2 seconds, turn the distributor clockwise by the indicated amount. Repeat the procedure until you get a detonation, lasting 1-2 seconds.
