Correct setting of the ignition timing in the contactless ignition system makes it possible to operate the car in a comfortable environment. Otherwise, the engine does not develop its full power and fuel consumption increases. You can set up contactless ignition not only at the service station, but also on your own.
Instructions
Step 1
Set the crankshaft to a position that corresponds to an ignition timing of 5 degrees. In this case, the middle mark on its pulley should coincide with the pin on the block cover, this will mean the end of the compression stroke in the first cylinder, or top dead center (TDC). When the ignition distributor sensor is not removed from the engine, the TDC of the first cylinder can be determined by removing the distributor cover. The slider should be opposite the inner contact of the cover, which is connected by a wire to the spark plug of the first cylinder.
Step 2
If not, it is necessary to unscrew the spark plug of the first cylinder. Close the hole with a paper stopper, take the crank or ratchet wrench and turn the crankshaft. TDC will be in the right place as soon as the air pushes the plug out.
Step 3
Loosen the octane-corrector screw with a 10 key and set its scale to "0" (the middle of the scale). Take the key 10 and loosen the screw that secures the octane corrector plate. Turn the housing of the distributor sensor until the markings are aligned: the arrow on the stator and the red line on the rotor. Hold the transducer in this position and tighten the screw.
Step 4
Make sure that the slider is against the contact of the first cylinder on the distributor sensor cover. Check the order of connecting the high voltage wires of the engine cylinders. It is 1-2-4-3 when counted counterclockwise, starting from the first cylinder.
Step 5
Check in addition the correctness of setting the ignition timing when the vehicle is moving. To do this, warm up the engine to 80 degrees, accelerate the car to 60 km / h, turn on the fourth gear and sharply press the accelerator ("gas") pedal. If the detonation (the sound of which is similar to the knock of valves) disappears after appearing in 1–3 s, then the ignition moment is set correctly.
Step 6
When detonation lasts for a long time, it indicates that the ignition timing is too large. Decrease it with the octane corrector by one division. If there is no detonation, you need to increase the ignition timing, and then check again.
