In order for the dynamics of your car to be at its best, the operating fuel consumption is minimal, and the resource is maximized, it is necessary to properly adjust the ignition. For vehicles with a classic contact ignition system, this procedure consists of three steps.
1) The angle of the closed state of the contacts is regulated, for which it is necessary:
- remove the ignition distributor cover;
- remove the tubercle, which is usually formed on a movable contact;
- clean the distributor contacts with a file;
- check the tightness of the contacts to each other along their entire plane;
- if necessary, adjust the fit by bending the fixed contact;
- turning the crankshaft by the ratchet, using a special key or starting handle, set the maximum distance between the contacts;
- unscrew the screw that keeps the contact group from moving and, using a flat probe with a thickness of four tenths of a millimeter, set the gap between the contacts so that the probe moves in it with little effort;
- tighten the screw securing the position of the contact block.
2) The ignition timing is adjusted. The easiest way to adjust the car ignition is with a stroboscope. This is done in this way:
- any car stroboscope, preferably powered from a 12 volt network, connect to the corresponding terminals of the battery;
- put the signal sensor on the high-voltage wire that goes to the spark plug of the first cylinder;
- disconnect the vacuum corrector hose from the distributor and plug it off;
- start the engine and warm it up to operating temperature;
- achieve stable idle speed;
- loosen the bolt holding the distributor from turning;
- direct the light of the strobe lamp to the crankshaft pulley so that the marks on the pulley and the mark on the front cover of the gas distribution mechanism are visible;
- turn the distributor housing clockwise or counterclockwise until the position of the ignition mark on the crankshaft pulley is against the mark on the front timing cover;
- having set the appropriate position of the marks, fix the distributor body by tightening the fixing bolt.
3) Check the adjustment result in dynamics:
- on a horizontal section, accelerate the car to 50 km / h;
- press the gas pedal sharply, if the knocking knocks are not more than two seconds, the ignition is set correctly.
