Engine ignition timing inspection and adjustment

The engine can work properly, and ignition timing has a direct relationship. Even if the ignition timing error is small, the fuel consumption is increased and the power is decreased, so the ignition timing must be accurately corrected. The timing is usually used to check and adjust the ignition timing, as follows: 1. First check and adjust the octane modifier to the standard position. Each line of the reticle indicates 1 °, the alignment should be aligned to align the center line with the alignment mark, and adjust the contact gap of the breaker. 2. Ignition timing lamp of the three wires in the two, respectively, and battery positive and negative poles connected to the other root folder in the first high-voltage line jacket (due to the point of the timing lamp of different forms, the connection method is also Some differences). 3. Let the engine run at idle speed, heat up to 80 ℃. 4. With the ignition timing light flashing engraved on the engine crankshaft pulley or flywheel timing mark, observe the engine ignition advance angle, whenever the ignition timing mark aligned with the timing indicator, the timing light flashing, flashing Synchronized with alignment, the scale between the timing mark on the crankshaft pulley and the pointer on the timing gear cover can be clearly observed by the flashing light. When the timing mark moves toward the opposite direction of engine rotation, it indicates that the ignition is advanced, on the contrary, it indicates the ignition delay. 5. Loosen the fixing screws of the distributor bracket and turn the distributor housing (for example, if the ignition time is too late, turn counterclockwise as the ignition timing is too early and turn clockwise), adjust the ignition time to the specified ignition time , And fixed distributor. It must be noted: the engine to ensure slow idle operation, or ignition early adjustment device work, will affect the correctness of the adjustment.
