Fault phenomenon of incorrect ignition timing

Improper ignition timing will lead to a series of engine failures.

Early ignition time:

(1) When the car starts, the engine turns heavy (it is difficult to start) and feels frustrated;

(2) The engine vibrates when idling, resulting in car crash;

(3) There is knocking sound when accelerating rapidly;

(4) After the car is started, the engine water temperature is high and the boiler often boils.

Ignition time is too late:

(1) The engine is stuffy, weak and even overheated. The throttle opening suddenly increases, the engine speed cannot be increased, and the fuel consumption increases;

(2) When accelerating rapidly, the exhaust pipe sometimes explodes;
