Changhe Freda idling jitter flameout (what about Jimny engine jitter)

There are seven reasons: insufficient fuel supply in the fuel system; The mixture is too thin or too thick, and the high-voltage spark is weak; A single cylinder does not work; Ignition timing error; Air leakage in the air intake system; Cold idle speed adjustment fault; Time-sensitive valve failure.

Idle speed is a working state of the car, which means that the engine runs in neutral position. The engine speed at idle speed is called idle speed. You can adjust the idle speed by adjusting the size of the throttle. Idle speed means that the engine is "not working".

When the engine is running, if the accelerator pedal is completely released, the engine will idle. When adjusting the idle speed, the speed should not suddenly rise or fall, otherwise it will cause early wear and tear to the engine, so it is best to go to the automobile maintenance department for adjustment.

Idle speed means that the engine runs with no load, and it only needs to overcome the friction resistance of its internal parts and does not output power. The lowest speed to keep the engine running stably is called idle speed, which is one of the five basic working conditions of the engine. Good engine idle speed is generally 550-800 rpm.

Idle speed can be adjusted by adjusting throttle opening and idling oil supply. Generally speaking, idle speed is the lowest speed at which the engine does not shake within the idle speed range and has good acceleration performance.
