Does Keeping the Engine Idling for a Long Time Damage the Car?
1 Answers
Keeping the engine idling for a long time can damage the car, with effects including shortening the engine's lifespan; easily burning out the three-way catalytic converter; increasing engine carbon deposits; damaging the vehicle's electronic systems; causing fuel injector failures; and increasing the risk of freeze blockage. Engine idling is an operational condition where the engine runs without load, only overcoming the frictional resistance of internal components, without delivering power externally, maintaining a lower stable operating speed. The idle speed can be adjusted by altering the throttle opening and the idle fuel supply. Adjusting the idle speed must be done under normal conditions, including normal engine temperature, appropriate valve clearance, normal ignition system condition, good sealing of all pipelines, fully open choke valve, and tightly closed throttle. During adjustment, first unscrew the throttle opening adjustment screw to achieve the lowest stable engine speed.
