Why did my Wuling Glory Cam get a new Jiangling power engine? After running 3000 kilometers, I heard the engine turn.

Because in winter, the engine oil will become more viscous and difficult to flow, resulting in abnormal engine noise. When using the car at ordinary times, if the oil level is too low, add the engine oil in time. Don't let the engine run at too high a speed when the engine has just started and has not reached the normal working temperature.

In general, the idle speed of the engine is determined, and the specific level depends on the specific vehicle type adjustment. Under normal circumstances, high idle speed will lead to relatively high fuel consumption, but low idle speed will lead to engine jitter or even flameout.

Throttle oil accumulation and throttle carbon accumulation, and the air inlet is too dirty;

Blocked air intake will cause idling, and there is carbon deposit or engine oil in the throttle, which is the most common cause of unstable idling. Due to carbon deposition, the throttle will affect the opening and air intake, which will make the engine speed fluctuate after the car is started, which is very unstable and accompanied by strong jitter.

The throttle valve has serious oil storage or carbon deposition, including unclean air intake, which makes it difficult to start the car in cold weather. When the throttle is dirty, it needs to be cleaned, and the throttle cleaning itself is also a routine maintenance item.
