What are the common faults of diesel engines?

[LaJordan]

Common faults of diesel engines are as follows: 1. Difficulty in starting the diesel engine: mainly includes starting faults such as difficulty in starting the diesel engine at normal temperature and cold starting difficulties. 2. Unstable idle speed: mainly refers to idle speed faults such as unstable idle speed, no idle speed, and idle speed fluctuation. 3. Unstable operation under medium and small load conditions: the engine is prone to stalling, individual cylinders work intermittently, and power output is unstable. 4. Insufficient power under heavy load: the diesel engine is weak under high-speed and high-load conditions, and the car has insufficient power such as weak acceleration. 5. High fuel consumption of diesel engine: it is found that the car consumes too much fuel during use, and the fuel consumption per 100 kilometers increases significantly during long-distance travel. 6. The diesel engine does not stop after cutting off the fuel: the engine continues to run after being turned off; it still does not stop after repeated shutdown attempts.
