Diesel engines may have various faults. In order to ensure the normal operation of diesel engines, it is crucial to diagnose the cause of the fault in a timely and accurate manner：
1. Observation method. Observation method is the most basic fault diagnosis method. By observing the operating status of the diesel engine, some obvious abnormal phenomena can be found.

2.Auscultation method. Auscultation method is a method of judging the cause of the fault by listening to the abnormal sounds produced by the diesel engine during operation. Different types of diesel engines will make different sounds during operation, such as knocking, roaring, hoarseness, etc. By analyzing these sounds, it can be preliminarily judged whether the diesel engine has a fault.

3.Touch method. The touch method is a method of judging the cause of the fault by touching the surface of the diesel engine. When checking the diesel engine, you can touch the engine housing, bearings, belts and other parts with your hands to feel their temperature, vibration, etc.

4. Instrument detection method. The instrument detection method is a method of using professional detection equipment to detect diesel engines. Modern diesel engines are usually equipped with various sensors, monitors and other instruments that can monitor the operating parameters of the diesel engine in real time.

5. Fuel system detection method. The fuel system detection method is a method of determining whether there is a fault in the diesel engine by checking the fuel system. Faults in the fuel system may cause problems such as unstable operation and insufficient power of the diesel engine.

6. Lubrication system detection method. The lubrication system detection method is a method of determining whether there is a fault in the diesel engine by checking the lubrication system. Faults in the lubrication system may cause problems such as increased wear and power reduction of the diesel engine.
