General method of judging faults
When the engine is working, if there is an abnormal phenomenon, we should conduct a thorough investigation, find out the fault situation, analyze and judge carefully, and find out the location and cause of the fault. This requires us to be good at using relevant principles and structural knowledge, analyze and reason, and find out the essence through the phenomenon. Generally, the cause of the fault is judged according to the following principles:
1 When there is an abnormal phenomenon in the operation of the engine, you can use "look, listen, touch, smell" and other comprehensive methods to judge which part or system has a fault.
"Look" - observe the readings of each instrument, the exhaust smoke color, and the changes in water, gas, and oil;
"Listen" - use a slender metal rod or a wooden handle screwdriver as a "stethoscope" to touch the corresponding part of the engine surface to "listen" to the sound emitted by the moving parts and its changes. ;
"Touch" - check the working conditions of parts such as the valve mechanism and the vibration of the engine with your fingers;
"Smell" - use your sense of smell to show whether there is any abnormal smell in the engine.
2 When the engine suddenly fails or the cause of the failure has been determined, and the failure will affect the normal operation of the engine, it should be stopped and checked in time. For faults that cannot be immediately identified, the engine can be operated at low speed and no-load, and then observed and analyzed to find out the cause to avoid a larger accident.
3 When it is judged to be a major fault or the engine suddenly stops naturally, it should be disassembled and inspected and maintained in time.
Correctly analyzing and judging the cause of engine failure is an important and meticulous work. It should not be disassembled and repaired randomly before the cause of the fault is clarified. This will not only fail to eliminate the fault, but may also cause new faults when reinstalling.
