Abstract
This paper describes four areas: engine common faults, petrol injection pressure test conditions, cold starting problems troubleshooting, troubleshooting idle condition; example jitter Troubleshooting engine, including accidental short circuit power line injector Engine shaking, cold oil pump causing the engine oil pressure is too high trembling; winter cold state of the common faults; final narrative of the diesel engine fault diagnosis, by observing the exhaust smoke color the sound, feel the vibration and temperature, observation instrument instructions, check crankcase ventilation, smell the smells, the dissolution of the fuel pump, fuel supply function test to determine their fault.
