摘 要
本文敘述了四個(gè)方面的問題：發(fā)動(dòng)機(jī)常見故障，汽油壓力與噴射狀況的檢測(cè)、冷起動(dòng)困難故障排除、怠速工況故障排除；舉例說明了發(fā)動(dòng)機(jī)抖動(dòng)故障的排除，包括噴油嘴電源線偶發(fā)短路引起發(fā)動(dòng)機(jī)發(fā)抖，機(jī)油泵冷車輸油壓力過高引起發(fā)動(dòng)機(jī)發(fā)抖；冬季冷車狀態(tài)的常見故障，發(fā)動(dòng)機(jī)高溫故障分析和排除。

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.
