怠速是指发动机无对外输出功率的工况,汽车发动机怠速不稳是一种常见的故障现象,然而随着汽车电控技术的发展,发动机怠速不稳更加复杂,灵活运用理论知识进行分析并利用先进的诊断设备对发动机故障进行诊断以及维修经验的积累,排除发动机怠速不稳的现象就少能走弯路,维修诊断的效率就能提高。
Idle speed refers to the engine without external output power conditions, the engine idling instability is a common phenomenon, however, with the development of automotive electronic control technology, the engine idling instability is more complex, the use of theoretical knowledge to make flexible analysis and use Advanced diagnostic equipment to diagnose the engine failure and the accumulation of maintenance experience to rule out the phenomenon of engine idle instability can detour less, the efficiency of maintenance diagnosis can be improved.
