一例丰田卡罗拉发动机怠速发抖故障诊断排除

汽车发动机怠速抖动是在维修中常碰到的故障现象,故障发生时往往在发动机怠速工况时产生低频率异常振动现象。出现抖动时,可以通过观察发现发动机的横向摆动明显加大,噪声加大;并往往伴随怠速不稳,使车内的驾乘人员感到不舒适,而随着加大油门使发动机转速升高后,发动机抖动现象便减弱或消失。由于发动机怠速抖动会影响发动机的性能,降低其可靠性与使用寿命,增加了功率损耗。如不及时维修,会使发动机性能进一步恶化,有可能导致更大的故障。

Case of Toyota Corolla Engine Idling Shaking Troubleshooting

The car engine idle shake failure phenomena encountered in maintenance often,when a fault occurs often in the engine idling condition abnormal low-frequency vibration phenomenon.Jitter occurs,can be observed significantly increased the horizontal swing of the engine noise increase;and is often accompanied by unstable idle,the car occupants feel uncomfortable,and with the throttle so the engine speed increases engine jitter will weaken or disappear.Jitter will affect the performance of the engine due to engine idling,reducing its reliability and service life,an increase of power loss.If not promptly repair,and make the engine performance further deterioration may lead to greater failure.
