Q: Engine shakes when heat is on

asked byMarch 02, 2017

我有2001年的巡洋舰。发动机一次摇动/振动大约2-3秒钟,只有当我打开热量并让汽车闲置时,才能在寒冷开始。这样做一段时间,直到汽车被“热身”为止。如果我在冷启动时让它闲置在公园位置时会闲置时,那就不会这样做。原因是什么?谢谢。

Hi There, This may potentially be a result of the change in heat in the coolant that results when turning on the heater while the car is still warming up. As you may know, when the car is first started when cold, thecoolant temperature sensor读取冷却液的温度,并将此信息传递给ECU。TE ECU使用此信息来调整空气/燃料比(增加更多燃料),因为由于发动机在较冷的温度下空气密度的差异,发动机需要更多的燃料才能运行。我建议让您的机电专业人士来您的位置来看看您的车辆。万博体育入口
