很多朋友都知道车辆在冷天启动后要怠速暖车,这样可以减少动力及传动系统的磨损,从而延长汽车的使用寿命。但是,千万不要长时间怠速热车,应配合进行行驶热车。在冷天启动车辆后,等发动机怠速稳定之后就可以低速行驶了,因为过长时间的怠速热车,除了增加耗油量和积炭外,也不利于环保。在行驶热车的过程中,千万不能高转速行驶,应保持低速行驶,发动机转速不宜超过2000r/min。待机油温度上升至正常工作温度后,再恢复到正常的开 Many of my friends are aware that the vehicle idly warms up when it starts up in cold weather, thus reducing the wear and tear on the power and driveline and thereby extending the life of the car. However, do not idle for a long time hot car, should cooperate with the hot car. After starting the vehicle in cold weather, the engine can run at a low speed after the engine idling is stable, because an idle hot car that is too long will not be environmentally friendly in addition to increasing fuel consumption and coke deposition. In the process of traveling hot car, do not drive at high speed, should keep driving at low speed, the engine speed should not exceed 2000r / min. Standby oil temperature rose to normal operating temperature, and then returned to normal open
