大众新帕萨特冷车启动抖动

　　冷启动时车子抖是汽油车的普遍毛病。冷启动或者空挡候车的抖动现象最根本原因是汽缸内燃烧不好。燃烧不好，车子提供的动力性就不够，车子就发生抖动。点火能量偏低车子冷启动时面临的第一个问题就是低温，发动机内的温度不够，燃油和润滑油的温度都不够，所以在冷启动时应该多喷油以满足动力性的要求。火花塞的间隙越大，点火能量就越小。低温时燃油雾化不好，燃油需要更高的点火能量，车子长时间使用，火花塞的点火间隙容易变大，导致点火能量下降，从而影响动力性，使车子发生抖动。另外，点火线圈老化、火花塞的高压线老化或者漏电，同样可以导致点火能量降低。因此，出现冷车启动抖动的情况要及时检查维修，以免对发动机造成更大损害。

　　汽车在冷车启动的时候出现抖动甚至熄火现象，说明汽车已经出现了严重的积碳现象，需要及时检查节气门、火花塞、点火线圈等零部件的使用情况，必要的时候进行更换和清洁。汽车的冷启动是指在发动机水温低的情况下启动汽车，在发动机温度正常情况下连续几次启动，发动机都可以顺利启动，说明电瓶状况良好。

　　当发动机转速逐步下降，需要及时充电，注意电瓶的检测和保养，对汽车能启动时有益处。一般发动机抖动还会出现敲缸现象，会伴着活塞和缸壁出现严重磨损的现象，还会出现异常的沉闷的敲击声。汽车在冷启动的时候出现抖动现象，如果在冬天则属于常见的现象，不需要紧张。

　　【英文介绍/For English】：

　　Car shaking during cold start is a common problem with gasoline vehicles. The most fundamental reason for the shaking phenomenon of cold start or neutral waiting is that the combustion in the cylinder is not good. If the combustion is not good, the power provided by the car is not enough, and the car shakes. Low ignition energy. The first problem that the car faces when it is cold started is low temperature. The temperature in the engine is not enough, and the temperature of the fuel and lubricating oil is not enough. Therefore, more fuel should be injected during cold start to meet the power requirements. The larger the spark plug gap, the less ignition energy. The fuel atomization is not good at low temperature, the fuel needs higher ignition energy, and the ignition gap of the spark plug is easy to become larger when the car is used for a long time, resulting in a decrease in the ignition energy, which affects the power performance and makes the car shake. In addition, the aging of the ignition coil, the aging of the high-voltage wire of the spark plug or the leakage of electricity can also lead to a reduction in the ignition energy. Therefore, in the case of cold car start-up jitter, it is necessary to check and repair in time to avoid greater damage to the engine.
