Engine shaking is a very common vehicle fault. There are various ways to shiver, such as: shivering in cold car, shaking in car, shaking in idling, shaking in driving process, regular intermittent shaking, etc., which can make you doubt your life. Here are some examples for your analysis

1、缺缸式抖动：

1. Lack of cylinder shaking:

市面上跑的小汽车百分之九十都是四缸机。缺缸故名思义就是有一个缸或者多个缸不工作，这种故障都比较好查。四个缸如果有一个缸不工作就抖的很厉害，多个缸不工作几乎就不能着车。这时我们可以借助汽车诊断仪轻松找到问题所在，诊断仪的确能给我们带来很大的方便，但有时条件不允许或者说没有诊断仪我们该如何诊断呢？像有些车必须要用专用软件，比如大众的iods. 一个软件就要大几百上千块，每个诊断软件都配齐不是所有修理店都能消费得起。

Ninety percent of the cars on the market are four cylinder engines. Lack of cylinder, so called Si Yi, is that one or more cylinders do not work. This kind of fault is easier to check. If one of the four cylinders doesn't work, it will shake badly. If more than one cylinder doesn't work, you can hardly get on the car. At this time, we can easily find the problem with the help of the automobile diagnostic instrument. The diagnostic instrument can really bring us great convenience, but sometimes the conditions are not allowed or there is no diagnostic instrument, how can we diagnose? For example, some cars have to use special software, such as VW's iods. A software costs hundreds or thousands of yuan, and each diagnostic software is complete. Not all repair shops can afford it.

大家可以用断缸法判断到底是哪个缸不工作了 ！

You can use the cylinder breaking method to determine which cylinder is not working!

操作方法就是：先启动发动机，再分别拔四个缸点火线圈插头或喷油嘴插头，拔了插头后有明显反应的说明此缸工作良好，否则就是工作不良。诊断出来具体是哪缸的问题之后再用对调法判断是哪个零部件出了问题。如果是一缸不工作或者工作不良，我们可以将一缸的点火线圈、火花塞和喷油嘴分别和二缸的对换，要是故障转移到二缸就能准确判断此零部件损坏，若是按此方法还是没查出来就只能测缸压了，测缸压的方法在这里就不过多的解释了。

The operation method is: start the engine first, and then pull out the ignition coil plug or fuel injection nozzle plug of four cylinders respectively. If there is obvious reaction after pulling out the plug, it means that the cylinder is working well, otherwise, it is not working well. After diagnosing the specific cylinder problem, use the method of exchange to determine which parts are in trouble. If the first cylinder does not work or does not work well, we can exchange the ignition coil, spark plug and fuel injection nozzle of cylinder 1 with cylinder 2 respectively. If the fault is transferred to cylinder 2, the damage of this part can be accurately judged. If it is still not found out by this method, only the cylinder pressure can be measured. The method of measuring cylinder pressure is not explained here.

2、积碳过多导致发动机的抖动

2. Excessive carbon deposition causes engine jitter

一般来说发动机正常保养，节气门、喷油嘴、进气系统都是两万清洗一次。若长时间不按时清理积碳，冷启动时喷油嘴喷出来的汽油会被积碳吸收，积碳过多就会导致汽车发动机怠速发抖，冷车启动困难，转速忽高忽低。所以说按时清理积碳只有好处没有坏处。

Generally speaking, the throttle valve, fuel injection nozzle and air intake system are cleaned every 20000 km. If the carbon deposit is not cleaned up on time for a long time, the gasoline injected from the fuel injection nozzle during cold start will be absorbed by the carbon deposit. Excessive carbon deposition will cause the automobile engine to vibrate at idle speed, and it is difficult to start the car in cold state, and the rotating speed will be high or low. So cleaning up carbon deposits on time is only good, not bad.

还有油压不足也会引起发动机抖动。总之导致发动机抖动的原因还有好多种，在这只举例了一小部分。爱车一旦出现抖动一定趁早处理故障，一直拖着不管会导致发动机费油和机脚及其他零部件损坏。

There is also a lack of oil pressure will cause engine jitter. In short, there are many reasons for the engine jitter, and only a small part is given here. Once your car shakes, you must deal with the fault as soon as possible. If you drag it all the time, it will lead to fuel consumption of the engine and damage of the feet and other parts.
