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、缺缸式抖動：

1. Lack of cylinder shaking:

市面上跑的小汽車百分之九十都是四缸機。缺缸故名思義就是有一個缸或者多個缸不工作，這種故障都比較好查。四個缸如果有一個缸不工作就抖的很厲害，多個缸不工作幾乎就不能著車。這時我們可以借助汽車診斷儀輕松找到問題所在，診斷儀的確能給我們帶來很大的方便，但有時條件不允許或者說沒有診斷儀我們該如何診斷呢？像有些車必須要用專用軟件，比如大眾的iods. 一個軟件就要大幾百上千塊，每個診斷軟件都配齊不是所有修理店都能消費得起。

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.

大家可以用斷缸法判斷到底是哪個缸不工作了 ！

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

操作方法就是：先啟動發(fā)動機，再分別拔四個缸點火線圈插頭或噴油嘴插頭，拔了插頭后有明顯反應(yīng)的說明此缸工作良好，否則就是工作不良。診斷出來具體是哪缸的問題之后再用對調(diào)法判斷是哪個零部件出了問題。如果是一缸不工作或者工作不良，我們可以將一缸的點火線圈、火花塞和噴油嘴分別和二缸的對換，要是故障轉(zhuǎn)移到二缸就能準(zhǔn)確判斷此零部件損壞，若是按此方法還是沒查出來就只能測缸壓了，測缸壓的方法在這里就不過多的解釋了。

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、積碳過多導(dǎo)致發(fā)動機的抖動

2. Excessive carbon deposition causes engine jitter

一般來說發(fā)動機正常保養(yǎng)，節(jié)氣門、噴油嘴、進(jìn)氣系統(tǒng)都是兩萬公里清洗一次。若長時間不按時清理積碳，冷啟動時噴油嘴噴出來的汽油會被積碳吸收，積碳過多就會導(dǎo)致汽車發(fā)動機怠速發(fā)抖，冷車啟動困難，轉(zhuǎn)速忽高忽低。所以說按時清理積碳只有好處沒有壞處。

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.

還有油壓不足也會引起發(fā)動機抖動?？傊畬?dǎo)致發(fā)動機抖動的原因還有好多種，在這只舉例了一小部分。愛車一旦出現(xiàn)抖動一定趁早處理故障，一直拖著不管會導(dǎo)致發(fā)動機費油和機腳及其他零部件損壞。

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.
