Like people, if the car body shakes, it actually means that your car has had a problem. Ordinary body flutter can be divided into several situations. Different flutter represents different sources of problems. Today, Xiaobian gives you popular science.

　　1. 轮胎问题

　　1. Tire problem

　　在车身颤动中，常见的就是轮胎问题，假如在行车的过程中发现车身有细微的颤动或偏移，普通是由于轮胎的均衡情况不佳，还有一种状况是轮毂发作变形，赶紧去修理厂做一个四轮定位和动均衡。

　　In the body flutter, the most common problem is the tire problem. If there is a slight flutter or deviation in the body during driving, it is usually due to poor tire balance. Another situation is that the hub is deformed. Go to the repair shop to make a four-wheel positioning and dynamic balance.

　　2.发起机积碳

　　2. Starter Carbon Deposition

　　假如节气门过脏或喷油嘴积碳过多，也会形成汽车颤动，汽车在拥堵的城市行驶会使发起机长期低转速、低负荷的状况下工作，很容易构成积碳，手动挡汽车更严重。这时分您需求清洗油路，积碳。

　　If the throttle is too dirty or the fuel injector has too much carbon deposit, it will also cause the automobile to flutter. The automobile driving in the congested city will make the engine work in the condition of low speed and low load for a long time. It is easy to form carbon deposit, and manual block the automobile is more serious. At this time, you need to clean the oil pipeline and deposit carbon.

　　3. 油、液

　　3. Oil and liquid

　　运用油品不佳的燃油、机油，防冻液液面过低会招致积碳、发起机光滑度降低，缸垫等部件的损坏，都会发作颤动。

　　Using poor fuel oil and engine oil, too low level of antifreeze liquid will lead to carbon deposition, reduce the smoothness of the engine, damage to cylinder pad and other components, will occur tremor.

　　4. 燃油标号不合理

　　4. Irrational fuel labeling

　　假如发起机发作爆震的状况，多是加错油了，不过这种状况比拟容易发作在汽油上，柴油发起机很少发作爆震问题，由于汽油抗爆性的差别，有的原来运用95号汽油的车型运用新的京标92号汽油就有细微爆震的可能。

　　If the engine has a knock, it is mostly misfueled, but this situation is comparable to easy to occur on gasoline. Diesel engine seldom has knock problem. Because of the difference of gasoline explosion resistance, some original models using 95 gasoline have the possibility of slight knock when using the new Beijing Standard 92 gasoline.
