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. 輪胎問題

　　1. Tire problem

　　在車身顫動中，常見的就是輪胎問題，假如在行車的過程中發現車身有細微的顫動或偏移，普通是由于輪胎的均衡情況不佳，還有一種狀況是輪轂發作變形，趕緊去修理廠做一個四輪定位和動均衡。

　　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.發起機積碳

　　2. Starter Carbon Deposition

　　假如節氣門過臟或噴油嘴積碳過多，也會形成汽車顫動，汽車在擁堵的城市行駛會使發起機長期低轉速、低負荷的狀況下工作，很容易構成積碳，手動擋汽車更嚴重。這時分您需求清洗油路，積碳。

　　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

　　運用油品不佳的燃油、機油，防凍液液面過低會招致積碳、發起機光滑度降低，缸墊等部件的損壞，都會發作顫動。

　　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. 燃油標號不合理

　　4. Irrational fuel labeling

　　假如發起機發作爆震的狀況，多是加錯油了，不過這種狀況比擬容易發作在汽油上，柴油發起機很少發作爆震問題，由于汽油抗爆性的差別，有的原來運用95號汽油的車型運用新的京標92號汽油就有細微爆震的可能。

　　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.
