Usually on the road，We often see other people’s car exhaust pipes smoke out，Sometimes it is white smoke，Sometimes it is black or even blue，Many people are a little confused，Why is it different in the same color?

Actually，This is learned，Different exhaust colors represent different causes，If there is a color of smoke, continue to let it go，I am afraid that the amount of the car is getting deeper and deeper。Today，Let's take a look at how the three colors of these three colors of the car are caused by。

Baiyan

The exhaust tube dripping seabet iowhite smoke is a very common situation，Especially when the car just started the car in winter。

Usually，Whatever the reason，The white smoke we see is formed by water vapor，When the cold car starts in winter，Due to the low external temperature，The discharge of water vapor generated after the engine burns will change the white smoke we see，This situation is the most common，and it is very short，It can be seen as the same principle with our mouth in winter。

But if the phenomenon of white smoke is continuous and stronger，That is abnormal，Explain that the engine is in the problem，You need to check whether there are water such as coolant inside the engine to enter，or the amount of gasoline with the additional gasoline is too high，

Patto Blue Smoke

If the exhaust pipe is dripping blue smoke, it means that the car has failed,When the engine oil enters the combustion room to participate in the burning room, the phenomenon of blue smoke will occur。

When the oil burning oil appears，The owner must pay attention to，Because at this time, maybe your car engine has excessive oil surface too high、Valley oil seal aging、Pistons and cylinder walls are too large，Must be maintained in time，To avoid the decrease in lubrication effect due to insufficient oil volume，Pull cylinder，and form a large amount of carbon deposits。

Black smoke

I believe many people have seen the exhaust pipe and the black smoke，Especially for some old cars with long years of seabet mylong life。The exhaust pipe is dark smoke. Generally speaking, it is too strong，The engine burning is not sufficient，That is, insufficient air intake，For too much fuel，The engine is not enough during the combustion，Gasoline is not completely burned，Form a large amount of carbon particles at high temperature，excludes & quot; carbon smoke & quot;，That is the black smoke we see。

There are many reasons that cause this phenomenon，Location sensor like a throttle door，Air flow meter，Oxygen sensors and other sensors that fail to fail。If not repaired in time，It takes more oil，Easy to form carbon，Moreover, it is more serious for air pollution。

This can be seen，Smokes from different colors of exhaust pipes are caused by different reasons，All related to the engine burning room situation，When we find that the exhaust is not right，You can analyze the cause of the faulty through the color that is discharged，Popular medicine。
