We can not be seen under normal temperature automotive exhaust

If the color appears automobile exhaust

That car is definitely a problem

I'll teach you today

How to analyze the failure by car exhaust color

1. exhaust pipe to take blue smoke Failure Analysis: This is a significant phenomenon of burning oil.

Possible causes and solutions: piston ring failure. Such piston displacement, damage, replacement of piston rings need to disassemble the engine.

Valve seal leakage. Oil seep from the cylinder valve seal the leaks, replace the valve seals.

Cylinder head gasket ablation. Oil seep from the damaged cylinder head gasket cylinder, replacing the engine cylinder pad.

Water separator failure. Is the oil-water separator for separating crankcase oil vapor, oil vapor will be damaged if directly into the cylinder, replacing water separator.

2. The exhaust black smoke Fault Analysis: exhaust black smoke, described mixture is too thick, due to incomplete combustion. That is, in-cylinder gasoline content of the mixture gas beyond the normal level.

Possible causes and solutions: ? The air filter is dirty, inadequate intake, remove the filter, use a damp cloth to wipe down just fine, some of the dust in general is, as long as the center is clean enough, there is the feed gas engine.

Bad fuel oil, recommended to find PetroChina, Sinopec gas station to refuel.

Without EFI car carburetor, possibly also an oxygen sensor in the exhaust pipe of the contamination, can not provide the correct information to the computer with the air, to detect the maintenance alone.

? Individual cylinders not working (short cylinder) or late ignition, may be defective spark plug or ignition timing control problems.

In fact, more than just a more common part of possibilities, after all the various systems of the engine it is also a large number of component parts, the reason is impossible not and will and all, specific reasons should be combined with the actual situation.

Exhaust black smoke black smoke whenever the vehicle can not be ignored, a long time will inevitably produce large amounts of carbon, increased fuel consumption, the impact tightness of the combustion chamber, resulting in decreased engine power, resulting in decreased vehicle power, sluggish acceleration, boring. And exacerbate the wear between components, greatly reducing the life of the engine, and it is very terrible thing.

Engine black smoke also often accompanied by decline in engine power, performance degradation and other economic problems, driving comfort also has a significant impact. And exhaust emissions of non-compliance, would go even vehicle inspection. So if the engine black smoke appeared, but also early detection, early maintenance in order to avoid more serious consequences.

No fault: 3. Analysis of white smoke exhaust pipe failure.

Possible causes and solutions: This situation is quite common when the weather is too cold or too low engine temperature, fuel combustion to generate steam and mist will produce white smoke after exposure, is a normal phenomenon. This phenomenon in the winter or rainy season, when the car just more common, once the engine temperature increases, the white smoke would disappear, do not worry.
