Different types of Exhaust Smoke Explained | Black, White, Blue

2022

Different colors of smoke usually black, blue, grey or white can appear from an exhaust from time to time, but not all of these are necessarily a cause for alarm. An occasional puff of smoke from the exhaust when accelerating likely isn't anything to worry about. Black smoke: We commonly see black smoke coming out from cars on the road. It is usually the carbon being emitted. However, there are many other reasons why this might be happening. First, your engine could be burning fuel more than the usual amounts



Black smoke
is generally a sign that the fuel-air ratio in your engine is too rich. It means that the fuel injectors are either adding too much fuel or the intake valves aren't getting enough air in. White smoke: It is also called cold smoke. It comes out of an exhaust pipe quite a normal phenomenon when warming up the cold engine. If you're seeing white exhaust smoke, it could mean two things, depending on how thick it is. If the smoke is thin, it's most likely to be steam rather than actual smoke and is caused by condensation in the exhaust system. When you start your car, the warming engine turns the condensation into steam, and the white smoke you see should disappear.


Blue Smoke:
If you're seeing blue smoke coming from your exhaust, it is likely to be caused by oil leaking into the combustion chamber and being burned with the fuel. If your car has been serviced recently or you've serviced it yourself it could be that too much oil has been put back into the system, and this excess oil is burning off. If the smoke stops after a while, then there's no problem. Or, if your car is old or has covered a large number of miles, it's pretty common for engine seals to wear and allow oil to leak into the combustion chamber.


Grey smoke:
If you think you can see grey smoke coming from your exhaust, treat it in the same way as blue smoke. It's probably caused by your car burning of transmission fluid or a faulty turbocharger, which may be a very common reason with engines emitting grey smoke. Moreover, another cause of gray smoke can be a jammed PCV valve. --- Time Stamp -- 00:00
