Black smoke is very harmful for human body. In our country we can see that many vehicle throw black smoke and this pollutes our environment.Some reason of causing black smoke and some instruction to get rid from this problem are given below:-
Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. The burning of excess fuel is also referred to as, "running rich." When black smoke is noticed coming from the tailpipe, it is often coupled with the complaint of poor fuel mileage. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor but black smoke from the tailpipe is not, as a rule, a great cause for alarm. Excess fuel can leak into the cylinder if the carburetor is out of adjustment. A faulty fuel pump, a leaky fuel injector, or a failing engine computer or computer sensor can be other reasons for fuel entering the cylinder. If black smoke is present
• Check the engine oil to make sure excess fuel has not contaminated it.
• Look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated, it will have the appearance of a chocolate milkshake.
• Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil.
• Call your mechanic and advise him of what you have found.
