A bad air filter can cause black smoke or bad fuel injector and maf,tp sensor
In a diesel engine, blue smoke is an indication of oil being burned. Black smoke means that there is incomplete combustion of the fuel. White smoke can be seen when raw diesel fuel is not being burned.
White smoke means water, blue/black smoke means oil, black smoke can also mean the fuel mixture is too rich.
White smoke is a coolant leak Black is a rich condition Blue is burnt oil.
Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.
Black smoke from an engine is caused by unburnt fuel.
Black smoke = excessive fuel entering the engine
yes...the lack of air would causes excessive fuel which would cause black smoke.
From engine compartment?- valve cover oil leak coolant leak-radiator/hoses from exhaust- black- too rich blue- burning oil white- blown headgasket, cracked head, engine is burning coolant
its either engine vibration,high rpm,black smoke!
The black smoke that a diesel engine blows out is fuel that is unburned. The black smoke can be caused from over-fueling, poor fuel quality, or dirty or worn fuel injectors.
Black smoke-you are burning oil, engine is worn out. White smoke-you probably have a blown head gasket. Good luck with either one, both are expensive to repair. The above answer is only partially correct. Black smoke is not oil burning. Black smoke is an overly rich fuel mixture. Blue smoke is burning oil and white smoke is coolant in the combustion chamber.
