If an engine is running rich, it is receiving and burning too much fuel and that will yield black smoke. If an engine is somehow burning oil, that will yield white smoke.
its probably burning oil, if the smoke is white. if the smoke is black, it means its running rich. if the smoke is white, you have serious internal engine problems
Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.
Sensors do not make an engine smoke, unless one is causing the engine to run rich.=Black smoke = Overly rich fuel/air mixture.==Blue smoke = Burning oil.==White smoke = Coolant entering the combustion chamber.==The O2 Sensor would be suspect if it is running rich.=
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.
Blue smoke = Burning oil Black Smoke = Overly rich fuel/air mixture White Smoke = Coolant entering the combustion chamberBlue smoke = Burning oil Black Smoke = Overly rich fuel/air mixture White Smoke = Coolant entering the combustion chamber
A diesel puts out Black smoke when it is running Too Rich. Blue means Burning Oil, white is a Coolant leak (Blown head gasket). Black actually means it's wasting Fuel.
White smoke = Coolant leak, head gasket is the likely culprit. Blue smoke = Engine burning oil. Black smoke = Engine running too rich, wasting fuel.
The engine is burning rich. Clean or replace the spark plug and air filter. If you still get black smoke, close (rotate clockwise) the carburetor needle valve 1/8 turn for a leaner mixture.
The presence of black smoke from exhaust when engine is first fired.That sign could also be an engine running too rich.
Black smoke is a indication of an overly rich Fuel/Air mixture. Blue smoke is oil burning.
AnswerOne potential cause is too much gas. It may be running "rich". Your car may also be burning a little oil. White smoke is usually water or antifreeze. If you are loosing coolant from the radiator, it's probably a blown head gasket. If not, it is just condensation in the exhaust pipe that is evaporating as the pipes heat up. If the car is running too rich, the unburned gas will cause black smoke and burning oil smoke will be blue.
