Black smoke from an engine is caused by unburnt fuel.

Black smoke in your exhaust is a sign of your car burning oil. You should have a qualified mechanic inspect your car and make the proper adjustments.

white smoke can be either your car overheating, or smoke from an electrical issue

The most probable cause is combustion of a rich mixture of fuel.

Black smoke coming out of the exhaust of a car is usually due to oil being burned in the engine's cylinders. This can be caused by a worn piston ring or rings.

No it shouldnt, it will however make it harder for the car to start... typically, black smoke from the tail pipe means you have an oil leak somewhere

one of the causes of all three symptoms is a bad fuel injector

the environment causes cancer because the car pollute the air also when people smoke the smoke goes in there lungs and that causes second hand smoke

because its a terrible car mad , if the smoke is black the car wants to die , take it out of its miysery

They will definitely spark only if they are connected incorrectly meaning one car you put black on black red on red and the other car you put red on black and black on red a BIG NO NO

Black smoke usually indicates an overly rich fuel/air mixture. In other words the engine is getting too much fuel or it is not being burned properly. Blue smoke is oil burning. White smoke is coolant in the combustion chamber.

Blue smoke = excessive motor oil. Black smoke = excessive fuel. White smoke = engine coolant

Possibly if there is some water in the fuel. You will also see black smoke if the fuel/air mixture is too rich. White smoke is coolant in the combustion chamber and blue smoke is oil burning.

a blown head gasket most likely.

The color of the smoke will help identify the problem. Blue smoke is engine or transmission oil. Black smoke, excess fuel. White smoke, engine coolant.

It is the car running too rich. or the car is using more gas than air.

Blue smoke is oil burning, White is steam(water), Black smoke is unburnt fuel.

your car leaked oil into the combustion chamber. blue smoke= burnt oil, the loss of power is from inproper combustion

it can, mine is bad and i will get smoke from time to time.

You should have your car checked out at a shop! I wouldn't be driving around with such strange car troubles.

AnswerThere are several possible answers to what makes a car smoke. If the smoke is blue-black the engine is burning oil. This could be caused by worn rings or valve guides. If the smoke is gray black it is caused by a to rich gas mixture. This could be caused by a malfunctioning choke or injector, oxygen sensor, or other fuel related equipment. If the smoke is gray white it could be a blown head gasket or cracked block, allowing coolant to get into the exhaust system. Other causes of smoking could be an oil leak that is dripping on to the exhaust pipe or muffler.

White smoke is usually vaporized coolant. You may have a blown gasket or a crack somewhere.

Blue smoke, burning oil. (tired) White smoke, burning coolant. (bad head gasket) Black smoke, excess gasoline (flooding).
