Your car is either running way too rich or the rings are worn out and your buring oil. If it is just running rich one of your sensors are out or you need a general tune up. If your rings are worn out then your engine needs rebiult. To tell if your rings are bad your cars smokey exhaust will have a blueish tint to the smoke.

What cause black smoke in the exhaust?
Black smoke is caused by the engine ~not~ burning all of its fuel. The most common cause of incomplete fuel burn is a clogged air filter, exhaust system (muffler) or injectors covered with carbon build-up. Another cause is too much fuel entering the engine to be burned due to either bad calibration or too heavy a load.

Balck smoke usually means the engine is burning rich - that is to say, more fuel is being delivered to the combustion chamber than can be ignited by the spark plugs. Keeping a good tuneup schedule and clean-up/replacement of sprak plugs will prevent, or at least minimize the black smoke under heavy acceleration.
