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.

Why does my diesel produce black smoke?
Under heavy acceleration all diesels produce black smoke. It's a product of waste fuel being exited via the exhaust pipe and is a sign of inefficiency. Older diesels also produce black smoke under "normal" conditions and this also a cause of unspent fuel, but mainly because of age.

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.

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.

Usually a lack of spark or fuel would cause this. Most common is a coil pack issue. (Thats where I would look first).
What causes 2007 mazdaspeed3 to studder during heavy acceleration but not under slow acceleration?
Your cam driven fuel pump is unable to keep up with the sudden demand of fuel necessary under heavy acceleration.I would get that pump replaced, if you have any aftermarket engine parts you should consider an up graded fuel pump.Do not overlook this problem, doing so could cause your engine to blow
How the exhaust temperature of Heavy Diesel engine is Controlled?
The main reason for exhaust temprature is the problem with the injectors.the unburnt fuel from the combustion chamber flows to the exhaust manifold while engine works.This unburnt fuel burns in the exhaust manifold burns and causes high exhaust temprature.
Why would a 1992 Mercury blow black smoke?
Black smoke is caused by an over rich mixture and normally occurs whenever the engine is working hard. Like going up a steep grade, being loaded heavy or during heavy acceleration. More black smoke can be observed when the vehicle is operated at higher altitudes because the air is thinner. A dirty air filter is also another cause of excessive black smoke. If black smoke is noticed while the engine is idling at low altitude or under normal driving conditions this condition should be diagnosed a.s.a.p. to prevent engine damage. bad rings or busted pisten you need anew motor
