Black smoke from a diesel engine is caused by too much fuel in the air-fuel mixture, also called a "rich" mixture. This is generally caused by worn out fuel injectors.
Fuel is injected into diesel engines through very small holes (approximately Ø0.7mm) under very high pressure (over 1200 bar) in order to get good atomization. As the fuel flows. the hole erode, getting larger. Over time, the holes get large enough to let too much fuel through. Usually this happens in an over-the road truck around 100,000 miles.

What causes slow deceleration on a diesel engine?
Diesel engines do not engine brake like gasoline engines do, so relatively speaking, the rate of deceleration would seem to be slower.
Are diesel engines more polluted than steam engines?
Of an individual diesel engine and an individual steam engine of the same energy output the diesel engine would be less polluting. It is far more efficient. However, there are far more diesel engines than steam engines in the world today so overall diesel engines pollute more than steam engines.
Are gasoline and Diesel engines heat engines?
Yes, gasoline and diesel engines are heat engines. The energy released by the burning fuel causes the gas in the cylinders to expand and push the pistons, which in turn do work.
What causes white puffing smoke from a diesel engine?
The cause of white puffing smoke in a diesel is the crack pipe ventilator seal. Fix that it keeps the crack inside.
