Black smoke, from any diesel, is the result of partially burned fuel. Overfueling will cause black smoke.
In a diesel engine, blue smoke is an indication of oil being burned. Black smoke means that there is incomplete combustion of the fuel. White smoke can be seen when raw diesel fuel is not being burned.
its a diesel, you will see black smoke alot.
The black smoke that a diesel engine blows out is fuel that is unburned. The black smoke can be caused from over-fueling, poor fuel quality, or dirty or worn fuel injectors.
Unburnt fuel
Turn down the fuel getting to the injectors.

you can use chips, power mods, and smoke switches.
to make a diesel blow black smoke is usually done by turning up the fuel pump.all this accomplishes is to much fuel and the black smoke created is mostly un burnt fuel that is being wasted
the black smoke is unburnt fuel. you need a leaner air/fuel mixture.
Only on cold startup (diesel engine) it can be normal to get little black smoke, as long as it doesn't continue. If it continues after warm up that could indicate engine wear. I'd recommend a mechanical inspection. The newer common rail diesels though are generally cleaner burning than older engines.
