Why do I get black smoke from my exhaust pipe?
Mostly experienced in cars that are turbocharged, this turbocharged acts as an exhaust-driven pipe that pumps extra air into the engine and is joined by additional fuel to give increased power. “Note that the extra fuel will only be burnt properly if enough air is supplied and that means the turbocharger has to be in good shape”
What does Balck smoke in a car mean?
Balck smoke is partially burnt diesel- basically it means the car is chucking a shed load of diesel into the bores, its not all being burnt, and is being chucked out again as soot.
