What does white smoke from diesel engine mean?

What causes black smoke from diesel exhaust?
If your vehicle runs on diesel, then over-fueling may be the primary cause of black smoke coming out of your exhaust pipe. When the fuel injector of a heavy duty diesel engine wears out, it causes the nozzle hole to enlarge or the injector needle to erode. This allows excess fuel to enter into the engine’s combustion chamber.
