Actually there are lot of type of smoke exhuast. I will sahre what i know.

Blue smoke: Blue smoke means when the engine is burning oil.

White smoke: It means when th engine is burning coolant or transmission fluid.

Black smoke: If you have a diesel engine, then the black smoke is only because of the old engine. But if you notice black smoke in gasoline engine, then the fuel injector is leaking or there is too much fuel pressure.
