Black smoke is unburned gasoline. Possibly your o2 sensor has failed and not sending a signal to the ECU, or the wrong signal, that is what controls the fuel/air ratio and your car is running very rich

Another possible cause is a bad fuel regulator. The increased fuel pressure squirts extra fuel into the cylinders.

Did this start suddenly or has it been happening a long time? If it has been a long while, it could be worn piston rings and that could be burning oil.
