This sounds like you are experiencing a "runaway" condition where the engine is either burning fuel or oil in an "Uncontrolled" manner.
I HIGHLY recommend to NOT drive it and have it towed to your nearest repair facility.
It needs to be diagnosed for the cause of this. It may be burning oil that is getting into the combustion chambers or it could be fuel from a possible leaking injector.
If it is continued to be driven, it is very possible that catastrophic engine damage can occur.
