What does it mean when a car is turbocharged?
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”
Can a bad catalytic converter cause black smoke?
