What is a catalytic converter?

Answer:

Answer

It is a device which causes the oxidization of any remaining hydrocarbons in the exhaust of an internal combustion engine.

In other words, if you engine doesn't burn all of the gasoline, the catalytic converter will burn the rest... up to a point and provided that it doesn't get plugged because your engine is burning oil too.

it is a device on the exhaust pipe that scrubs toxic gas from the exhaust fumes.
