How does an air pump work for smog?
The air is then used to prolong thorough exhaust burning. This system should consist of a metal duct or hose approximately 1″ in diameter around the air cleaner leading to a metal air check valve, and then the exhaust manifold. Operation: Pump Type – The spinning vanes of the air pump force air into the diverter valve.
