Air Injection Pump: Description and Operation

AIR Pump Removal:

PURPOSE
This system is used to reduce Carbon Monoxide (CO) and Hydrocarbon (HC) emissions. It also heats up the catalytic converter quickly, on engine start-up, so the conversion of exhaust gases will occur sooner.

A belt driven pump on the front of the engine supplies the air to the system. Intake air passes through a centrifugal filter fan at the front of the pump, where foreign material is separated from the air by centrifugal force.
