Chevrolet Corvette Secondary Air Injection Pump

The service with the name of Secondary Air Injection Pump in Chevrolet Corvette is a part of the exhaust emission control system known as Air Injection Reactor (AIR) The main function of the pump is to introduce fresh air directly into the exhaust manifold, thus enhancing the extent of the burning of unburned fuel and thus lowering the emission of HC and CO. This system mostly has an electric or belt driven air pump, air control valve, and several check valves and hoses. During engine warm up the air produced by the pump is sent through the exhaust ports to minimize emission rising from a rich air/fuel mixtures. After the engine has warmed up, the system used to deliver air to the intake of the catalytic converter. Also worth mentioning, during deceleration, whereas a trickle of exhaust will kill an engine, a diverter valve safely expels air to the atmosphere. Different generations of the Corvette may have other configurations of the Secondary Air Injection Pump however; the overall operation is somewhat similar in all such car models.

Each OEM Chevrolet Corvette Secondary Air Injection Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
