An air pump, also commonly called a smog pump, is a component used to pressurize fresh air and inject it into the vehicle's exhaust system to help burn hydrocarbon gasses and reduce the emissions that exit the tailpipe. The air pump is typically powered electrically or by a belt. When the air is drawn in, it filters any large dirt particles through a rotating screen and sends the air to the injection points. The air pump uses a check valve to prevent exhaust gasses flowing backward through the air injection system, which can damage the pump or other vehicle components. A failing exhaust air pump may cause the engine to run rough, and you may experience decreased performance and efficiency or increased emissions. A failing smog pump may also activate the Check Engine light, which can be scanned for free at any O'Reilly Auto Parts store help you diagnose and repair the issues you're experiencing. O'Reilly Auto Parts carries replacement smog and air pumps, along with a variety of other exhaust components for most types of vehicles.
