For BMW Air Pump
An air pump is a device that removes air from an enclosed space or adds air from an enclosed space. When the engine is working, the air pump is driven by the crankshaft transmission belt and then large quantity of air with low pressure enters the diverter valve through the hose. After the fresh air enters the exhaust system, it will accelerate the catalytic reaction of the catalyst and convert carbon monoxide and hydrocarbons in the exhaust gas into carbon dioxide and water in order to reduce the exhaust harmful substances.
