EGR Valves

EGR (Exhaust Gas Recirculation) Valves

We stock a wide range of EGR Valves

The EGR valve (Exhaust Gas Recirculation) is an anti-pollution device designed as a method of reducing the amount of nitrogen oxide expelled from the vehicle. As the engine heats up the oxygen and nitrogen in the engine's combustion chamber can combine to form nitrogen oxide.  

EGR valves work be recirculating a precise portion of engine fumes back through the engine. These recycled, carbon dioxide rich exhaust fumes cool the engine and displace some of the oxygen that would otherwise be drawn into the engine. Because the engine is cooler and the oxygen levels are lower less nitrogen oxide is produced.
