I believe you mean the "EGR" valve. Exhaust Gas Recirculation valve. It is an emissions control device. When the cylinder temperatures exceed 2500 degrees F the EGR valve will open to allow enough exhaust gas (which is inert) to cool the cylinder. This prevents the formation of NOX, which is a huge contributing factor to smog.
An EGR valve takes 5 - 15% of the exhaust the exits your car. You can have troubles with this part due to the carbon build up from all the exhaust passing through it causing the valve to get stuck open or shut.
EGR stands for Exhaust Gas Recirculation. EGR systems cause exhaust gas to be recirculated to the engine cylinders. Recirculating exhaust gas will reduce Nitrous Oxide emissions in diesel and gasoline engines. It does not recirculate exhaust gas in order to burn unburnt fuel. The EGR valve is the control valve which regulates the amount of EGR being recirculated. The valve is controlled form the engine management system.
