The exhaust gas recirculation (EGR) system is used to lower oxides of nitrogen (NOx) emission
levels caused by high combustion temperature. It does this by decreasing combustion temperature.
The main element of the system is the EGR valve. The EGR valve feeds small amounts of exhaust
gas back into the combustion chamber. With the fuel/air mixture thus diluted, combustion
temperatures are reduced.
