Purpose

Linear EGR Valve:

The Exhaust Gas Recirculation (EGR) system is used to lower oxide of Nitrogen (NOx) emission levels caused by high combustion temperature. The EGR does this by decreasing the combustion temperatures.

The main element of the system is the linear EGR valve. The EGR valve feeds small amounts of exhaust gas back into the combustion chamber. With the fuel/air mixture diluted by the exhaust gases, combustion temperatures are reduced.
