EGR- Exhaust Gas Recirculation. The EGR valve operates by injecting exhaust gas into the cylinder reducing cylinder temperature increasing gas mileage. It operates in a very harsh environment where exhaust gas flows through the valve. The carbon and volatile compounds in the exhaust gas build up in the EGR system causing failure.
