ENGINE 87 Components : Assembly EGR Cooler Module with EGR Valve and By Pass Valve Assembly EGR cooler module consists of the EGR cooler EGR valve Bypass valve The EGR cooler assembly is provided with inbuilt electronic EGR and a by-pass valve. The EGR Cooler is a heat exchanger that is used to cool the exhaust gases before they are recirculated to the intake manifold. The hot exhaust gases are routed into the EGR cooler from the exhaust pipes through the EGR valve. In the EGR cooler, the exhaust gases are made to pass through metal tubes that are surrounded by engine coolant. The cooled exhaust gas is more effective to help to reduce the pollutants. The EGR valve is electrically operated by the EMS. There is an EGR Cooler bypass valve, which is controlled through the EMS using an electro-pneumatic valve.
