ENGINE 86 H. Exhaust Gas Recirculation System (EGR) : Exhaust Gas Recirculation System Schematic Layout :  Description : The Exhaust Gas Recirculation (EGR) system (include EGR cooler module with EGR and bypass valve) is designed to reduce the amount of Oxides of Nitrogen (NOx) created by engine. In EGR system a part of exhaust gas from the exhaust manifold is made to mix with the fresh air going into the engine. The EGR quantity is controlled by ECU based on environmental and engine conditions. When the engine is cold, the exhaust gas is directly fed into the intake manifold through the bypass valve. When the engine warms up and the exhaust gas temperature increases the bypass valve closes. This results in the exhaust gas flowing through the EGR cooler to reduce its temperature. Location :
