EXHAUST GAS RECIRCULATION SYSTEM

An exhaust gas recirculation system includes a turbo charger having a compressor wheel and a turbine wheel, a high-pressure intake passage provided between the compressor wheel and an intake port of an internal combustion engine, a charge air cooler provided on the high-pressure intake passage to cool intake gas, a high-pressure exhaust passage provided between an exhaust port of the internal combustion engine and the turbine wheel, an EGR passage branched from the high-pressure exhaust passage and connected to the high-pressure intake passage, and an EGR cooler for cooling recirculated exhaust gas flowing through the EGR passage by coolant flowing through a coolant recirculation passage of the internal combustion engine. A downstream end of the EGR passage is connected to the high-pressure intake passage at an upstream of the charge air cooler. According to the exhaust gas recirculation system, intake gas mixed with recirculated exhaust gas can be supplied to the engine at desired temperature, so that fuel consumption of the engine can be improved.
