ABSTRACT:
An Exhaust Gas Recirculation system for an internal combustion engine incorporates a turbocharger having a compressor rotor with two sets of vanes on opposite sides of the rotor disk for compression of charge air and recirculated exhaust gas. The charge air and recirculated exhaust gas streams are segregated in the turbocharger and an inlet and an outlet volute for the recirculated exhaust gas is integral with the turbocharger center housing. A mixer receives the charge air downstream of the charge air cooler and mixes the recirculated exhaust gas for input into the intake manifold. A variable valve intermediate the exhaust manifold of the engine and the inlet of the turbocharger EGR inlet volute controls the amount of recirculation.
