Abstract
A turbocharger with an integral Exhaust Gas Recirculation system for an internal combustion engine 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 variable geometry turbine inlet is provided for exhaust backpressure and fuel air mixture control and an integral exhaust gas bypass for recirculating EGR is controlled by an integral valve mounted with the turbine housing.
