Abstract:
1. A compressor housing comprising: a compressor inlet in fluid communication with a compressor volute configured to house a compressor wheel, the compressor inlet configured to provide an air flow to the compressor volute; a compressor outlet in fluid communication with the compressor volute, the compressor outlet being configured to direct a compressed gas to an intake manifold; a compressor exhaust gas recirculation inlet port formed in the compressor housing and in fluid communication with the compressor inlet, the compressor exhaust gas recirculation inlet port configured to combine an exhaust gas flow with the air flow upstream of the compressor wheel, wherein the compressor exhaust gas recirculation inlet port is separate from the compressor inlet; a turbine that includes a turbine wheel rotatably disposed in a turbine housing operationally coupled to the compressor housing; a downstream exhaust gas recirculation supply port formed in the turbine housing and in fluid communication with the exhaust outlet of the turbine housing downstream of the turbine wheel, the downstream exhaust gas recirculation supply port configured to direct an exhaust gas flow through an exhaust gas recirculation conduit to the compressor exhaust gas recirculation inlet port; and an upstream exhaust gas recirculation supply port formed in the turbine housing and in fluid communication with the exhaust inlet of the turbine housing upstream of the turbine wheel, the upstream exhaust gas recirculation supply port configured to direct an exhaust gas flow through the exhaust gas recirculation conduit to the compressor exhaust gas recirculation inlet port.
