摘要： An engine system includes an internal combustion engine and an air intake assembly configured to supply a flow of air to one or more cylinders of the internal combustion engine. The air intake assembly includes an air supply conduit with a turbine therein, a bypass conduit configured to bypass the turbine, and a fresh air valve configured to selectively direct the flow of air to one or both of the air supply conduit and the bypass conduit. An exhaust conduit is configured to receive a flow of exhaust gas from the internal combustion engine and direct the flow of exhaust gas away from the internal combustion engine. A compressor in the exhaust conduit, which may be coupled to the turbine by a shaft, is configured to rotate and thereby reduce backpressure in the exhaust conduit during idle and partial throttle conditions.
