摘要： A two-stage turbocharging system with a high pressure (HP) turbine and a low pressure (LP) turbine, exhaust piping connecting an engine to the HP turbine inlet, exhaust piping connecting the HP turbine outlet to the LP turbine inlet, piping connecting the LP turbine outlet to an aftertreatment device, and branched bypass piping having an inlet and first and second branches, the inlet connected to the engine to HP turbine inlet exhaust piping, the first branch outlet connected to the LP turbine inlet, the second branch outlet connected to the aftertreatment device, and an R2S valve in the first branch and a warm-up valve in said second branch. By opening of the valve, exhaust gas can bypass both the HP and LP turbines and flow to, e.g., the catalytic converter. The R2S valve and the warm-up valve may be integrated into a single exhaust flow control unit.

摘要： To solve the problems of compressor wheel blade flow separation causing surge type noises when a compressor return or recirculation valve is opened or closed, bypass airflow from a compressor recirculation valve is fed into an annular volume, defined between inner and outer walls or shaped as a radially expanded, axially flattened cylindrical space in the compressor inlet, so that the generally unidirectional radial flow from the compressor recirculation valve is re-directed and organized as it is turned from generally radial to generally axial, merging with the general inlet flow and presenting the compressor wheel with airflow of “circumferentially uniform” flow velocity.

摘要： A turbocharger unit having an aerodynamically enhanced pocket, comprising a turbine having a turbine housing and a turbine wheel connected to a shaft along with a compressor having a compressor housing and a compressor wheel mounted on the same shaft. There is an intermediate housing disposed between the turbine housing and the compressor housing, circumscribing the shaft, and having a compressor wheel pocket. There is a series of bearings located in the intermediate housing for supporting the shaft. There is also a series of fluid passages located in the intermediate housing which provide fluid to lubricate the bearings. A seal is used for the prevention of oil from entering the compressor wheel pocket. The compressor wheel pocket has an aerodynamically enhanced pocket for the improvement of pressure balance behind the compressor wheel, preventing the oil in the intermediate housing from entering the compressor housing.
