EXHAUST GAS THROTTLE FOR DIVIDED TURBINE HOUSING TURBOCHARGER

摘要

A turbocharger ( 107 ) for an internal combustion engine ( 100 ) includes a turbine having a divided turbine housing ( 109 ). A first inlet port ( 113 ) may be connected to a first volute that is formed in the turbine housing ( 109 ), and a second inlet port ( 114 ) connected to a second volute that is formed in the turbine housing ( 109 ). A center housing may be connected to the turbine housing ( 109 ), and a compressor ( 111 ) may be connected to the center housing. An exhaust gas valve ( 137 ) is in fluid communication with the first inlet port ( 113 ) and arranged to at least partially constrict a flow of exhaust gas from entering the first inlet port ( 113 ) of the turbine ( 109 ), but not constrict the flow of exhaust gas from entering the second inlet port ( 114 ).
