发明名称 TWIN SCROLL TURBOCHARGER DEVICE WITH BYPASS
摘要 A twin scroll turbocharger device for an internal combustion engine comprises a turbine and a compressor, wherein the turbine comprises a first turbine scroll and a second turbine scroll, and wherein at least the first turbine scroll is provided with a turbine scroll inlet valve such that the exhaust gas flow through the first turbine scroll is controllable. The twin scroll turbocharger device is further characterized in that a bypass conduit is provided between a compressor and at least the first turbine scroll. The bypass conduit is provided with a bypass conduit valve such that a flow through the bypass conduit is controllable.

主权项 1. A twin scroll turbocharger device for an internal combustion engine, the twin scroll turbocharger device comprising: a turbine with a turbine wheel configured to be driven by exhaust gas guided from the internal combustion engine, the turbine further comprising a first turbine scroll and a second turbine scroll, wherein the first turbine scroll is provided with a first turbine scroll inlet valve at a first turbine scroll inlet such that the exhaust gas flow through the first turbine scroll inlet of the first turbine scroll is controllable; a compressor with a compressor wheel connected to and configured to be driven by the turbine wheel such that the compressor can pump compressor gas to the internal combustion engine; a turbocharger housing enclosing the turbine and the compressor; and a bypass conduit provided between a pressurized portion of the compressor and a portion of the first turbine scroll provided downstream, in relation to the exhaust gas flow, of the first turbine scroll inlet valve, wherein the bypass conduit is configured to allow fluid communication between the compressor and the first turbine scroll, and wherein the bypass conduit is provided with a bypass conduit valve that is configured to control a flow through the bypass conduit.
