EXHAUST GAS TURBOSUPERCHARGER FOR AN INTERNAL COMBUSTION ENGINE

摘要

An exhaust gas turbo-supercharger for an internal combustion engine is provided to reduce introduction of heat into a turbine rotor by actively cooling a rotor disk of the turbine rotor. An exhaust gas turbo-supercharger for an internal combustion engine, comprises a turbine for expanding flow of exhaust gas escaped from an engine of the internal combustion engine; and a compressor for compressing flow of combustion air to be supplied to the engine. The turbine includes an inlet housing(10) for supplying flow of exhaust gas to be expanded in the turbine to a turbine rotor. The turbine rotor includes a rotor disk and a plurality of blades. A cooling air line(16) is integrated in the inlet housing so as to guide cooling air to the rotor disk of the turbine rotor.
