Abstract: PURPOSE: To reduce the material cost and labor for matching by basically changing only the components on the gas outlet side of a radial turbine when matching the radial turbine of a turbocharger to an internal combustion engine. CONSTITUTION: A radial turbine 1 is provided with a gas inlet casing 2 on the gas inlet side, and it is closed by a nozzle ring 3. An impeller 6 with vanes 5 on the drive shaft 4 of a compressor is provided on the gas outlet side. A gas flow duct 7 is constituted of the hub of the impeller 6 and a gas outlet flange 9. The gas outlet flange 9 is fitted to the gas inlet casing 2 by a fastening band 10 and screws 11. Only the components on the gas outlet side of the radial turbine 1 are basically changed for matching the radial turbine 1 to an internal combustion engine, i.e., the vanes 5 are shortened, the gas flow duct 7 is narrowed, and the gas outlet flange 9 is made easily releasable.
