  • Method for matching the flow capacity of a radial turbine of a turbocharger to a capacity of an internal combustion engine
    Patent number: 5465482
    Abstract: A method for matching the radial turbines of turbochargers, to the respective internal combustion engine, includes managing with a relatively small expenditure of material and labor time and with low costs. In accordance with the method this is achieved by modifying exclusively gas outlet end components of the radial turbine (1). For this purpose, the vanes (5) of the rotor (6) are first shortened and the flow duct (7) between the hub (8) of the rotor (6) and the gas outlet flange (9) is then correspondingly narrowed. This takes place by the insertion of a different, correspondingly enlarged gas outlet flange (9). For this purpose, the gas outlet flange (9) is fastened to the gas inlet casing (2) so that it is easily releasable.
