Internal combustion engine has turbocharger with turbine wheel on shaft with blades, edge defining number of scallops or notches and scallop fillers between blades

摘要

The engine (10) has a number of combustion cylinders (16) coupled to exhaust and inlet manifolds (20,18) and a turbo charger (14) with a compressor (24) with an inlet for combustion gas, an outlet connected to the inlet manifold and a turbine (22) coupled to the compressor. A shaft rotatably mounted in the turbine housing carries a turbine wheel with a number of blades, an edge defining scallops or notches and scallop fillers between the blades. Independent claims are also included for the following: a turbo charger, a method of operating an internal combustion engine and a turbine
