TURBOCHARGING ARRANGEMENT AND METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE

摘要

A turbocharging arrangement for an internal combustion engine (1), the arrangement comprising a turbocharger (2) comprising a turbine (2a) and a compressor (2b) being connected to a common shaft (2c) in a rotationally fixed manner, an electric motor (3), and coupling means (4) for coupling the electric motor (2) to the shaft (2c) of the turbocharger (2). The coupling means (4) is arranged to steplessly adjust the torque transmitted between the electric motor (3) and the turbocharger (2). The invention also concerns a method for operating a turbocharged internal combustion engine.
