Abstract
The disclosure relates to a spark-ignited charged internal combustion engine coupled to an exhaust gas turbocharger with a compressor mounted on a rotatable shaft, the rotatable shaft coupled to a turbine and to an electric auxiliary drive. The electric auxiliary drive of the exhaust gas turbocharger may be activated to increase rotational speed of the rotatable shaft to drive the compressor to supply boost to the engine. The electric auxiliary drive may be engaged or disengaged from the rotatable shaft, responsive to engine operating conditions, such as engine speed, rotation speed of the rotatable shaft, exhaust volume, and engine boost demand.
