Abstract
A method for operating a drive apparatus, having a reciprocating-piston engine and an exhaust-gas-driven turbocharger, of a motor vehicle, the reciprocating-piston engine being operated in a four-stroke mode during on-load operation; and the exhaust-gas-driven turbocharger having an electrical machine, in particular a media gap machine, that is operated in generator mode during overrun operation of the reciprocating-piston engine. During overrun operation, the reciprocating-piston engine is operated in a two-stroke mode.
