Abstract
A drive unit and a method for the operation thereof. The drive unit has an internal combustion engine in operative connection with a driven shaft and a reciprocating piston expansion engine in an operative connection with a crankshaft. The driven shaft is mechanically connected to the crankshaft by a clutch in such a way that torque is transmitted from the crankshaft to the driveshaft. The reciprocating piston expansion engine has at least one cylinder, and a fluid is guided from a fluid supply into an interior of the at least one cylinder at least occasionally via an inlet valve and a bypass valve which is arranged in parallel with the inlet valve.
