A reciprocating piston engine is disclosed having a first inner magnetic field unit, arranged on a first crank web of a crankshaft, and a stationary first outer magnetic field unit, wherein the first inner magnetic field unit and the first outer magnetic field unit together form a first electromagnetic converter, in particular an electric motor or an electric generator. The first crank web has a first compensating weight on a side that is opposite a first connecting rod bearing and that faces radially outwards in relation to a crankshaft axis, wherein the first compensating weight is made of a non-magnetizable material. The first inner magnetic field unit is arranged on a side of the first compensating weight that faces outwards in relation to the crankshaft axis. The invention also relates to a system comprising the reciprocating piston engine, an energy store, an electric control unit and a crankshaft sensor.
