In a method for open-loop and closed-loop control of the number and sequence of strokes in the motive process of a reciprocating-piston internal combustion engine, in particular a reciprocating-piston internal combustion engine with direct injection, it being possible, in the case of leaner-than-stoichiometric combustion, for the residual oxygen not yet used for combustion to be used for further working strokes, and a gas exchange occurring only after the residual oxygen in the combustion chamber has been completely burned or the air ratio lambda in the combustion chamber has fallen below a lower limiting value lambdagrenz.
