Abstract
A piston internal-combustion engine has a control system for controlling the number of strokes of the combustion process taking place inside a combustion space. As a function of operating parameters, the control system controls the engine operating process such that the process has a variable cycle of at least four strokes. A pushing of a charge out of a combustion space of the piston internal-combustion engine does not take place before one or several operating parameters have reached one defined limit value, respectively.
