摘要

Reciprocating piston machine, especially an internal combustion engine, comprises at least one cylinder (12) containing a piston (5) for compressing gaseous media, and a drive /driven shaft. One section (4) of a connecting rod (2) is guided by a specially shaped active surface of the piston facing away from the combustion chamber. An Independent claim is also included for a process for operating an internal combustion engine by combusting the fuel/fuel mixture at constant pressure or constant volume in the cylinder. Preferred Features: The main piston is movably attached to a secondary piston (6).
