In the case of the internal combustion engine at least one piston acts on a shaft (19), which is designed as a positive control shaft with a circumferential cam. The foot of the piston is designed as a guide rod (18), which is carried in a cover (15) closing the cylinder chamber (14) off from the outside, and is supported by way of a guide roller (20) on the circumferential cam of the shaft. The guide rod (18) is also coupled in at least one disc cam rotating with the shaft, which disc cam has a cam path parallel to the circumferential cam of the shaft, in which cam path carriers (19a) of the guide rod (18) roll over guide rollers (26). <IMAGE>
