The internal combustion motor, with self ignition during running, brings the combustion gas to atmospheric pressure in the expansion chamber (12) when under a partial load shortly before the end of its expansion phase. The piston (1) is moved in the direct...

The engine includes a separate expansion chamber (3) with a piston (4) driving a drive shaft (32) via a cam transmission, in which the pushing member (30) can be lifted off the cam disk (31). This produces a timing independent of the continuous rotation of...
