  Explosion or internal combustion engine combined with a compressed air machine.

 this latter and before it moves the piston, a work is done that reduces the pressure and thus the initial temperature in the engine; the amount of energy expended in this way is taken back and used to actuate the piston, for which purpose the pressure of the exhaust gases can also contribute.



   For this purpose, the explosion or internal combustion engine is combined with a compressed air engine, specifically in such a way that its associated compression chambers are separated from one another by a movable wall and that their pistons, which are firmly connected to one another, simultaneously execute the compression stroke.

   At the time of the explosion or combustion, this acts on the movable partition, pushes it into the interior of the air chamber and thus reduces its volume and increases the pressure of the air inside. As soon as the two connected pistons start to move, the expansion in both cylinders begins at the same time and, due to the known properties of the compressed air, the work absorbed during its further compression is completely returned by the compressed air motor, in which the expansion takes place up to atmospheric pressure.

 However, this can be remedied by directing the exhaust gases into a chamber located under the piston of the air motor so that they act on the lower piston surface during the following stroke of the piston; this achieves the compounding of the machine.



   In the drawing, an embodiment of such a machine in Figs. 1 and 2 is in

    The engine works as follows: At the beginning of the intake period, the pistons 2 and 4 assume the position indicated in FIG. 1, while the movable partition 7 rests on the stop 15. During the compression period, the gas mixture in the chamber 6 is below the partition 7 , the air in the chamber 5 above this partition is compressed.



    The dimensions of these chambers must be such that the air compression is sufficiently large. to leave the partition 7 in place.



   When the gas mixture is ignited, the force developed by the explosion or combustion acts instantly on the movable septum, while the pressure that occurs is increasing and before the piston 2, its crank, moves
