<p>The invention concerns a combustion engine, comprising at least one cylinder with in it two oppositely directed reciprocating pistons, which are each connected via a piston rod with a corresponding arm, whereby each arm shows an opening in which a main shaft that connects the two arms is rotatably supported in bearings, which main shaft includes an angle with a centre line of each opening, and means for varying the compression ratio in the cylinder, which compression ratio variation means comprise a division in the main shaft, as well as drive means in order to move the parts formed by it of the main shaft apart from each other. The combustion engine can be provided with at least one spark plug, which protrudes through the bottom of one of the pistons. The combustion engine can also be provided with means for the metering to the cylinder of a supply of air or a fuel / air mixture, which supply means comprise a rotatable metering device along at least one supply opening, connected with the main shaft, which shows at least one metering opening, which can be brought into governing with the supply opening via rotation of the metering device.</p> |
