Abstract (en)

[origin: WO2009053621A2] The invention relates to an internal combustion engine (1), comprising: a cylinder head (7); a cylinder defined axially by the cylinder head (7); a first piston (3) which is guided with an axial sliding movement in the cylinder and which is secured to a transmission mechanism; a second piston (4) which is guided with an axial sliding movement and which is arranged between the first piston (3) and the cylinder head (7); and means for the controlled introduction of a fluid between the two pistons (3, 4) so as to separate the two pistons by a control chamber (22) having a variable volume.
