To continuously change the volume of the combustion chamber without changing the phase of the combustion chamber, this device comprises the cylinder head(10) in which the inhaler port(13) and the exhaustion port(14) are arranged, the second piston(20) which moves upward and downward, opposed to the first piston(4) inside the bore(11) of the cylinder head, thus when the first piston is in the top point, the upper face of the first piston and the volume of the combustion chamber, the lower face of the second piston form is able to be changed.
