The present invention refers to a double-acting, single-cylinder, explosion engine whose peculiarity is to be provided with auxiliary components which permit to optimize the inlet stroke because such auxiliary components are arranged in a way that the gases to be burnt are not inlet by the piston. Such gases are inlet by the auxiliary components. In general the present engine (1) comprises a cylinder (2) in which a piston (3) may run. The median axis of the piston (3) is interested by a through-shaft which is fixed and coaxial to the piston itself. The shaft is divided in two half-shafts (4, 5) having the same size and shape by the piston. The half-shafts (4, 5) comprise pistons (14, 15) which may run in inlet chambers (10, 11) and narrowings (12, 13) or holes, openings, leaks or the like through which the inlet gas passes to reach the respective explosion chambers through heads (8, 9). The cylinder (2) is provided with exhausts (21) at its median part. The above described engine (1) is connected with at least a connecting rod (16) and is able to do two active bursts during a turn of 360 DEG of the connecting rod.
