A combustion engine (10) having internal combustion, comprises a number of engine cylinders (21), which are arranged in an annular series around a common middle drive shaft (11). Each cylinder includes a pair of pistons (44, 45) movable towards and away from each other and a common, intermediate working chamber (K) for each pair of pistons. Each piston (44, 45) is equipped with its piston rod (48, 49) with associated support roller (53) which forms a support against its respective "sine" - curve shaped cam guide device (12a, 12b), which controls movements of the piston relative to the associated cylinder. A least the one (44) of the two pistons (44, 45) in each cylinder (21) is regulatably adjustable axially in the cylinder especially for regulating the compression ratio in the common working chamber (K).
Un moteur à combustion interne (10) comprend un certain nombre de cylindres (21), disposés en séries annulaires autour d'un arbre moteur médian commun (11). Chaque cylindre comprend une paire de pistons (44, 45), qui effectuent des mouvements alternatifs l'un par rapport à l'autre, et une chambre de travail intermédiaire commune (K) pour chaque paire de pistons. Chaque piston (44, 45) comprend une bielle (48, 49) associée à un galet support (53), qui constitue un support contre son dispositif de guidage (12a, 12b) de came, de forme sinusoïdale, commandant les déplacements du piston par rapport au cylindre associé. On peut régler axialement au moins un (44) des deux pistons (44, 45) de chaque cylindre (21) à l'intérieur de ce dernier dans un but de régulation, notamment afin de réguler le taux de compression dans la chambre de travail commune (K).
