Abstract
(EN)
An opposed piston engine has a driveshaft with at least one combustion cylinder positioned between opposing, curvilinear shaped cams mounted on the driveshaft, where the center axis of the combustion cylinder is parallel with but spaced apart from the driveshaft axis. A piston assembly is disposed in each end of the cylinder, with one piston assembly engaging one cam and the other piston assembly engaging the other cam. Each piston assembly includes a cam follower that can move along a curvilinear shaped cam to reciprocate the piston assembly within the cylinder. The combustion cylinder includes an intake port in fluid communication with an annular intake channel formed in the engine block in which the cylinder is mounted, and an exhaust port in fluid communication with an annular exhaust channel formed in the engine block.

L'invention concerne un moteur à pistons opposés comprenant un arbre d'entraînement doté d'au moins un cylindre de combustion positionné entre des cames de forme curviligne opposées montées sur l'arbre d'entraînement, l'axe central du cylindre de combustion étant parallèle mais espacé de l'axe de l'arbre d'entraînement. Un ensemble piston est disposé à chaque extrémité du cylindre, un ensemble piston venant en prise avec une came et l'autre ensemble piston venant en prise avec l'autre came. Chaque ensemble piston comprend un galet de came qui peut se déplacer le long d'une came de forme curviligne pour amener l'ensemble piston à effectuer un mouvement de va-et-vient à l'intérieur du cylindre. Le cylindre de combustion comprend un orifice d'admission en communication fluidique avec un canal d'admission annulaire formé dans le bloc-moteur dans lequel le cylindre est monté, et un orifice d'échappement en communication fluidique avec un canal d'échappement annulaire formé dans le bloc-moteur.
