Abstract

La présente invention concerne un moteur à combustion interne alternatif dans lequel un axe central du vilebrequin et une ligne imaginaire le long de la direction de déplacement du piston (1) se situent dans un plan, et dans lequel une ligne imaginaire entre un axe central d'un vilebrequin (5) et un axe central d'un maneton (6) est pourvue d'un angle non nul par rapport à la direction de déplacement d'un piston (1) lorsque le piston (1) se situe dans une position supérieure. L'axe central du maneton (6) peut croiser la bielle (3) à une distance prédéfinie d'un axe de symétrie de la bielle. En variante, l'axe central du maneton (6) peut croiser le bras de manivelle (2) à une distance d'un axe de symétrie du bras de manivelle (2).
