摘要： A two-cycle, two-cylinder (10), (12) opposed piston (14), (16), (18), (20) internal combustion engine having means for continuously adjusting the stroke of the engine and the blocking and unblocking of intake (88), (92), transfer (90) and exhaust (102) ports with respect to each other as the engine is operating. Corresponding pistons of each cylinder are connected to respective ends of pivotally mounted rocker arms (24) or (24'), and (34) so that pistons in one cylinder move oppositely with respect to pistons in the other cylinder, the piston side surfaces alternately blocking and unblocking transfer and exhaust ports. In a particular embodiment, the rocker arms (24') are each fitted with a flat spring (154) or (154') positioned so as to be in contact with the end of the associated piston rod and deflecting to allow the pistons to move apart at an increased speed in advance of the crankshaft. The springs (154) and (154') are secured and limited so as to provide increasing spring moment as the springs are deflected. Two connecting rods (48) and (59) are provided, one of which is attached at one end to each of the rocker arms at a pivot point distal from the rocker arm pivotal mount (26) or (36) and at the other end to a rotatably mounted eccentric (52), one end of which is formed into a shaft (54) containing a power drive gear (56) operatively connected to a drive shaft (60), the eccentric being rotated due to an up and down motion of the connecting rod. Means (47), (50) and (63), (64) are provided for continuously varying the attachment points of the connecting rods to the rocker arms, thereby altering the allowable pivotable movement of the rocker arm and consequently the stoke or maximum spaced-apart distance of the pistons in each cylinder. Also, the shaft portion (54) of one of the eccentrics forms twisted splines on its outer surface, its associated power drive gear being (56) adapted to mesh with the twisted splines so that the gear is rotated as it is longitudinally displaced along the shaft. Means (104), (106) are provided for continuously displacing this gear thereby changing the angular relationship between the two rocker arms, and thus the relative positioning of the pistons contained in each cylinder. This changed position alters the blocking of the exhaust ports with respect to the unblocking of the transfer ports. Remote combustion chamber (128), (129) and a means (136), (138) for ensuring that the volume in which combustion takes place remains substantially constant during the combustion process.

摘要： Moteur a combustion interne a deux temps, deux cylindres (10, 12) a pistons opposes (14, 16, 18, 20) ayant des moyens pour regler en continu la course du moteur et la fermeture et l'ouverture des lumieres d'admission (88, 92) de transfert (90) et d'echappement (102) les unes par rapport aux autres pendant le fonctionnement du moteur. Des pistons correspondants de chaque cylindre sont connectes aux extremites respectives de culbuteurs montes de maniere pivotante (24 ou 24' et 34) de sorte que les pistons dans un cylindre se deplacent de maniere opposee par rapport aux pistons de l'autre cylindre, les surfaces laterales des pistons fermant et ouvrant les lumieres de transfert et d'echappement. Dans un mode particulier de realisation, les culbuteurs (24') sont montes avec un ressort plat (154 ou 154') positionnes de maniere a etre en contact avec l'extremite de la bielle de piston associee et devier pour permettre au piston de se separer a une vitesse accrue en avance par rapport au vilebrequin. Les ressorts (154 et 154') sont fixes et limites pour fournir un moment elastique superieur lorsque les ressorts sont deflechis. Deux bielles de connexion (48 et 59) sont prevues, dont l'une est attachee a une extremite de chacun des culbuteurs en un point de pivot distal du montage pivotant des culbuteurs (26 ou 36) et a l'autre extremite a un eccentrique rotatif (52) dont une extremite a la forme d'un arbre (54) ayant un engrenage de transmission de puissance (56) connecte a un arbre d'entrainement (60), l'excentrique etant mu en rotation grace au mouvement ascendant et descendant de la bielle de connexion. Des moyens (47, 50 et 63, 64) sont prevus pour modifier continuellement les points d'attache des bielles de connexion aux culbuteurs, modifiant ainsi le mouvement pivotant permis du culbuteur et par consequent la distance maximum de separation des pistons dans chaque cylindre. De meme, la portion d'arbre (54) d'un des excentriques forme des cannelures torsadees sur sa surface externe, son engrenage de transmission de
