Title (EN) INTERNAL COMBUSTION ENGINES
(FR) MOTEURS A COMBUSTION INTERNE
Abstract:
(EN) An internal combustion engine includes at least one piston (1) which is reciprocably received in a cylinder (2) which is coupled to a rotary output shaft (17) by a coupling (5, 22) which converts reciprocal movement of the piston into rotary movement of the output shaft. The engine is so arranged that, in use, the fuel/air mixture in the or each cylinder ignites at a predetermined ignition time in the operating cycle of the engine. The coupling is so arranged or programmed that on its compression stroke the speed of the piston decreases abruptly substantially at the ignition time and that the speed of the piston subsequently increases prior to reaching the top dead centre position.
(FR) Moteur à combustion interne comprenant au moins un piston (1) quieffectue un mouvement de va-et-vient dans un cylindre (2), lequel est couplé à un arbre rotatif principal (17) au moyen d'un accouplement (5, 22) qui convertit le mouvement réciproque du piston en mouvement rotatif de l'arbre principal. Le moteur est conçu de manière à ce que lorsqu'il fonctionne, le mélange de carburant et d'air se trouvant dans le cylindre ou dans chaque cylindre s'enflamme à un moment d'inflammation prédéterminé dans le cycle de fonctionnement du moteur. L'accouplement est arrangé ou programmé de telle sorte que pendant la course de compression du piston, sa vitesse décroît très fortement pratiquement à l'allumage, et de sorte que la vitesse du piston augmente ensuite avant d'atteindre la position du point mort supérieur.
