  • the connecting rod neck of the crankshaft of the auxiliary cylinder is 90 ° later than the connecting rod necks of the working cylinders, and the connecting rod necks of the working cylinders are made at the same level, but the working cycle of their cylinders is shifted by one revolution, which allows, in turn, from these working cylinders through the bypass channels, to direct the exhaust gases to the auxiliary cylinder.

Abstract

La présente invention concerne un moteur à combustion interne offrant un meilleur rendement, une puissance supérieure et une réduction du bruit de marche et permettant d’utiliser un compresseur pour augmenter parfois la puissance du moteur sans baisse de rendement. Le moteur se caractérise en ce qu’il comprend entre deux cylindres de combustion interne, avec un cycle type de marche du moteur (admission, compression, combustion du carburant, détente), un cylindre auxiliaire, qui fonctionne avec la pression résiduelle des gaz d’échappement des deux premiers cylindres. Les pistons des cylindres de combustion interne sont montés à un niveau, mais les courses de leur marche sont déphasées sur un tour, ce qui permet de diriger en série des gaz d’échappement vers le cylindre auxiliaire, à chaque tour, via les canaux de dérivation formés dans une culasse. Le maneton du cylindre auxiliaire présente un retard de 90 ° par rapport à ceux des cylindres de combustion interne placés à un niveau. On peut obtenir une légère amélioration du rendement par chauffage de l’air en sortie d’un compresseur au moyen de gaz d’échappement chauds.
