Title (EN) INTERNAL COMBUSTION ENGINE ARRANGEMENT
(FR) AGENCEMENT DE MOTEUR À COMBUSTION INTERNE
Abstract:
(EN) The present invention relates to an internal combustion engine arrangement (100) for a vehicle (1), said internal combustion engine arrangement (100) comprising a combustion cylinder (106) housing a reciprocating combustion piston, and an expansion cylinder (110) housing a reciprocating expansion piston, said expansion cylinder (110) being arranged in downstream fluid communication with the combustion cylinder (106) for receiving combustion gases exhausted from the combustion cylinder (106), wherein the internal combustion engine arrangement (100) further comprises a pressure tank (112) arranged in fluid communication with the expansion cylinder (110), wherein the internal combustion engine arrangement (100) is further arranged to be operated in a first operating mode in which compressed gas generated in the expansion cylinder (110) is delivered to the pressure tank (112), and a second operating mode in which compressed gas contained in the pressure tank (112) is delivered from the pressure tank (112) to the expansion cylinder (110).
(FR) La présente invention concerne un agencement de moteur à combustion interne (100) pour un véhicule (1), ledit agencement de moteur à combustion interne (100) comprenant un cylindre de combustion (106) qui abrite un piston de combustion à va-et-vient et un cylindre d'expansion (110) qui abrite un piston d'expansion à va-et-vient, ledit cylindre d'expansion (110) étant agencé en communication fluidique en aval avec le cylindre de combustion (106) afin de recevoir des gaz de combustion évacués du cylindre de combustion (106), l'agencement de moteur à combustion interne (100) comprenant en outre un réservoir de pression (112) agencé en communication fluidique avec le cylindre d'expansion (110), l'agencement de moteur à combustion interne (100) étant en outre conçu pour être actionné dans un premier mode de fonctionnement dans lequel un gaz comprimé généré dans le cylindre d'expansion (110) est acheminé vers le réservoir de pression (112) et un second mode de fonctionnement dans lequel du gaz comprimé contenu dans le réservoir de pression (112) est acheminé à partir du réservoir de pression (112) vers le cylindre d'expansion (110).
