Title (EN) Split cycle internal combustion engine
(FR) MOTEUR À COMBUSTION INTERNE À CYCLE DIVISÉ
Abstract:
(EN) SPLIT CYCLE INTERNAL COMBUSTION ENGINE A split cycle internal combustion engine apparatus100 is disclosed herein. The apparatus 00 comprisesa combustion cylinder 20 accommodating a combustion piston22 and a compression cylinder 10 accommodating a compression piston12. The apparatusis arranged to provide compressed fluid to the combustion cylinder20.The compression cylinder 10 iscoupled to a first liquid coolant reservoir 40 and a second liquid coolant reservoir50.Acontroller 60 is arranged to receive an indication of at least one parameter associated with the engine, and control delivery of at least one of the first liquid coolant from the first liquid coolant reservoir 40 and the second liquid coolant from the second liquid coolant reservoir 50 to the compression cylinder 10 based on the indication of the at least one parameter such that the at least one liquid coolant vaporises into a gaseous phase during a compression stroke. [Fig. 1]
(FR) L'invention concerne un appareil de type moteur à combustion interne à cycle divisé (100). L'appareil (100) comprend un cylindre de combustion (20) accueillant un piston de combustion (22) et un cylindre de compression (10) accueillant un piston de compression (12). L'appareil est agencé de façon à fournir un fluide comprimé au cylindre de combustion (20). Le cylindre de compression (10) est couplé à un premier réservoir de liquide de refroidissement (40) et à un second réservoir de liquide de refroidissement (50). Un dispositif de commande (60) est agencé pour recevoir une indication d'au moins un paramètre associé au moteur et commander la distribution d'au moins l'un du premier liquide de refroidissement du premier réservoir de liquide de refroidissement (40) et du second liquide de refroidissement du second réservoir de liquide de refroidissement (50) au cylindre de compression (10) sur la base de l'indication du ou des paramètres de telle sorte que le ou les liquides de refroidissement se vaporisent en une phase gazeuse pendant une course de compression.
