Title
(EN) WORKING-GAS-CIRCULATION-TYPE ENGINE
(FR) MOTEUR DE TYPE À CIRCULATION DE GAZ UTILE
(JA) 作動ガス循環型エンジン
Abstract
(EN) An working-gas-circulation-type engine (1) comprising: a combustion chamber (11) in which a working gas (Ar) having a higher specific heat ratio than air can expand as fuel (H2) combusts; a circulation path (20) capable of circulating gas, which contains the working gas (Ar), from the exhaust side to the intake side of the combustion chamber (11) and again supplying the gas to the combustion chamber (11); and a control device (60) for changing, on the basis of the specific heat ratio of the gas which circulates in the circulation path (20), the control parameter for controlling the combustion of the fuel (H2). The configuration enables the working-gas-circulation-type engine (1) to achieve stable output.
(FR) La présente invention a trait à un moteur de type à circulation de gaz utile (1) qui comprend : une chambre de combustion (11) dans laquelle un gaz utile (Ar), doté d'un coefficient de chaleur spécifique supérieur à celui de l'air, qui peut se dilater en tant que combustible (H2) fait l'objet d'une combustion ; une voie de circulation (20) permettant de faire circuler le gaz, qui contient le gaz utile (Ar), depuis l'évacuation jusqu'à l'admission de la chambre de combustion (11) et d'alimenter de nouveau la chambre de combustion (11) en gaz ; et un dispositif de commande (60) permettant de changer, en fonction du coefficient de chaleur spécifique du gaz qui circule dans la voie de circulation (20), le paramètre de commande afin de contrôler la combustion du combustible (H2). La configuration permet au moteur de type à circulation de gaz utile (1) d'obtenir une sortie stable.
(JA)  燃料(H2)の燃焼に伴って空気より比熱比の高い作動ガス(Ar)が膨張可能である燃焼室(11)と、作動ガス(Ar)を含むガスを燃焼室(11)の排気側から吸気側に循環させ再び燃焼室(11)に供給可能である循環経路(20)と、循環経路(20)を循環するガスの比熱比に基づいて、燃料(H2)の燃焼を制御するための制御パラメータを変える制御装置(60)とを備えることを特徴とするので、安定した出力を得ることができる作動ガス循環型エンジン(1)を提供することができる。
