Title (EN) INJECTOR
(FR) INJECTEUR
Abstract:
(EN) A liquid coolant injector for injecting a liquid coolant into a cylinder of a split cycle engine, wherein the liquid coolant has been condensed into a liquid phase via a refrigeration process, the injector comprising, a thermally insulating housing, a liquid coolant inlet, a liquid coolant outlet in fluid communication with the liquid coolant inlet via a liquid coolant flow path wherein the liquid coolant flow path extends through the thermally insulating housing, the thermally insulating housing configured to inhibit vaporisation of the liquid coolant within the liquid coolant flow path, a valve closure member, moveable between a first position in which the valve closure member blocks the liquid coolant flow path and a second position in which the liquid coolant may flow from the liquid coolant inlet to the liquid coolant outlet, and, a driver operable to move the valve closure member between the first and second position in response to a control signal.
(FR) L'invention concerne un injecteur de liquide de refroidissement pour injecter un liquide de refroidissement dans un cylindre d'un moteur à cycle divisé, le liquide de refroidissement ayant été condensé en une phase liquide par l'intermédiaire d'un processus de réfrigération, l'injecteur comprenant, un boîtier d'isolation thermique, une entrée de liquide de refroidissement, une sortie de liquide de refroidissement en communication fluidique avec l'entrée de liquide de refroidissement par l'intermédiaire d'un trajet d'écoulement de liquide de refroidissement, le trajet d'écoulement de liquide de refroidissement s'étendant à travers le boîtier d'isolation thermique, le boîtier d'isolation thermique étant conçu pour empêcher la vaporisation du liquide de refroidissement à l'intérieur du trajet d'écoulement de liquide de refroidissement, un élément de fermeture de soupape, mobile entre une première position dans laquelle l'élément de fermeture de soupape bloque le trajet d'écoulement de liquide de refroidissement et une seconde position dans laquelle le liquide de refroidissement peut s'écouler de l'entrée de liquide de refroidissement à la sortie de liquide de refroidissement et, un dispositif d'entraînement actionnable pour déplacer l'élément de fermeture de soupape entre la première et la seconde position en réponse à un signal de commande.
