An engine includes a rotatable crankshaft and an expansion piston slidably received within an expansion cylinder and operatively connected to the crankshaft. A crossover passage including walls connects a source of high pressure gas to the expansion cylinder. A crossover expansion (XovrE) valve is operable to control fluid communication between the crossover passage and the expansion cylinder. The XovrE valve includes a valve head and a valve stem extending from the valve head. A fuel injector operable to inject fuel into the crossover passage includes a plurality of spray holes disposed in a nozzle end and aimed at an at least one target at which fuel emitting from the spray holes is directed to form at least one spray pattern. The at least one target is located above a seated position of the XovrE valve head and between the walls of the crossover passage and the XovrE valve stem.

Un moteur comprend un vilebrequin rotatif et un piston d'expansion reçu coulissant dans un cylindre d'expansion et relié fonctionnellement au vilebrequin. Un passage de croisement comprenant des parois relie une source de gaz haute pression au cylindre d'expansion. Une soupape d'expansion de croisement (XovrE) sert à commander une communication fluidique entre le passage de croisement et le cylindre d'expansion. La soupape XovrE comprend une tête de soupape et une tige de soupape s'étendant depuis la tête de soupape. Un injecteur de carburant servant à injecter du carburant dans le passage de croissement comprend une pluralité de trous de pulvérisation disposés dans une extrémité de buse et visant au moins une cible vers laquelle est dirigée l'émission de carburant depuis les trous de pulvérisation pour former au moins un motif de pulvérisation. La ou les cibles se trouvent au-dessus d'une position assise de la tête de soupape XovrE et entre les parois du passage de croisement et de la tige de soupape XovrE.
