Title
(EN) SPLIT-CYCLE AIR-HYBRID ENGINE WITH AIR EXPANDER AND FIRING MODE
(FR) MOTEUR AIR-HYBRIDE À CYCLE DIVISÉ À MODES DE DÉTENTE DE L'AIR ET D'ALLUMAGE
Abstract
(EN) A split-cycle air hybrid engine includes a rotatable crankshaft. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft. An expansion piston is slidably received within an expansion cylinder and operatively connected to the crankshaft. A crossover passage interconnects the compression and expansion cylinders. The crossover passage includes a crossover compression (XovrC) valve and a crossover expansion (XovrE) valve defining a pressure chamber therebetween. An air reservoir is operatively connected to the crossover passage. An air reservoir valve selectively controls air flow into and out of the air reservoir. In an Air Expander and Firing (AEF) mode of the engine, the engine has a residual expansion ratio at XovrE valve closing of 15.7 to 1 or greater, and more preferably in the range of 15.7 to 1 and 40.8 to 1.
(FR) Un moteur air-hybride comprend un vilebrequin rotatif. Un piston de compression est monté coulissant dans un cylindre de compression et est relié fonctionnel au vilebrequin. Un piston de détente est monté dans un cylindre de détente et est relié fonctionnel au vilebrequin. Un passage transversal relie entre eux les cylindres de compression et de détente. Ce passage transversal comprend une soupape transversale de compression (XovrC) et une soupape transversale de détente (XovrE) définissant une chambre de pression. Un réservoir d'air est relié fonctionnel au passage transversal. Une soupape de réservoir d'air commande sélectivement l'écoulement de l'air dans le réservoir d'air et hors de ce dernier. Dans un mode de détente et d'allumage (AEF), le moteur a un taux de détente résiduel à la fermeture de la soupape XovrE de 15,7 à 1 ou plus, et dans l'idéal de 15,7 à 1 et de 40,8 à 1.
