Abstract: An engine has a rotatable crankshaft. A compression piston is received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke during a single rotation of the crankshaft. An expansion piston is received within an expansion cylinder and operatively connected to the crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke during a single rotation of the crankshaft. A crossover passage interconnects the compression and expansion cylinders. The crossover passage includes a crossover compression valve and a crossover expansion valve defining a pressure chamber therebetween. A fuel injector is disposed in the pressure chamber of the crossover passage. Fuel injection from the fuel injector into the crossover passage is timed to occur entirely during the compression stroke of the compression piston.

Abstract: An exhaust valve arrangement includes a cylinder having a top end, an exhaust conduit connected to the cylinder by an opening in the top end of the cylinder, the opening comprising a valve seat, a valve member comprising a valve stem and a valve head on the valve stem, the valve member being movable between a closed position in which the valve head is received in the valve seat and an open position in which the valve head is spaced from the valve seat, and a resilient member arranged to urge the valve member to a closed position. A piston is mounted relative to the valve stem, the piston being disposed in a second cylinder in flow communication with the exhaust conduit and arranged such that a change in pressure in the exhaust conduit changes a degree of compression of the resilient member.

Abstract: The present invention relates to an exhaust valve assembly (18) for a large two-stroke diesel engine (1). The assembly (18) includes an exhaust valve (11) that is movable in opposite directions between a closed position and a open position. A double acting spring assembly (40) is operably connected to the exhaust valve (11) and forms a mass-spring system together with the exhaust valve (11) and the mass of any other parts moving in unison with the exhaust valve (11). The double acting spring assembly (40) stores energy during translation of the exhaust valve (11) back and forth between the closed and open position for subsequent propulsion of the exhaust valve (11) in an opposite direction. Hydraulic means (50) hold the exhaust valve (11) on command from a controller (27) in the closed or in the open position.
