Abstract: A split-cycle engine includes a crankshaft rotatable about a crankshaft axis. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through intake and compression strokes during a single rotation of the crankshaft. An expansion piston is slidably received within an expansion cylinder and operatively connected to the crankshaft such that the expansion piston reciprocates through expansion and exhaust strokes during a single rotation of the crankshaft. A crossover passage interconnects the expansion and compression cylinders. The crossover passage includes crossover compression (XovrC) and crossover expansion (XovrE) valves defining a pressure chamber therebetween. At least one of the XovrC and XovrE valves is a balanced valve. A fluid pressure balancer biases the valve for balancing fluid pressures acting against the valve in both opening and closing directions, reducing the forces required in actuating the valve.

Abstract: While ceramic materials possess properties that make them suitable for use in fuel system components, they tend to be susceptible to failure when exposed to tensile stresses. The retention system described herein helps to reduce the tensile stresses experienced by a retained member by providing a retained member with an engagement structure, a multi-piece retention ring that engages the engagement structure, a resilient member coupled to the retention ring, and a retainer coupled around at least a portion of the retention ring and resilient member and spaced apart from the retention ring and/or resilient member by a gap. The retained member, retention ring, resilient member, and retainer are configured so that the retention ring is moveable in an axial direction relative to the retained member and so that the movement of the retention ring acts to expand the resilient member against the bias provided by the resilient member.

Abstract: A compression brake system of an internal combustion engine includes a mechanical system for coupling a camshaft to a brake actuator assembly. The mechanical system includes a stationary housing defining an aperture and a lifter is slidably disposed in the aperture. A resilient element is disposed between the housing and the shoulder and configured to bias the lifter toward the camshaft. The mechanical system is dedicated to compression braking, and therefore the camshaft may have a lobe optimized for braking.

Abstract: A power unit for a small-sized vehicle that includes a valve operating system equipped with a hydraulic valve operation mode change mechanism capable of changing the operational mode of an engine valve, and a clutch device disposed between a crankshaft and a shift mechanism so as to switch hydraulically between connection and disconnection of power transmission, wherein a discharge outlet of one oil pump (209) driven by power transmission from the crankshaft is connected in common to a valve operation mode change mechanisms (63, 64) and a clutch device (102). This enables the hydraulic system to be made compact while avoiding any increase in the overall bulk of the power unit, thus providing a power unit suitable for a small-sized vehicle.

Abstract: A valve drive of an internal combustion engine, which has a reciprocating poppet valve and a spring element which impinges the closed reciprocating poppet valve with force against the action of a valve seat. The force characteristics are substantially independent of the lift characteristics of the reciprocating poppet valve. The spring element is part of a snap-in locking device, which is stationarily mounted in the engine and surrounds the valve stem of the reciprocating poppet valve. The snap-in locking device has snap-in elements arranged in the power flux between the spring element and reciprocating poppet valve. The snap-in elements are supported in the direction of closure of the reciprocating poppet valve on a snap-in surface of the valve stem when the reciprocating poppet valve is closed and on a snap-in surface of the snap-in locking device when the reciprocating poppet valve is open.

Abstract: An intake valve assembly of an internal combustion engine. The intake valve assembly comprises a primary valve, a secondary valve mounted about the primary valve coaxially therewith, a primary valve spring for normally biasing the primary valve toward a closed position, a secondary valve spring for normally biasing the secondary valve toward a closed position, and a secondary valve lifter fixed to the primary valve and axially spaced from the secondary valve when both the primary and secondary valves are in closed positions. The secondary valve is operated mechanically by the secondary valve lifter and fluidly in response to pressure differential between the intake passage and the combustion chamber. The secondary valve is engageable with the primary valve through the secondary valve lifter after opening of the primary valve. The primary and secondary valve springs are normally contracted for continuously biasing the valves toward the closed position thereof.
