Abstract: An engine has a crankshaft. A compression piston within a compression cylinder is connected to the crankshaft such that the compression piston reciprocates through an intake stroke and a compression stroke. An expansion piston within an expansion cylinder is connected to the crankshaft such that the expansion piston reciprocates through an expansion stroke and an exhaust stroke. A crossover passage interconnects the compression and expansion cylinders. The crossover passage includes a crossover compression valve and a crossover expansion valve. A runner section is in a downstream portion of the crossover passage, and a helical end section is integrally connected to the runner section. The helical end section has a funnel spiraling about a valve stem of the crossover expansion valve. The funnel forces incoming air to rotate about the valve stem prior to entering the expansion cylinder to promote turbulent kinetic energy in the cylinder air/fuel charge.

Abstract: PURPOSE:To prevent an exhaust valve from seizing and sticking, by using an air spring as a valve spring so that the exhaust valve is rotated by compressed air which is discharged from an air chamber upon opening of the valve. CONSTITUTION:A piston 100 having saw tooth-like blades 102 is disposed in the air chamber 15 of an air spring for urging an exhaust valve 12 in the closing direction of the latter, and nozzles 103 are formed in the lateral wall of the air chamber. When an engine piston 3 is pushed upward by a cam 1, the pressure in a piston chamber 9 is raised so that a valve rod 11 is depressed downward. When air in the air chamber 15 is compressed and the blades 102 are moved down to the level of the nozzles 103, the compressed air flows through a passage 101 around the blades 102, and is jetted from the nozzles 103 into an air sump 104. As the reaction of the stream of the compressed air, the blades 102 are exerted with torque which rotates the valve rod 11, resulting in the exhaust valve 12 being rotated little by little, thereby it is possible to prevent the exhaust valve from seizing and sticking.

Abstract: A lash compensator for a valve train component of an internal combustion engine is provided that includes an end-cap arranged within a reverse-spring control valve assembly of an axially moveable piston. The piston has a first reservoir and an inner radial wall configured with a through-aperture. The reverse-spring control valve assembly has a control valve housing, a bias spring, an end-cap, and a closing body. The end-cap is configured with a cupped end; an inner side of the cupped end receives a second lower end of the bias spring, and an outer side of the cupped end engages an upper portion of the closing body. The end-cap minimizes or eliminates the variation in flow resistance caused by a variation in end-coil geometry of the second lower end of the bias spring.

Abstract: A valve assembly includes a valve having a head and a stem. The head is configured to seal against a valve seat. The stem has a distal end. A first piston radially extends from the stem of the valve and is enclosed within a housing. A second piston is fixed to the distal end of the stem and seals against the housing. A first chamber is defined by the first piston, second piston and the housing and receives a compressed gas and maintains a desired gas pressure. A spring device is disposed intermediate the first piston and the housing. During normal operation of the engine, the gas pressure within the first chamber seals the head of the valve against the valve seat with the spring device in a compressed arrangement and wherein during periods of insufficient gas pressure the spring device biases the valve to seal against the valve seat.

Abstract: An internal combustion engine is provided with an exhaust valve which has a tapered plug part, a tube-shaped member which is arranged in a region where the exhaust valve is arranged and which is engaged with the tapered plug part of the exhaust valve at one end part which faces a combustion chamber, and a fluid spring for biasing the tube-shaped member to the side facing the combustion chamber. The tube-shaped member is formed so as to be able to move substantially parallel to the direction of movement of the exhaust valve and the other part abuts against the fluid spring. The fluid spring is formed so as to contract using the change in pressure of the combustion chamber as a drive source when the pressure of the combustion chamber reaches a predetermined control pressure.
