    摘要： A sleeve valve with a valve body that at least partially encircles at least one piston that moves in a reciprocating manner can, at least partially define with the at least one piston a combustion chamber of an internal combustion engine. A valve actuation mechanism can move the sleeve valve between an open position and a closed position to control flow through a port of the internal combustion engine. The sealing edge of the sleeve valve can be urged against a valve seat by an urging force generated by the valve actuation mechanism when the sleeve valve is moved to the closed position. At least one of the sleeve valve and the valve seat can include a valve assistance feature that assists the valve actuation mechanism in resisting forces generated by the internal combustion engine in opposition to the urging force. Related articles, systems, and methods are described.

    摘要： A two stroke supercharged internal combustion engine having a intake valve positioned in and part of the cylinder block wall and a exhaust valve in the cylinder head providing a regulated flow of gasses from bottom to top combustion chamber when scavenging and also isolating the piston rings lubricated with oil to minimize the contamination of the combustion chamber, exhaust gas and crankcase oil.

    摘要： The valve system for opposed piston engines essentially comprises a single poppet valve opening into the common combustion chamber between the two opposed pistons of each piston and cylinder pair. The engine for which the mechanism is adapted includes a rotating internal cylinder surrounding each piston pair, with a stationary outer cylinder or case surrounding the rotating cylinder. The valve is pivotally attached at one side or end thereof to the edge of the valve port of the rotating cylinder, and is actuated by an arm or arms having guides (rollers, etc.) at the distal end(s) thereof, which are captured in corresponding cam track(s) or channel(s) formed in the fixed outer cylinder or case of the engine. The cam track has a variable radius, with the valve arm(s) and guide(s) alternately lifting and lowering as the guide(s) travel(s) in the variable radius cam track(s), thereby closing and opening the valve.
