摘要： Internal combustion engines that use the pumping motion of the engine pistons to supercharge the cylinder with air/charge are disclosed. The pistons may include a skirt with a field of pockets that provide a ringless, non-lubricated, seal equivalent. The piston heads may be domed with one or more depressions to facilitate the movement of air/charge in the cylinder. The engines also may have non-circular, preferably rectangular, cross-section pistons and cylinders. The engines also may use multi-stage poppet valves in lieu of conventional poppet valves, and may include a split crankshaft. The engines also may operate in an inverted orientation in which the piston is closer to the local gravitationally dominant terrestrial body's center of gravity at top dead center position than at bottom dead center position.

摘要： A two-cycle internal combustion engine with rear compression chamber, other than that of a crank case. This present engine has valves that can be screwed on the engine block near top dead center, and is actuated by air pressure. This present two-cycle engine uses an oil sump similar to that of a four-cycle engine, which eliminates the need to premix oil with the fuel. This present engine has a stationary piston which operates within a movable piston to form a rear-compression chamber. The movable piston has ports near its crown to transfer charge to the combustion chamber. The movable piston also has ports near bottom of its skirt to allow the fuel and air mixture to enter the rear compression chamber. This engine has a piston seat which is adapted to connect the movable piston to the connecting rod.

摘要： A method and apparatus for pumping an intake charge into an engine is disclosed herein. The fuel-powered engine utilizes a barrier between an intake manifold and a crankcase of the engine to substantially protect the intake charge from contamination by engine crankcase oil, while using the natural pumping action of a reciprocating engine piston to pump the intake charge into the combustion chamber.

摘要： A reduced volume scavenging system for a two cycle engine embodying a duplex cylinder having an upper cylinder bore and a reduced-diameter lower cylinder bore. The lower bore communicates with a crankcase that houses a crankshaft, connecting rod(s) and engine lubricating oil. A fixed sleeve lines the upper cylinder bore and extends up into the cylinder head. A piston disposed for reciprocating motion within the fixed sleeve has an attached cylindrical, reciprocating sleeve that extends down into the lower cylinder bore and moves with the piston. The reciprocating sleeve has compression rings that seal the lower bore and the crankcase against blowyby gases that might contaminate the oil. The fixed sleeve has an intake opening in registry with an inlet port in the upper cylinder bore for admission of fresh air-fuel mixture. The fixed sleeve also has an exhaust opening diametrically opposite the intake opening and in registry with an exhaust port in the upper cylinder bore, as well as upper and lower pairs of scavenging openings in registry with transfer passageways recessed into the upper cylinder bore, such that each out stroke of the piston forces fresh air-fuel mixture through the passageways and into the combustion chamber to flush out burnt gases. This arrangement permits use of four cycle engine lubricating methods and apparatus in two cycle engines, without unduly adding to their weight and complexity, thereby reducing the emission of air pollutants and increasing engine life.

摘要： A two-cycle engine having an enclosed crankcase assembly and a cylinder assembly. A cylinder wall is sized to sealingly cooperate with the piston as it reciprocates relative thereto. The cylinder assembly is provided with an exhaust port in a first plane and a pair of diametrically opposed recessed transfer ports positioned in a second plane along the cylinder axis. The cylinder assembly is provided with a pair of decompression slots each formed in the cylinder wall in communication with one of the opposed transfer ports and extending towards the combustion chamber end of the cylinder assembly. The decompression slots having a circumferential width W which is substantially constant and a radially measured depth D which varies generally linearly from a maximum depth at the intersection of the decompression slot and the transfer port to a minimum depth at the uppermost end of the decompression slot.

摘要： A two stroke engine of a particular configuration can have its power output increased by running bigger pistons and using ports in the piston skirt through which to conduct compressed air within the skirt through short passages in the cylinder housing that conduct the air from within the skirt to above the piston. As a result a larger piston can be used for the same spacing and opening size in the block to save the need to redesign the block and the crankshaft. A position adjuster for the piston moves it axially without rotation of the piston ports out of alignment with inlet ports in the housing. The piston rod is held in the crosshead using a flat to prevent rotation while an adjuster nut that is turned creates axial movement in the piston rod with a lock nut securing the final piston position.
