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 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.

摘要： A hybrid electric powertrain includes a direct-injection, two-stroke, port scavenged engine in hybrid combination with an electric motor. The engine is configured to use a fuel with wide flammability limits, such as hydrogen, for extremely lean combustion to significantly reduce emissions. The two-stroke engine eliminates the engine displacement problems associated with extremely lean combustion, and the use of a hybrid powertrain allows the engine to be operated efficiently with reduced throttling compared to the prior art. A continuously variable transmission, or a transmission with closely-stepped ratios, is preferably employed.

摘要： A moving cylinder assembly includes a cylinder having a chamber for receiving and engaging a piston, and a housing immediately embracing the cylinder and defining a slot through which the piston is positioned to allow for oscillating movement of the piston within the slot. The cylinder engages in reciprocal oscillating movement with the piston. The immediate embracement of the cylinder by the housing minimizes leakage between the cylinder and the housing. The cylinder assembly is suitable for use in an engine, compressor, pump or vacuum pump.

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 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 yet uses an oil sump similar to that of a four-cycle engine, which eliminating 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： The two-cycle engine comprises a first scavenging opening and second scavenging opening on the inner peripheral wall of a cylinder bore, and a first scavenging passage and second scavenging passage connecting the first scavenging opening and second scavenging opening to the crank chamber. The first and second scavenging passages are provided with an outflow direction change device directing the outflow of an air-fuel mixture flowing out from near the top dead center of the first and second scavenging openings into the cylinder bore and the outflow of the air-fuel mixture flowing out from near the bottom dead center of the first and second scavenging openings into the cylinder bore in different directions.
