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： An apparatus and method to enhance the overall performance of engines in one or more of the following ways: by increasing the power output; by reducing the level of unwanted atmospheric emissions; and by reducing engine wear. The apparatus is an engine (e.g., 2-stroke or 4-stroke, diesel or gasoline-fueled internal combustion engine) comprising a crankshaft, crankcase, combustion chamber, oil pan, piston, connecting rod, intake port, exhaust port, and scavenging pump assembly having an air cylinder and an air diaphragm. The scavenging pump assembly allows for the control of air and fuel intake port pressure by controllably boosting an intake mixture into the combustion chamber, while minimizing the potential for engine lubricating-oil to combine with the intake air-fuel mixture.

摘要： Un pistón con alojamientos externos se conecta con al menos dos cigüeñales acoplados, transformando el movimiento reciprocante lineal del pistón en movimiento rotatorio de los cigüeñales. Una camisa de cilindro con la cabeza del pistón forma la cámara de combustión. El espacio interior del pistón con su contraparte estática forma una cámara de admisión-respiro adicional. En la contraparte estática, se pueden ubicar válvulas de ingreso y salida. A partir del movimiento reciprocante del pistón, la cámara de admisión-respiro proporcionará gases de admisión a la cámara de combustión empleando una lumbrera de transferencia. Antes de la lumbrera de transferencia, se puede disponer de una válvula de control para regular el volumen de gases de admisión que entran en la cámara de combustión. Los gases de admisión-respiro no utilizados para la combustión pueden mezclarse con los gases de escape de combustión. La longitud de las conexiones en configuración inversa, proporciona un tiempo adicional a la compresión en su máximo ratio; mejorando el tiempo de la etapa de evaporación y combustión.

摘要： In the field of internal combustion piston engine design, problems of maximizing internal engine efficiency and reliability while reducing cost are solved by this invention. It is an internal combustion piston engine in which each opposed pair of cylinders (1) fires simultaneously, providing symmetric cranking force on the crankshaft (13). Each cylinder (1) is a simple solid of rotation with air-cooling fins (10). Cylinder heads (5) are modular. Each module (5) covers two adjacent cylinders (1), and has liquid cooling channels. All cylinders (1) are identical, and all cylinder heads (5) are identical. The cylinders (1) are held inward against the crankcase (16) by the cylinder heads (5). Each cylinder head (5) is held inward against the cylinders (1) by two tension bolts (42) that span to the opposite cylinder head (5). One tension bolt (42) crosses above the crankcase (16), and one below it. Spark timing intervals of 105 and 135 degrees reduce torsional resonance in the crankshaft, eliminating harmonic balancers.

The piston (20) is substantially disc shaped and may comprise a plurality of cooling fins (20c). The lower part of the engine (1) may be used as a compressor to feed fresh air to the exhaust or to supercharge the engine, or as a pneumatic pump for direct fuel injection.

摘要： When considering the main types of commercial engines available on the market, whether two-stroke, four-stroke or rotary-type, it is found that, and this is commonplace, said engines are highly polluting. The main reason for this lies in the difficulty to manufacture worn gas filters which would not induce restriction. However, that difficulty can be overcome by producing an engine which is itself capable of sustaining a high rate of restriction. The technical solutions disclosed by the invention present several embodiments enabling the engine to tolerate a higher level of restriction and consequently a more dense filtering. These various technical embodiments provide for a novel path for fresh gases through the engine. The invention provides a solution, which is not primarily concerned with fresh gas supply but rather with waste gas absorption, followed by their subsequent evacuation constituting the first stroke of said engine. Indeed, the waste gases are evacuated outwards by two successive steps: the gases are evacuated outwards by pumping, and said discharge generates, in turn, a vacuum which sucks in the burnt fresh gases which in turn finally suck in the fresh gases. Said techniques have the further advantage of producing two stroke engines powered with gas only, and consequently cleaner and more efficient.
摘要翻译：在考虑市场上可用的商用发动机的主要类型时，无论是二冲程，四冲程还是旋转式，都发现，这是司空见惯的，所以发动机污染严重。其主要原因在于制造不会引起限制的磨损式气体过滤器的困难。然而，这种困难可以通过产生本身能够维持高限制的发动机来克服。本发明公开的技术方案提出了若干实施例，使得发动机能够容忍更高水平的限制，并因此允许更密集的过滤。这些各种技术实施例提供了通过发动机的新鲜气体的新途径。本发明提供了一种解决方案，其不主要涉及新鲜气体供应，而是与废气吸收相关，随后是其后续排气构成所述发动机的第一冲程。实际上，废气通过两个连续的步骤向外排出：通过泵送将气体向外排出，并且所述排放物又产生吸入燃烧的新鲜气体的真空，其又最终吸入新鲜气体。所述技术具有生产仅由气体驱动的两冲程发动机的进一步优点，因此更清洁和更有效。

A piston (16) can be moved to-and-fro in said cylinder and is connected to a shaft (26; 50, 52) via a transmission mechanism (18, 32; 18, 56). The shaft can be rotationally driven by the piston. The cylinder (6) is provided with a working chamber (32) that is configured above the piston and a fresh charge chamber (34) that is designed between the piston and a partition wall (10) of the cylinder. A flow path (36) leads from the fresh charge chamber (34) to the lower region of the working chamber (32). Said flow path is freed when the piston is situated in the area of the bottom dead centre.

摘要： A cylinder housing and piston assembly for a two stroke internal combustion engine; said cylinder housing divided by a fixed separator plate from a crankcase portion of said engine; said piston moving reciprocatingly within said cylinder housing; said piston dividing said housing into a combustion chamber portion above said piston and a compression chamber portion between said piston and said fixed separator plate; wherein an air or fuel/air mix charge is initially inducted into said compression chamber portion as said piston moves towards top dead centre (TDC); said air or fuel/ air mix charge transferred to said combustion chamber portion as said piston moves towards bottom dead centre (BDC) proximate said fixed separator plate. With pairs of cylinders or multiples thereof the lower piston is no longer ventilated but becomes a working piston inducting and augmenting the transfer charge to the adjacent transfer chamber with crankshaft disposition at 180 degrees. An optional low resistance pivoting reed valve is described which eliminates opening tension which the air pressure has to overcome with the conventional fixed reed.

摘要： An internal combustion engine includes a slide body having a plurality of rigidly mounted pistons on opposite ends of the slide body. The slide body reciprocates and is connected to a flywheel by shaft and bearing which extends through an angled track in the slide body. As the pistons impart linear movement to the slide body, the flywheel and a drive shaft rotate. Both the slide body and the flywheel are mounted on the interior of the engine. Magnets on the flywheel rotate relative to stationary coil conductors to induce a current. The housing includes four panels, which can be easily assembled and disassembled, which form a housing compartment in which the linearly movable slide piston subassembly and the rotating flywheel are positioned.
