摘要： The double action piston assembly is for an internal combustion engine and has a combustion chamber that has a double action piston connected to one end of a central power rod disposed within the combustion chamber. A first intake air port and a first exhaust port are located in the up side of the combustion chamber. A compression chamber is connected to the combustion chamber. A central power rod passes through the combustion chamber into the compression chamber and out the compression chamber. A fuel mixture is fed into the combustion chamber and ignition means adjacent to combustion chamber to ignite the fuel mixture. At the end of each stroke, the compression exhaust valves are opened and the intake ports and the exhaust ports are open to permit air from the compression chamber to pass through the conduits into the combustion chamber for full scavenging of the combustion chamber.

摘要： An engine is disclosed having cylinders slidably disposed in an engine block. The cylinders reciprocate, engaging movable pistons at each end. A piston and cylinder end define a combustion chamber. A centrally located crankshaft extracts work, and converts the reciprocating motion into rotary motion. Precompression plates fixed to the cylinder reciprocate in precompression chambers to pre-compress and inject an air/fuel mixture. An exhaust gas recovery system, including a catalytic converter in the precompression chamber, extracts work from energy in the exhaust gas stream to improve the engine efficiency. In one embodiment, a central piston assembly is slidable within the cylinder, and reciprocates relative to the cylinder, substantially in synchrony with the motion of the cylinder, thereby producing an effective stroke length that is greater than the stroke length of the cylinder alone. Offset piston journals engage a gliding block to couple the central piston assembly to the crankshaft.
摘要翻译：公开了一种具有可滑动地设置在发动机缸体中的气缸的发动机。气缸往复运动，在每端接合可动活塞。活塞和气缸端限定燃烧室。中心位置的曲轴提取工作，并将往复运动转换为旋转运动。固定在气缸上的预压板在预压室中往复运动，以预先压缩和喷射空气/燃料混合物。包括在预压室中的催化转化器的废气回收系统从废气流中的能量提取工作以提高发动机效率。在一个实施例中，中心活塞组件可在气缸内滑动，并且相对于气缸往复运动，基本上与气缸的运动同步，从而产生大于气缸单独行程长度的有效行程长度。偏移活塞轴颈接合滑动块以将中心活塞组件连接到曲轴。

摘要： Modification to the current two-stroke cycle internal combustion engine, using reduced height piston constructed solidly with piston rods and having rotary valves installed in the transfer and exhaust ports. The piston pre-compresses the fuel-air mix in its lower part without allowing it to enter the crankcase, using auxiliary one-way flow valves operated directly by pressure differentials and transfer parts for the fuel air-mix from the lower part of the piston to the upper part, and a receiving chamber interposed to maintain the pre-compresed fuel-air mixture temporarily.

摘要： A two-cycle internal combustion engine comprises a cylinder with a piston, the cylinder having a port in which an intake valve is placed for feeding a fuel-air mixture from an intake manifold into an intake chamber. The intake chamber is positioned under the position, is isolated from a crank chamber and communicates with a combustion chamber. The combustion chamber is positioned above the piston and communicates with the intake chamber by means of a by-pass manifold, at the inlet of which an intake valve is placed for feeding a fuel-air mixture. An additional piston is provided which is positioned in the cylinder between the crank chamber and the main piston and is rigidly connected to the main piston. A second intake chamber is positioned between the first intake chamber and the additional piston. The second intake chamber isolated from the first intake chamber by means of a partition and communicates with the intake manifold and with the by-pass manifold.

摘要： This invention relates to the field of opposed-piston engines having two pistons in one cylinder configured to have facing heads. Specifically, this is an engine with two crankshafts, two piston heads facing each other in a single cylinder, with the following features: compact size relative to a comparable design, improved or equivalent performance to a comparable design as a result of any of the following: locating crankshafts in a different plane from the cylinder axes; the use of shared duct structures; and the use of an embedded compressor chamber for efficient operation to cover all volumetric requirements, fulfilling the entire thermodynamic cycle, and performing in addition the sweeping and overloading of air or an air/fuel mixture in the cylinder combustion chamber in each revolution of two or more crankshafts, either with or without advancement between the crankshafts.
