Abstract: A four-stroke rotary-piston engine has an outer disk, and inner disk, at least one cylinder, at least one piston, at least one piston rod, a fixed gear engaged with a planet gear and a rotary gate valve positioned at a head of the cylinder. The inner disk is rotatable with respect to the outer disk by a compression control device. The planet gear rotates a crank situated on a shaft thereof. The shaft passes upwardly through the inner disk. The crank reciprocates a lever via the piston rod. The lever has an end pivoted on the outer disk so as to push the piston into and out of the cylinder.

Abstract: A continuously variable displacement engine has a plurality of pistons received in a cylinder block and connected to a nutator. A crankshaft with an axis of rotation is carried in a crankcase and incorporates an upper journal with a first angle relative to the axis and a lower journal with a second angle with respect to the axis. A first slider ball is engaged on the upper journal and a second slider ball engaged on the lower journal. A carrier assembly captures the first and second slider balls and incorporates an actuating cylinder. An actuation piston assembly is translatably carried in the actuating cylinder and connected to the crankshaft intermediate the upper journal and lower journal. The actuating piston is controllably translated between a first high eccentricity position and second low eccentricity position. An anti-rotational assembly connects the nutator to a piston case. A balance mechanism is adapted to change the amount of counterbalance for the nutator and the axial location of the counterbalance consistent with eccentricity of the nutator.

Abstract: A compact and efficient Z-twin internal combustion engine is described herein. The Z-twin internal combustion engine comprises horizontally opposed cylinder arrangement that allows for vibration cancellation. The Z-twin engine comprises a central shared cam that drives angled side valves of both the opposing cylinders, thereby greatly reducing moving parts and thus provides a significantly more efficient angled valve approach.

Abstract: A valve with an opening is driven by an electric motor to rotate around the cylinder of an opposed piston engine such that the opening separately matches an intake and exhaust opening on the cylinder to allow fuel to enter the combustion chamber of the engine and allow exhaust to be expelled. The intake and exhaust cylinder openings may be separated from each other by approximately sixty degrees of the outside of the cylinder.

Abstract: An internal combustion engine has a casing and a piston arrangement including a piston coupled to a track. The track is coupled to a shaft and has an inner cam surface and an outer cam surface. The piston is coupled to the track by followers which run on the respective inner and outer cam surfaces of the track to control motion of the piston. A sliding element is connected to the piston and extends below the piston head having a profiled slider surface which engages a corresponding profile in the casing. Also, the casing includes at least two plates having a cutout for receiving the track and a bore for receiving the shaft, and at least two end plates coupled transverse to the plates. At least one cylinder bore is formed in the end plates, and the piston is arranged to move in reciprocating motion in the cylinder bore.

Abstract: The present invention is helical follower internal combustion engine. The present invention has a smooth, cylindrical follower orthogonally attached to a piston rod. The follower fits into two connected half-cylindrical, helical grooves formed by a two-piece cylindrical sleeve. The two-piece cylindrical sleeve is attached to a rotating cylindrical hub. Reciprocal motion of the piston causes rotation of the rotating cylindrical hub. The present invention has a feature that prevents the piston from rotating. The present invention can create electricity by connecting a rotor coil to the rotating cylindrical hub and placing a stator coil in near proximity. In an alternative embodiment, the present invention has an external drive shaft attached to the rotating cylindrical hub.

Abstract: A Polygon Oscillating Piston Engine having multiple pistons on one of two oscillating disks. Each piston moves in a straight line along one of the sides of a polygon within a cylindrical chamber, while the oscillating disks move in an arc about a central shaft. The difference in the straight motion of the piston and angular motion of the oscillating disk is accommodated by a slip sleeve within the piston that slides on a peg or bar mounted to each disk. The engine can be configured to operate as an internal combustion engine that uses diesel fuel, gasoline, or natural gas, or it can be configured as an expander to convert high pressure high temperature gas to rotary power. This engines compact design results in a high power-to-weight ratio.

Abstract: One-stroke internal combustion engines may comprise reciprocating pistons which are either straight or rotary. Three principles are required to make one-stroke engines work: create four dedicated chambers, assign the chambers with coordinated functions, and make pistons move in unison. The functions will be assigned only to a single stroke but an Otto cycle produces a repeating four stroke cycle. Since four functions are performed simultaneously during one stroke, every stroke becomes a power stroke. In reality, 1-stroke engines are physically rearranged 4-stroke engines. Both straight and rotary 1-stroke engines can be modified to comprise opposed piston opposed cylinder (OPOC) engines. The reciprocating piston output of 1-stroke pistons may be converted to continuously rotating output by using crankshafts with split bushings or newly developed Crankgears with conventional bearings. A 1-stroke engine may require only one crankshaft and thus may reduce the number of parts and increase the specific power ratio.
Abstract translation: 一冲程内燃机可以包括直线或旋转的往复活塞。 需要三项原则来使一冲程发动机工作：创建四个专用舱，分配协调功能的室，并使活塞一致移动。 这些功能将只分配给一个笔画，但是奥托循环会产生重复的四冲程循环。 由于在一个行程中同时执行四个功能，所以每个行程变成动力冲程。 实际上，一冲程发动机是物理重新排列的四冲程发动机。 直冲式和旋转式1冲程发动机都可以修改为包括相对的活塞相对气缸（OPOC）发动机。 一冲程活塞的往复活塞输出可以通过使用具有分体衬套的曲轴或新开发的具有常规轴承的曲轴来转换为连续旋转的输出。 一冲程发动机可能仅需要一个曲轴，因此可以减少零件数量并增加比功率比。
