Abstract: An opposed piston engine has a driveshaft with at least one combustion cylinder positioned between opposing, curvilinear shaped cams mounted on the driveshaft, where the center axis of the combustion cylinder is parallel with but spaced apart from the driveshaft axis. A piston assembly is disposed in each end of the cylinder, with one piston assembly engaging one cam and the other piston assembly engaging the other cam. Each piston assembly includes a cam follower that can move along a curvilinear shaped cam to reciprocate the piston assembly within the cylinder. The combustion cylinder includes an intake port in fluid communication with an annular intake channel formed in the engine block in which the cylinder is mounted, and an exhaust port in fluid communication with an annular exhaust channel formed in the engine block.

Abstract: It comprises one or more cylinders with pistons therein and mutually opposed power cams connected to respective first and second rotary shafts. The reciprocating pistons act on the power cams to impart a rotating motion to the rotary shafts. An attachment device is provided for connecting the rotary shafts to each other. The attachment device includes a shifting device for changing the relative angular position of the first and second rotary shafts. The result is engine distribution and compression ratio are changed dynamically.

Abstract: A coaxial Beta type Stirling cycle device, having a power piston and a displacer coaxially positioned in series within an enclosing cylinder. The power piston and power piston shaft have an opening wherein the displacer shaft passes through. A compression chamber is formed between the pistons. An expansion chamber is formed between the displacement piston and one end of the cylinder. There is a gas path provided, so that a working gas within the cylinder can pass back and forth between the expansion chamber and the compression chamber as the pistons reciprocate. The power piston and the displacer each has its own linkage to a common cam body, which has a cam groove for the power piston and a cam groove for the displacer. The cam body is a face cam having multiple cam grooves, or a barrel cam having multiple cam grooves. The cam grooves may be shaped to provide infinitely settable stroke, dwell, and phase angle. A plurality of single-cylinder devices can share a single common barrel cam and shaft, thus making a multi-cylinder “cluster” configuration engine. Each cylinder, combined with its pistons and yoke assemblies, is identical and easily replaceable, thus providing improved reliability, maintainability and reduced part count.

Abstract: An internal combustion engine wherein each cylinder has two pistons placed in the opposite direction and attached together by an arm-type connecting rod and wherein a cylinder head has a rotor blade rotating in the middle between the upper cylinder head and the lower cylinder head whereby the upper cylinder head and the lower cylinder head are perforated with an intake port and an exhaust port. The rotor blade is perforated with one port and rotates by a gear which is at the outer edge of the rotor blade. When the piston reaches the power stroke, it generates force to act on the arm-type connecting rod and when the connecting rod arm moves in a linear motion, it transmits the force towards the crankshaft or the transmission shaft which is attached by a guide rail platform.

Abstract: An internal combustion barrel engine includes an engine housing with a first and second end. An elongated power shaft is longitudinally disposed in the engine housing and defines a longitudinal axis. A combustion cylinder and a guide cylinder are spaced apart and disposed on a common cylinder axis that is generally parallel to the central axis. The cylinders each have an inner end and an outer end, with the inner ends being closer to each other. The outer end of the combustion cylinder is closed. An intake system is operable to introduce a mixture of air and/or fuel into the combustion cylinder. A track is supported between the inner ends of the cylinders and has an undulating cam surface. The track is moveable such that the portion of the cam surface most directly between the cylinders undulates toward and away from the inner end of the combustion cylinder. A double-ended piston includes a combustion end disposed in the combustion cylinder so as to define a combustion chamber between the combustion end and the closed end of the combustion cylinder. A guide end is disposed in the guide cylinder. A midportion extends between the combustion end and the guide end and is in mechanical communication with the guide surface of the track. A variable compression ratio device is operable to move the track axially towards and away from the inner end of the combustion cylinder so as to adjust the compression ratio. Combustion occurs only in the combustion cylinder and does not occur in the guide cylinder.
