Abstract: A valve system/method suitable for an internal combustion engine (ICE), compressor pump, vacuum pump, and/or reciprocating mechanical device is disclosed. The system/method is optimized for construction of a four-stroke ICE. The rudimentary system incorporates an intake engine block cover (IEC) and exhaust engine block cover (EEC) that enclose an intake rotary valve disc (IVD) and exhaust rotary valve disc (EVD) that control intake/exhaust flow through a respective intake rotary valve port (IVP) and an exhaust rotary valve port (EVP) into and out of a combustion cylinder that provides power to a piston and crankshaft. An intake multi-staged valve (IMV) and exhaust multi-staged valve (EMV) provide intake and exhaust flow control for the IVD/IVP and EVD/EVP. An enhanced system may include a variety of intake/exhaust port seals (IPS/EPS), forced induction/discharge (FIN), centrifugal advance (CAD), and/or cooling channel spool (ICS/ECS).

Abstract: A linear actuator for driving an actuating element of an internal combustion engine of a motor vehicle has two scanning elements for scanning opposite sides of a guide cam. The guide cam has a protruding rib against which the two scanning elements are pre-tensioned to permit a play-free scan of the guide cam.

Abstract: The disclosure relates to reciprocating piston engines having four cylinders with a circular cross section, cylinder axes which are parallel to one another, and an output shaft. The cylinder axes, as viewed in axial section, lie at the corner points of a rectangle that is a square, with the output shaft, which extends parallel to the cylinder axes, in the center of the square. Each pair of cylinders which lie diagonally opposite one another are arranged in the same direction, as viewed axially, and in opposite directions, as viewed axially, with respect to the other pair of cylinders. The force or moment from each cylinder is transmitted to the output shaft via a dedicated rotating crank and a toothing system.

Abstract: A barrel engine has a longitudinal output shaft defining a longitudinal axis. A plurality of cylinders is disposed about the output shaft and are each generally parallel to the longitudinal axis. A cam plane is defined perpendicular to the longitudinal axis and disposed between the open ends of the cylinders and a second end of the engine housing. A cam plate is disposed in the engine housing and supported for rotation about the longitudinal axis. The cam plate has a central portion and an outwardly extending cam portion. The cam portion has a cam surface that undulates from one side of the cam plane to the other. A flywheel has a plurality of lobes, each lobe being disposed generally in alignment with an area where the cam surface undulates closest to the open end of a cylinder.

Abstract: The horizontally opposed center fired engine improves on the traditional design of the horizontally opposed engines and center fired engines with a better engine geometry. The present invention utilizes four pairs of opposing pistons to compress a larger volume of air-fuel mixture within four different cylinders. The four different cylinders are radially positioned around a center axle in order to achieve a perfectly symmetric engine geometry. The center axle consists of two different shafts spinning in two different directions, which could drastically reduce engine vibrations in the present invention. Engine vibrations are caused by a change in engine speed and result in a loss of energy. Due to the design, the present invention will only experience energy loss in the form of entropy and friction. Thus, the present invention can convert a higher percentage of chemical energy into mechanical energy than any other internal combustion engine.

Abstract: An internal combustion engine, and integrated electrical generator, both enclosed in a single housing. The engine has at least one cylinder and piston which extends radially from an axis of rotation about which a combination cam plate and generator armature assembly rotates to produce electrical energy as it passes a stationary electrical coil secured within the housing. The engine block, including at least one cylinder, remains stationary.

Abstract: A multi-cylinder barrel internal combustion engine includes a valve actuation mechanism having generally L-shaped rockers for actuating valves in the engine. The rockers are arranged in pairs each pivotally coupled to a common rocker support. The pair of rockers actuate respective valves of an adjacent pair of cylinders in the engine.

Abstract: A barrel engine has an elongated power shaft defining a longitudinal axis. A plurality of cylinders surround the longitudinal axis, with each having a closed end and an open end. An intake system introduces a combustible mixture of air and fuel into each of the cylinders. The power shaft has an intake lobe and an exhaust lobe extending therefrom. The intake system includes an intake valve and an exhaust valve for each of the cylinders. A valve actuation mechanism includes an intake rocker arm with one end in mechanical communication with the intake lobe, the other end in mechanical communication with the intake valve, and a mid-portion that is pivotally supported. The mechanism also includes an exhaust rocker arm with one end in mechanical communication with the exhaust lobe, the other end in mechanical communication with the exhaust valve, and a mid-portion that is pivotally supported.

Abstract: A barrel engine has an engine housing with a first and second end. An elongated power shaft is longitudinally disposed in the engine housing and defines the longitudinal axis of the engine. A plurality of cylinders surround the longitudinal axis, with each having a closed end and an open end. Each cylinder has a central axis. The open ends of the cylinders are directed toward the first end of the housing. An intake system introduces a combustible mixture of air and fuel into each of the cylinders. A track is disposed between the first end of the housing and the open ends of the cylinders such that a portion of the track is disposed generally in alignment with the central axis of each of the cylinders. The track has a cam surface that longitudinally undulates with respect to the open ends of the cylinders. A portion of the cam surface is disposed generally in alignment with the central axis of each of the cylinders.
