In an internal combustion engine, first and second rotating members, one for the intake valve and one for the exhaust valve rotate next to the outside of an engine cylinder on opposite sides thereof when driven by a drive gear attached to the end of the engine's crankshaft. Each rotating member may include a ring gear having a valve port or aperture near its perimeter that cyclically aligns with a corresponding valve port formed through the cylinder wall near the top of the cylinder. A method of controlling valve timing comprises the steps of causing the rotating member containing the second valve port to periodically align in synchronism with the first port to control the passage of an air/fuel mixture and exhaust gases through the combustion cycles of the engine.

A cylinder head assembly for a cylinder of a four stroke internal combustion engine, including an intake rotor assembly that includes an intake rotor body, a first intake rotor shell portion, and a second intake rotor shell portion, and is operable to be rotatably received in at least one through bore of a cylinder head member. An exhaust rotor assembly includes an exhaust rotor body, a first exhaust rotor shell portion, and a second exhaust rotor shell portion, and is operable to be rotatably received in the at least one through bore of the cylinder head member. At least one of the first and second intake rotor shell portions or the first and second exhaust rotor shell portions are operable to be urged outwardly towards or against an interior surface of the at least one through bore of the cylinder head member so as to create a seal therebetween.

The distribution cylinder (CDM) is a simplified, efficient and rational concept for insertion, top sealing and gas evacuation, for a new transformation of the internal combustion engine. It enables the extraction of ninety percent of the components from the old standardized system, which is more than a century and a half old, and which, until now, have performed these vital functions with the known limitations described in this study. The CDM lightens the structure and functionality of the engine, allowing manufacturers to save materials, production time, maintenance and fuel. It allows for the creation of powerful, faster and less polluting engines. It recommends that the four-stroke engine be recalibrated, considerably improving its performance. Thus equipped, it would naturally run faster since it would be freed from the mechanical limitations of its more resistant valve cylinder version The adoption of the timing cylinder, combined with the modern techniques developed for powering today's internal combustion engine, lays the foundation for a new generation of competitive yet lighter and more compact engines. Their torque will not only be more available but also more flexible to serve all uses and all engine sizes.

A valve comprising a rotor, the rotor comprising two passageways and two or more sealing faces. The valve allowing for controlling air flow between four directions. The valve can be capable of operating in a number of operation modes depending on a position of the rotor. The valve design can include a valve-housing with three ports in plane with a first plane and one port normal to the first plane. A rotary valve provides a plurality of predetermined flow modes between four ports. The valve comprises an outer layer and a rotatable inner layer. The inner layer allows for a number of different flow configurations between four ports.

A valve train device includes a shaft, wherein a number of actuation contours for actuating at least one actuation means of a valve of a combustion engine is arranged on the shaft so as to rotate therewith. A sensor unit with a number of sensors is provided, and each sensor of the number of sensors has a spatial sensing area for sensing a physical variable. In at least one axial position, at least one actuation contour of the number of actuation contours is arranged at least in part in the spatial sensing area of at least one sensor of the number of sensors.

An engine with a rotating valve assembly is disclosed. The valve assembly including a housing having an internal cavity, an open top, and an open bottom, the open top and open bottom being in fluid communication with the internal cavity; a valve barrel positioned in the internal cavity and adapted for rotation therein, the valve barrel having an annular peripheral surface and an aperture extending transversely therethrough communicating with the peripheral surface on opposite sides; a first seal assembly positioned in the open top and a second seal assembly positioned in the open bottom, the first and second seal assemblies each include a seal having a sealing surface in mating engagement with the peripheral surface and an aperture extending therethrough.

A rotating liner driving mechanism for converting existing engines castings to a rotating liner configuration (RLE) with minor changes to the engine or casting. A pulley is connected to the main accessory belt in the front of the engine and drives a shaft parallel to the crankshaft but external to the engine. Via a 90 degree gearbox, the driving rotation is turned about normal to the crankshaft and block deck face. This shaft drives a driving gear through a gear cover, which then drives one of the liners. Gears in the liner flanges propagate the rotation to all liners. An inline engine needs only one set of pulleys and driving mechanisms, but a V-engine may require two, one for each bank of cylinders. The driving pulley can have mechanisms included so that the gear ratio between crankshaft and rotating liners can be varied during engine operation.
