Abstract: A 4-stroke engine incorporating a mono-shaft multi-valve operating system, the multi-valve operating system incorporating a first cam follower assembly that is associated with an intake valve, a second cam follower assembly that is associated with an exhaust valve, and a cam follower channel assembly that is integrated into a crank web of the engine, the cam follower channel assembly including a base circle channel, a cam channel, and a cross-over channel. The cam follower channel assembly is configured to commonly interact with the two cam follower assemblies to operate the intake valve at a first instance, and the exhaust valve at a second instance, with both instances occurring while the crank web completes two rotations. When either of the two cam follower assemblies engages with a cam channel of the cam follower channel assembly, the cam follower channel assembly is configured to provide a camming operation to operate the respective valve. When either of the two cam follower engages a base circle channel of the cam follower channel assembly, the cam follower channel assembly is configured to prevent operation of the respective valve.

Abstract: Disclosed is a valve system that provides a means of controlling the charging and exhausting of the combustion chamber(s) of internal combustion engines. In this system, asymmetrical valve bodies are first lifted a nominal distance from their sealing surfaces, then are rotated by their non-centered stems, which operate in conventional valve guides. Rapid port opening, relatively long duration at the full open position, and rapid port closing are achieved. This dual-action valve motion is provided by a drum type camshaft featuring radial protrusions to lift the valves from their sealing surfaces and circumferential cam grooves, which rotate the valves in palindromic fashion. A multi-level valve layout allows for relatively larger port sizes, as it lets the valves move without interference with one another. A mechanism for actuating the valves by electromechanical means is also disclosed.

Abstract: A valve train for an internal combustion engine that uses motors to open/close intake valves of cylinders. The motors drive the intake valves for each of a plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals. Since the intake valves are driven for each of the plurality of groups of cylinders that perform an explosion stroke at substantially equal crank angle intervals, the explosion stroke is performed regularly even when an operation is conducted with only a particular group of cylinders. This makes it possible to inhibit driveability deterioration.
