System and method for controlling internal combustion engine valve lift and valve opening by an arrangement of cams with overlapping cams track that synchronize and vary the rise, fall, and dwell of the inlet and exhaust valves of an IC engine.

System and method for controlling engine valve lift and valve opening percentage

A multi-speed ratio apparatus to control output for use, but not limited to, either as a module connected to a transmission or as a stand alone transmission. The multi-speed ratio apparatus is connected to a driving member (such as, for example, an engine, motor, or transmission) and a driven member (such as a shaft, differential, or axle). The apparatus having at least one rotary speed converter, the rotary speed converter having a conjugate pair of cam parts and a reaction disk interconnected between the conjugate pair of cam parts. The reaction disk is capable of operably coupling the conjugate pair of cam parts. Further the apparatus includes a grounding member.

Multi-speed ratio apparatus to control shaft output

A thermal compensating desmodromic valve actuation system for opening and closing at least one valve of an engine having a cam assemblage and a driving mechanism for reciprocal movement operably connected to said cam assemblage. The cam assemblage includes a cam mechanism for rotational movement and the driving mechanism also being operably connected to the at least one valve of the engine to move the at least one valve between a valve closed position and a valve open position and between the open position and the closed position in a manner directly related to the rotational movement of the cam mechanism. In addition, mechanisms are provided for adjustably controlling the movement of the at least one valve in order to provide a variable amount of opening of the at least one valve in the open position, and for compensating for the thermal conditions of the engine causes valve stem elongation and contraction. The opening and closing of the at least one valve takes place without the intervention of a spring action.

Desmodromic valve actuation system

A wheel transmission for mobility vehicle includes an input component capable movement at a first rate of motion for selectively driving an output component at either the first rate of motion or a second rate of motion. Operably connected between the input component and the output component is a conversion apparatus which enables the selective drive between the input component and the output component to take place. In addition, the conversion apparatus is capable of preventing the output component from being backdrivable, and thereby acting as a brake, when the vehicle is at rest.
