Embodiment Construction

[0032] The present invention combines the attributes of a radial rotary engine 10 with an energy storage system. Referring first to FIG. 1, basic operation of a radial rotary engine will be summarized. A plurality of pistons 12, 14, 16 are pivotally connected to a multi-armed connecting rod 18 which in turn encircles a journal 20 of a crankshaft 22. Journal 20 is eccentrically located on crankshaft 22. Crankshaft 22 is located inside annular cylinder block 24. Three axes 26, 28, 30 are seen in the top plan view of FIG. 1. Axis 26 indicates the center line of journal 20. Axis 28 indicates the center line of crankshaft 22. Axis 30 indicates the rotational axis of cylinder block 24. In a radial rotary engine, crankshaft 22 is fixed to its associated vehicle (not shown in its entirety). As will be explained, cylinder block 24 rotates about stationary crankshaft 22. Pistons 12, 14, 16 and connecting rod 18 rotate in tandem with cylinder block, but in respective compound motions. Pistons ...

Abstract

A power plant utilizing a radial rotary engine and incorporating onboard energy storage. The engine is of the type utilized in pre-World War I aircraft, but with certain modifications. The energy storage system exploits the flywheel effect inherent in these engines and optionally also includes auxiliary energy storage in other forms, such as compressed air or electrical. Using a continuously variable transmission enables advantageous use of engine inertia in a coast down mode of driving.

Description

BACKGROUND OF THE INVENTION [0001] This application claims the benefit of U.S. Provisional Patent Application Ser. No. ______ filed on May 13, 2004 as Attorney Docket Number D2GRE001.11.FIELD OF THE INVENTION [0002] The present invention is directed to a power system including a radial internal combustion engine serving as a prime mover, and an associated energy storage system which cooperates with the radial engine. DESCRIPTION OF THE PRIOR ART [0003] Internal combustion engines have long been used to power transport vehicles on land, in and on water, and in the air. Initially, internal combustion engines were directly connected to wheels, propellers, and other elements of a vehicle which acts on an environmental medium to effect propulsion. In some applications, power generated by internal combustion engines has been transformed before bearing on the propulsion effecting elements of the vehicle. For example, diesel electric railway locomotives have diesel engines serving as prime ...
