Lower Emissions...Reduced Fuel Requirements Reduced Lubrication...Increased Engine Power... Reduced Engine Noise and Vibration Alternative Fuel Adaptability

Spherical Rotary Valve Engine is the most advanced in the world. A conventional piston engine ignites the fuel and air mixture in the combustion cycle and evacuates the gas by-products in the exhaust cycle. These cycles occur thousands of times per minute per cylinder.
The spherical rotary valve system is made up of spheres rotating on a shaft sandwiched between a split head. These spheres are either chain or belt driven via the crankshaft, much like an overhead camshaft.

Each sphere rotates against a matching seal between it and the piston, one for intake and one for exhaust. The spheres have cavities and ports machined into them for the induction of fuel and air on the intake stroke, and the evacuation of fired gases on the exhaust stroke. This design performs exactly the same function as poppet valves, but the design eliminates the poppet valves, valve springs, guides, camshaft, pushrods, rocker arms and other smaller parts. The Rotary engine operates with over 100 fewer parts than convention engines.

In addition, the spherical rotary valve combustion engine utilizes a proprietary seal at the intake and exhaust ports of the cylinder to prevent pressure leakage. This two-piece seal contacts the peripheral surface of the rotary valve and utilizes the compression and expansion of the fuel and air mixture to create a gas-tight seal with the valves. The lubrication of the rotary valve assembly is accomplished by bronze shaft bearings
