Rotary engine having two rotors with intersecting pathways

Abstract

An engine including a block that has first and second intersecting pathways, and first and second rotors positioned within the first and second pathways, respectively. The first and second rotors are moveable within the first and second pathways, respectively, between first and second combustion positions. A first combustion chamber is formed within the first pathway between the first and second rotors when they are in the first combustion position, and a second combustion chamber is formed within the second pathway between the first and second rotors when they are in the second combustion position. The pathways and rotors are preferably torus shaped, and the rotors preferably have concave leading and trailing ends. The engine block preferably has a single intake for both of the first and second combustion chambers. Recesses are preferably formed in the block to receive seals that engage the rotors.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]1. Field of the Invention[0004]The present invention relates generally to engines and, more particularly, to an enhanced efficiency engine.[0005]2. Description of Related Art[0006]The majority of conventional internal combustion engines include pistons each of which linearly reciprocates within a cylinder formed in an engine block. These conventional engines are relatively inefficient because the piston must move in a direction that opposes the expansion of a combusted air / fuel mixture within the cylinder in order to exhaust that combusted air / fuel mixture from the cylinder and, as a result, energy from the combustion of the air / fuel mixture is lost. In addition, because the piston is moving in a direction that opposes the expansion of the combusted air / fuel mixture, mechanical energy from the engine must be ...

AI Technical Summary

Benefits of technology

This design significantly improves engine efficiency by reducing energy loss during exhaust and effectively converting heat into electric energy, potentially achieving efficiencies greater than 50%.

Problems solved by technology

These conventional engines are relatively inefficient because the piston must move in a direction that opposes the expansion of a combusted air / fuel mixture within the cylinder in order to exhaust that combusted air / fuel mixture from the cylinder and, as a result, energy from the combustion of the air / fuel mixture is lost.

The engine has a relatively complex structure because two inlets are formed in the engine for each of the pistons.

The engine also does not include seals to effectively prevent the inadvertent exhaust of combusted air and fuel.

The engine in Kamiya also has a relatively complex structure in that an inlet is formed in the engine for each piston.

Further, the ends of each piston have an S-shape, which prevents the engine from effectively sealing against the inadvertent exhaust of combusted air and fuel.

The failure to convert this heat energy into useable mechanical or electric energy is another inefficiency of conventional engines.
