Circle Cycle™ Engine



The Circle Cycle™ Engine is a non-reciprocating internal combustion engine. It employs pistons and cylinders for power generation, and produces energy more efficiently and cleaner than other internal combustion engines.

The design consists of counter-rotating two separate wheels on parallel axes, one holding pistons and one holding cylinders, moving in an orbital pattern. The pistons always face their mating cylinders, coming together to form the stroke, providing the compression and combustion for power without reciprocating motion.

The Circle Cycle™ Engine is an internal combustion engine that runs more efficiently and cleaner than current products. It contains pistons and cylinders attached to rotating wheels that engage each other to create compression and combustion for power without reciprocating motion.

In the Circle Cycle™ Engine, both pistons and cylinders are in motion towards each other for the compression stroke and in motion away from each other for the power stroke. The stroke is not limited by the angle of a connecting rod, as is the case with reciprocating engines. There is no exhaust or intake valves, the configuration of the combustion chamber and the location of the spark plug (if needed) can be optimized for the most efficient burn of fuel.

A significant difference between the CC engine and other internal combustion engines is the “stroke”. With a conventional reciprocating internal combustion engine, the piston begins its “compression stroke” from zero at the bottom of the stroke, then increases its speed until halfway up its stroke, then it begins to slow to another lull at top dead center. The following “power stroke” is the same. Acceleration from a stopped position thru half the power stroke and then deceleration to a stop at the end of the power stroke. No matter how fast the engine is spinning, each piston must still move its mass from a stopped condition, to rapid acceleration, then deceleration and stop. This causes wear and tear on the pistons and cylinders at a faster rate than with the those in the Circle Cycle™ Engine.
