Advantages of the Invention
The invention differs from most of the previous art internal combustion engine in which the combustion chambers expand radially Unlike the present art, this invention provides expansion of combustion chamber between a blade like Rotor that is directly attached to the shaft and extended outward towards the inner surface of the housing of a cavity, and radially rotating inside the cavity. A combustion chamber is formed between a Rotor attached to a shaft and a blade like Blocker, making temporary transitional motions to form a barrier inside the cavity and form a combustion chamber. The combustion chamber is formed between the Blocker and the Rotor during combustion time, the Blocker remains stable and the Rotor rotates radially forcing the shaft to move with it.
This is a radical difference between the original Wankel rotary engine. The Wankel’s rotation of the Rotor is in an elliptical housing and the center of rotation consists of a set of gears to guide the motion in a elliptical cavity. In the most recent patents of so called rotary engines, a reciprocating piston and cylinder configurations is used for combustion chamber and expansion of ignited gas. The Wankel engine housing for the generation of pressured air and combustion of pressured air and gas is elliptical. Elliptical housing for the rotor is one of the sources of problems including the frictions between the housing and the rotor. In order for the elliptical motions to take place, the shaft is connected to series of gears for the elliptical rotations. Generation of elliptical rotation through gear system is the cause and a major contributor of friction.

By comparison:
Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the presently described apparatus and method of its use.
- This invention resorts to a circular housing in which the shaft rotates in a center of the circular housing eliminating the requirements of elliptical motions and the necessity of gear system.
- The Rotor is a blade rotating in a spherical or cylindrical housing along the centerline of the housing resulting in minimal deviation in tolerances of the point of contact between the edge of the Rotor and the housing.
- Minimal tolerance variations avoids severe loading (pressure) between the edges of the Rotor and the internal walls of the housing, preventing frictions and wear and tear.
- The centrifugal force of the rotor in Wankle engine, the variation of tolerances acts as a hammering force destroying the tip of the rotor and the housing.
- The Blade shape Rotor and the Blocker provides for greater combustion chambers volumes within the cavity compared to Wankel engine’s triangular shape rotor (for the same size volume of an engine). This increase in volume of the combustion, results in greater torque and rotational output power.
- Far smaller number of moving parts allows the engine to be built economically with advantage of greater efficiency in terms of conversion of gas to heat.
- Far lower frictions for eventual higher miles per gallon of gas.
- Far lower maintenance cost.
- Different option implementation for the type of engine allows:
- The design allows for the air compression to be implemented within the same cavity or external air suction and pump to be implemented in parallel with combustion cavity injecting pressured air before ignition.
- Combinations of air suction and air compression pump provides a rich mixture of oxygen for powerful turbo engine.
- Three different implementation of the Blocker allows for different types of engines with respect to their usages.
- Turbochargers and superchargers are fans that force compressed air into an engine’s said cavities. Fans in this case are always open at the air intake side and thus will not produce a high pressure compressed air. That is why they are huge for race car engines.
- Bigger and more powerful engines will be built by enlarging the volume of the cavity and larger radiuses of the cylindrical shape housing. This will eliminate the need for multi piston and cylinders, reducing the number of moving parts and manufacturing costs.
- In the present piston and said cavity engines, crankshafts occupy a major portion of the engine volumes. They are not gear driven and they operate under heavy load. The crankshafts are the sources of friction and generation of heat for eventual failure. This invention does not require crankshaft. A small timed gear assembly is used to activate the Blocker to let the Rotor to pass for no friction.
- The present engine crankshafts operate under a heavy load. They require constant and heavy cooling and lubrication accessories adding more weight to an engine. Due to far lower frictions and moving parts of this invention, the need for lubrication and cooling are far smaller.
- Due to far less moving parts, friction and heat generations, this invention, allows an air cooling system, that is sufficient for cooling an engine with less moving parts and frictions compared to water cooling, further reducing weight and cost of manufacturing of an engine.
- Crankshaft are build heavy to bear the load for the actual motion of a vehicle. The heaviness adds to the size and weight of an engine. The present invention provides for a blade like Rotor and Blocker in which the size and weight are insignificant compared to a crankshaft.
- This invention provides for a dual cycle compressed air pump eliminating an open end air intake side of present turbocharge engines. The same concept of cavity along with a Rotor and Blocker provides for suction and compression pumps that:
- Most turbocharged engines us an oversized open end fan to force pressure air into the combustion chamber.

During the ignition, the blast forces the Rotor forward while the Blocker is stationary until the ignited fuel is escaped from the exhaust (20). In the remaining time of the complete cycle, the Blocker moves with faster speed behind the Rotor to get stopped again by the stopped pin (19). The Blocker (8) always trails the rotor (7) to get stopped after the stop pin (19) is inserted into the cylinder. The Rotor passes the stop pin (19) while the stop pin is pulled out and then the Blocker is stopped by the stop pin (19) driven by timer gear assemble (60). At the moment of ignition, the combustion chamber is small and is filled with mixture of pressured air and fuel. The ignition forces the rotor forward, rotating the shaft and thus provide rotational power for motion of a vehicle. The fuel injection valve (14) and spark plug (16), each located at proper phase with respect to the rotation of the shaft (5). At the end of the combustion expansion, the exhaust opening (20) lets the exhaust fuels out.
