Solution Overview
Problem
Conventional internal combustion engines, including two-stroke and four-stroke types, suffer from inefficiencies in generating kinetic energy due to incomplete combustion, waste gas retention, and high energy wastage, while rotary engines face issues with complexity, airtightness, and low compression ratio, leading to suboptimal kinetic energy production.
Innovation Solution
A rotary internal combustion engine design featuring a circular cylinder seat with first and second explosion chambers, an ignition system, fuel supply, compression, and exhaust/intake means, where a power wheel is slidably coupled to the cylinder, allowing for unidirectional rotation and efficient fuel combustion, ensuring complete waste gas exhaustion and high kinetic energy output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a two-stroke internal combustion engine is used to simplify the structure, then the device complexity is reduced, but the waste gas cannot be exhausted completely and mixes with fresh fuel gas, reducing combustion efficiency and kinetic energy output
Solution Approach 1:
The engine cycle is segmented into distinct phases with separate intake and exhaust ports positioned at different locations. The intake port allows fresh fuel gas to enter while the exhaust port separately expels waste gas, preventing mixing and maintaining combustion efficiency without requiring complex valve mechanisms.
Solution Approach 2:
The piston moves in a circular trajectory within the combustion chamber, creating a spherical or curved motion path. This curved motion, combined with the port positioning, ensures that waste gas is efficiently directed outward through the exhaust port while fresh fuel gas enters through the intake port, achieving complete exhaustion and high combustion efficiency.
2Duration of action of moving object
If the piston moves reciprocally to generate kinetic energy, then the engine can continuously produce motion, but energy is wasted during the upward stroke when fresh fuel gas is exhausted along with waste gas
Solution Approach 1:
The exhaust and intake functions are segmented into separate ports located at different positions. The exhaust port is positioned to expel waste gas during the upward stroke before fresh fuel gas enters through the intake port, preventing energy waste and enabling continuous efficient operation.
Solution Approach 2:
The exhaust port expels waste gas in advance during the upward stroke before the fresh fuel gas enters through the intake port. This preliminary exhaustion action ensures that the combustion chamber is cleared of waste gas before new fuel is introduced, preventing energy loss and maintaining continuous efficient combustion.
3Duration of action of stationary object
If the crankshaft relies on reverse inertia force to rotate during the upward stroke, then the engine can maintain continuous rotation, but the kinetic energy generated is only half of the expected effect due to lack of driving force
Solution Approach 1:
The engine cycle is segmented so that the downward stroke provides the primary driving force through combustion, while the upward stroke is dedicated to exhaust and intake preparation. This segmentation allows the combustion phase to generate maximum power while the other phase prepares for the next cycle, achieving continuous rotation with optimized power output.
Solution Approach 2:
The engine maintains continuous useful action by ensuring that while one stroke is generating power, the other stroke is preparing the combustion chamber for the next power stroke. The separate intake and exhaust ports enable this continuous preparation without interrupting the power-generating downward strokes, maximizing kinetic energy output.
4Temperature
If the piston ascends to compress fuel gas, then combustion can be initiated, but the piston speed is retarded at top and bottom dead centers, reducing overall motion efficiency
Solution Approach 1:
The piston follows a circular trajectory with continuous rotational motion rather than linear reciprocating motion. This curved circular path eliminates the dead center positions where speed would be retarded, maintaining constant motion speed while still achieving the necessary compression and combustion initiation through the rotational compression mechanism.

AI summary
A rotary internal combustion engine includes a cylinder seat and a power wheel. The cylinder seat has a circular cylinder, at least one first explosion chamber disposed on a cylinder wall, and an ignition system, a fuel supply system, a compression assembly, an exhaust and an intake installed thereon for each respective first explosion chamber. The power wheel is slidably coupled to the circular cylinder, and has at least one compression chamber and a second explosion chamber disposed adjacent thereto and when rotated provides connection to the first explosion chamber. As a result of rotation of the power wheel, air and fuel gas are compressed in the compression chamber, collected into the first and second explosion chambers, and then ignited by the ignition system to produce a high explosive yield, so that the power wheel is rotated constantly in a single direction to provide high-efficiency kinetic energy.
