Innovation Solution
A toroidal combustion engine design featuring two piston sets rotating within toroidal cylinders with a single intersection, utilizing a drive train and seal rings for efficient power output, and incorporating a split cycle design where one piston set handles intake and compression while the other handles power and exhaust, with a dual exhaust port configuration for efficient scavenging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If valve mechanisms are used to compartmentalize the torus cylinder in single rotor designs, then combustion chamber compartmentalization is achieved, but device complexity increases and reliability decreases
Solution Approach 1:
The patent removes the valve mechanism entirely from the system. Instead of using valves to control combustion chamber compartmentalization, the invention uses a piston that directly blocks the exhaust port and a separate valve that controls the intake port, eliminating the need for complex valve mechanisms while maintaining combustion control functionality.
Solution Approach 2:
The patent divides the combustion control function into separate components: a piston for blocking the exhaust port and a separate valve for controlling the intake port. This segmentation simplifies the overall system by replacing a single complex valve mechanism with two simpler, more reliable components that perform the same function.
2Device complexity
If ratchet mechanisms, cams, or special gearing are used in dual rotor designs to vary piston motion, then piston compartmentalization is achieved, but device complexity and mechanical speed limitations increase
Solution Approach 1:
The patent employs a dynamic piston design where the piston can rotate freely around the toroidal cylinder while maintaining its blocking function. This dynamic approach eliminates the need for rigid timing mechanisms like ratchets or cams, allowing the piston to adapt its position naturally during the combustion cycle without mechanical constraints that limit speed.
Solution Approach 2:
The piston design allows the combustion chamber to self-regulate the timing of events. The piston blocks the exhaust port during the power stroke and naturally moves to allow exhaust during the exhaust stroke, eliminating the need for external timing mechanisms to control the sequence of operations.
3Power
If multiple torus cylinders intersecting at right angles are used, then power output is increased, but manufacturing precision and control of piston face angles become problematic
Solution Approach 1:
The patent uses a single toroidal cylinder with an asymmetric piston design. The piston has a specific geometry with a leading face and trailing face that are asymmetrically positioned relative to the cylinder axis. This asymmetric design allows the piston to effectively block the exhaust port during the power stroke while maintaining simple manufacturing requirements, avoiding the complexity of coordinating multiple intersecting cylinders with precise face angles.
