SUMMARY

The discussion centers on the design of a gearing assembly for a toroidal engine, which aims to achieve a specific output motion in relation to input motion. Participants suggest using a combination of interrupted gears and cams to manage the synchronization of pistons, which must lock in place during non-driven phases. The proposed system is intended to handle significant power while maintaining efficiency, with considerations for mechanical solutions over electronic ones. The conversation highlights the potential advantages and challenges of toroidal engines compared to traditional reciprocating engines.

The main attraction of the toroidal engine is its power density which is a lot greater than that of the conventional reciprocating engine. As example, an engine of the size (to scale) of that illustrated in my previous insertion would have a displacement of approximately 118 cubic inches (1.9 liter). At any given RPM, its equivalent displacement would equal that of a reciprocating engine of twice the displacement (236 cubic in./3.8 l). An increase of toroid "tube" diameter to 4 inches and of the torus center to center of the tube also to 4 inches yields a displacement of approximately 280 cubic inches (4.6 l), (equivalent to 560 cubic inches or 9.2 l). This would be approximately 12 inches in diameter.
