Is a Toroidal Engine a More Powerful Alternative to Reciprocating Engines?

[Kenneth Mann]

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.
