Internal combustion rotary toroidal engine comprising a cylinder inside which rotates a toothed wheel with a single tooth with the function of a piston (P). The section of the toroidal cylinder is semicircular. The air and burnt gas exhaust valve (D), the cylinder valve (A), the combustion chamber and on it a burnt gas exhaust valve (E) and a fuel injector or spark plug (F) the cylinder valve (B), the air intake valve (C), are placed outside the toroidal cylinder as they are represented in the drawings 1, 2 and 3. This disposition of these seven parts of the engine is new to the background art and represents the indipendent claim 1. By varying the volume ratio between the toroidal cylinder and the combustion chamber, both ignition type are possible, spontaneus (diesel) and spark ignition. The residual gas between the piston and the valve (B) can flow, if necessary, through two alternative conduits in the combustion chamber Figures 4 and 5 and represent dependent claims 2 and 3. The planned opening of the valves allows the 4 strokes cycle in three rounds. Aim of this invention is the simplification of the engine, eliminating the reciprocating piston, the crankshaft, the connecting rods, the cranks and similar mechanism. |
