Patent ID: 6962137

Claim:
A method of producing a two-cycle, internal combustion, rotary engine comprising the steps of: providing a cylindrical engine wall and end caps wherein an expansion chamber is enclosed; providing a power output shaft with two, single vane, interdigitated, alternating hub section, impellers, rotatable within said expansion chamber whereby said expansion chamber is variably partitioned into an expansion sector and an exhaust sector; providing an expansion confinement cycle, and an exhaust cycle; providing, joined, interdigitated, alternating hub section, single vane impellers whereby dependent rotation is achieved at a hinge like rotation joint; providing expandable seals, with spring tension, and fayed, between the impeller vane mating edges and the interior engine wall whereby relatively gas tight seals are maintained between said impeller and said engine wall; providing a rotation transfer means whereby the impeller rotation, due to the expanding volume within said expansion sector is transferred to the power output shaft; providing at least one fuel injection means whereby fuel is injected into the expansion sector; providing at least one oxidizer injection means whereby oxidizer is injected into the expansion sector; providing an ignition means whereby fuel and oxidizer are ignited in the expansion chamber including a spontaneous combustion means; providing a rotary engine, computer control unit as a control means whereby said engine functions, and said impeller functions, are controlled, and sequenced as needed and; providing an exhaust means, including an exhaust slot, whereby ignition, gaseous, products are controlled, and directed, from the exhaust sector.
