Circle ellipse engine

A Circle-Ellipse Engine (FIG. 1) comprising five unique major components. These are an identical pair of End Plates (FIG. 1, Items 100 and 100A), a plurality of Vanes (FIG. 1, Item 200), the Rotor (FIG. 1, Item 300), The Housing (FIG. 1, Item 400), and the Drive Shaft (FIG. 1, Item 500). The implementation of this simplified geometry approach supersedes all prior implementations that required complex and expensive to machine cam surfaces, and challenges to seal non-round combustion chambers. This implementation is made possible by precisely positioning the Vane in relationship to the inner cam surface of the Housing using a pin track, and deriving the pin track from a complex transcendental equation that precisely integrates the Rotor, Vane, and Housing geometries, assuring exact placement of the Vane tip for all rotation angles. This implementation addresses all five mandatory requirements of an engine, namely:

• (1) Lubrication is addressed by implementing a plurality of high-precision flow restrictors to deliver the exact disbursement of lubrication oil at the needed locations;
• (2) Cooling is addressed by high volume water and oil cooling, which are directed through openings in the Drive Shaft and Housing, assuring thermal stability;
• (3) Sealing is addressed by using an approach similar to the successful sealing implementation of the Wankel Engine as implemented by Mazda Automobile Corporation;
• specifically materials, coatings, and placement of Apex, Side, and Face Seals;
• (4) Mechanicals are addressed through implementation of sealed bearings, high tolerance components with ample lubrication, and the aforementioned pin track;
• and (5) Thermodynamics requirements are addressed through the precise geometry of the combustion chamber assuring proper compression ratio, thermodynamic cooling, thermodynamic stability of components, properly timed fuel injection, and removal of excess lubrication products through a scavenge system.
• The device as claimed in claim 1, further including a Housing (FIG. 1, Item 400) with an inner elliptical cam surface (FIG. 6, Item 455), provisions for external connection of lubrication oil (FIG. 6, Item 425), passageways for air/exhaust and cooling water (FIG. 6, Items 415, 430, 445, and 450), and internal channels for distribution of lubrication oil (FIG. 6, Item 420) and recovery of excess oil (FIG. 6, Item 440) that is returned to the oil sump;
• The device as claimed in claim 1, further including a Rotor (FIG. 1, Item 300) with a radius equal to that of the minor axis of the internal elliptical cam surface of the Housing (FIG. 6, Item 455), and is partitioned into equal and symmetrical segments (FIG. 5, Item 315) interspersed by radial movement Vanes (FIG. 1, Item 200), and forming combustion surfaces (FIG. 5, Item 305). The internal hub of the Rotor (FIG. 5, Item 335) contains a cooling and lubrication oil manifold to address Rotor and Vane friction and mechanical requirements;
