quasiturbine rotary air engine seminar powerpoint presentation

The Quasiturbine or Qurbine engine is a proposed pistonless rotary engine using a rhomboidal rotor whose sides are hinged at the vertices. The volume enclosed between the sides of the rotor and the rotor casing provide compression and expansion in a fashion similar to the more familiar Wankel engine, but the hinging at the edges allows the volume ratio to increase. Unlike vane pumps, in which vane extension is generally important and against which the pressure acts to generate the rotation, the Quasiturbine contour seals have a minimal extension and the rotation does not result from pressure against these seals.

Patents for the Quasiturbine (in the most general AC concept with carriages) [1][2] [clarification needed] are held by the family of Gilles Saint-Hilaire of Québec. As well as an internal combustion engine, the Quasiturbine has been proposed as a possible pump design, and a possible Stirling engine.[3] It has been demonstrated as a pneumatic engine using stored compressed air, and as a steam engine.[4]

There are at least four proposed designs:

Two-port with carriages, suitable for use as an internal combustion engine.
Four-port without carriages, suitable for use as a pneumatic or hydraulic engine, steam engine or pump.
Two-port without carriages, a conceptual design which is hoped to combine some of the advantages of the existing two- and four-port prototypes.
Another conceptual design using a fixed charge of gas, with no ports and without carriages, as a Stirling engine. (But not yet referring Malone engine in spite of similar function to Stirling engine)
