Experts in Canada have come up with a different kind of engine called the Quasiturbine. It is as revolutionary a paradigm as the Wankel engine and the piston engine, and appears to overcome the limitations of both. The engine will run on any fuel, from petrolium to gas to steam, and can be kick started from anything including compressed air. It requires no oil or lubrication, and will operate just as well submerged or in hostile environments. It requires no timing mechanism and always operates at 100% component use factor.
The Quasiturbine is a concept which improves the conventional engines in 2
ways : in reducing the dead time, and in making better time management in the
engine strokes. With the Quasiturbine, dead time is reduced to an effective
zero. Gas turbines have a compression turbine and a power turbine; the Quasiturbine
results from a research aiming at unifying those two turbines into one entity
(blades of which work alternatively as a compression turbine and a power turbine).
Traditonal rotary engines use the principle of volume variation between a curve
and a moving cord. This new engine concept makes use of a "four degrees of freedom
X, Y, q, ø" rotor, trapped inside an internal housing contour, and does
not require a central shaft or support. This concept is the result of extensive
research for an hybrid turbine-piston engine with a fixed centre of gravity
during rotation (zero vibration).
Concerning environmental issues and energy efficiency, the engine claims to
produces less NOX than a conventunal piston engine and also meets the hydrogen
engine criteria. The engine also boasts other environmental criteria:
