A Six-Stroke, High-Efficiency Quasiturbine Concept Engine
With Distinct, Thermally-Insulated
Compression and Expansion Components
Abstract:
One of the most difficult challenges in engine technology today is the urgenneed to increase engine thermal efficiency. This paper presents a Quasiturbine thermalmanagement strategy in the development of high-efficiency engines for the 21st century.In the concept engine, high-octane fuels are preferred because higher engine
efficiencies can be attained with these fuels. Higher efficiencies mean less fuelconsumption and lower atmospheric emissions per unit of work produced by the engine.While the concept engine only takes a step closer to the efficiency principles of Beau deRochas (Otto), it is readily feasible and constitutes the most efficient alternative to theideal efficiencies awaiting the development of the Quasiturbine photo-detonation engine,in which compression pressure and rapidity of ignition are maximized.
