Six-Stroke, High-Efficiency Quasiturbine Concept Engine
With Distinct, Thermally-Insulated
Compression and Expansion Components

George Marchetti and Gilles Saint-Hilaire


Need to increase engine thermal efficiency. This paper presents a Quasiturbine thermal management 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 fuel consumption a ....etc

The superconducting generator using super conductors in field winding is superior to conventional generator in terms of power system stability, generator efficiency, generator dimensions and weight. They have been expected as a key generator technology to realize large capacity more them 1GVA.. Recently for then advantages are pointed out compared to conventional generator like small internal impedance that is effective to make system voltages in deregulated power system. These technical merits have pushed the development of superconducting gen ....etc

A technique for on-line detection of incipient faults in the windings of turbine - generator rotors has been developed based on the twin signal sensing method. To detect the developing shorts in any winding, two identical pulses are applied to both ends f the winding and are reflected back .Any abnormality in the winding results in the applied signals being reflected through nonsymmetrical circuits. The difference between the reflected signals are amplified and used as signature signal for further processing. This paper describes the developmen ....etc

An electrostatic generator is a mechanical device that produces continuous current . The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon. The development of electrostatic machines did not begin in earnest until the 18th Century. Electrostatic generators operate by using manual (or other) power to transform mechanical work into electric energy. Electrostatic generators develop electrostatic charges of opposite sign rendered to divided conducto ....etc

A variable-speed controller, for an existing 225 kW fixed-speed wind power generator, is presented in this paper. A sensorless direct torque control algorithm-based controller is proposed for the squirrel-cage induction generator. Generator torque reference is derived based on sensorless maximum power tracking mode algorithm, up to the base speed of the generator. A three-phase front-end converter is used here to deliver the generated power to the grid with unity-power-factor operation at all wind speeds. This algorithm is based on direct activ ....etc

What is qusiturbine engine
Rotary engine without crankshaft
Oval housing surrounds a four-sided articulated rotor which turns and moves within the housing.
Produces strong torque at low RPM
In one revolution of the rotor, four power strokes are created.
OBJECTIVES OF QUASITURBINE
It is a new engine concept based on conventional gas turbine engine
A further object of this invention is to provide a low noise, perfectly balanced, less vibration, low r.p.m engine, giving less time to complete a stroke
Anot ....etc
