QUASI TURBINE ENGINE

Quasi turbine is a zero vibration continuous combustion rotary engine having four faces articulated rotor with a free and accessible centre rotating without vibration nor dead time and producing a strong torque at low rpm under a variety of modes and fuels. The quasi turbine is also an optimization theory for extremely compact efficient engine concept  It is a new engine concept from Canada offers a design similar to that of rotary engines but with the advantages of a gas turbine-all within the confines of a chamber based on the shape of a Saint Hilaire skating rink profile. Each Quasi turbine device is at the cross road of three modern engines: inspired by the turbines: it perfects the piston, and improves on the Wankel. The Quasi turbine results from a research initiated in 1993 aimed at unifying the compression and power turbine into one entity. This invention is a new hybrid engine concept, midway between the piston and the turbine engine which requires relatively few components such as stator with covers, rotating blades, rocking carriages, wheels, and joints. Quasi turbine is also an environmental friendly engine, which provides an engine concept free from atmospheric gas pollution, noise pollution, thermal pollution etc. In this engine efficiency stays constant and optimum no matter the power of the unit.

Object of this invention is to provide new engine concept unifying the compressor and power turbine into one entity that is a conventional gas turbine engine. Another object of this invention is to provide a low noise, perfectly balanced, zero vibration, low r.p.m engine, giving less time to compression and expansion stroke and allowing more time and volume to the intake combustion stroke.

A further object of this invention is to provide a fast accelerating, zero dead time and to provide an engine almost universal to energy sources, which can run efficiently on pneumatic, steam, hydraulic, liquid and gas fuel internal combustion.

Another object is to provide an engine, which has a short pressure peak, cold intake area characteristics, so that it is suitable for photo detonation mode pure hydrogen fuel combustion. 

Another object is to provide a high weight and volume density engine, without need of any valve, check valve or obstruction and within neither a crankshaft nor a flywheel.
