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. Quasiturbine 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
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.
invention is an assembly of four carriages supporting the pivots of a four element,
variable shape rotor, which is confined within a chamber (internal housing counter
wall-stator) based on the shape of a Saint Hilaire skating rink profile. This
profile offers the rotary components of the engine a bigger, more uniform radial
path, enabling maximum torque to be reached more efficiently than a normal combustion.
Two lateral plane covers close the engine end. The rotor is composed of four pivoting
blades playing a similar role as the piston or turbine blades. Each pivots sit
into one of the four rocking carriages. Each carriage is free to rotate around
the same pivot in such a way as to be continuously and precisely in contact with
housing counter. A central shaft is not needed for the engine to operate. It can
be driven through a set of coupling arms attached to the blades by means of traction
slots and through a set of arm braces, the ends of which are linked to central
shaft. The central shaft unit can be easily removed through the back cover central
hold with out dismantling the engine
