QUASI TURBINE ENGINE
THE NEXT GENERATION ROTARY ENGINES
Department of Mechanical Engineering ,SSET
CURRENT TECHONOLGY AVAILABLE
•4 stroke engines makes positive torques only 17% of time and drags 83% of time
•Many reciprocating parts-problem in balancing forces
•Higher hydrogen emissions-pollution
•The unbalanced inertia force and resulting slap can cause noise and vibrations
•Thermal efficiency is low
QUASI TURBINE -HISTORY
Invented by group of 4 researchers, leaded by Dr. Gilles Saint Hillarie
It was patented in 1996
WHAT IS QUASI TURBINE
The Quasi turbine engine is a proposed piston less rotary engine using a
rhomboidal rotor whose sides are hinged at the vertices. The volume enclosed between
the sides of the rotor and the rotor casing provide compression and expansion in a
fashion similar to the more familiar Wankel engine, but the hinging at the edges allows
the volume ratio to increase . It is a crank less engine and produces high torque at low
Two types of quasi turbine engine models
Quasi Turbine Model Without
An oval housing
Four sided rotor
Inlet and exhaust port
Quasi turbine Model with Carriages
Each carriage consist 2 wheels
Each blade has a filler tip and traction slots
A pivot forms the end of each blade
which draws in a mixture of fuel and air
which squeezes the fuel - air mixture into a smaller volume.
which uses a spark from a spark plug to ignite the fuel.
which expels waste gases (by-products) from the engine.
The coupling arm is fitted to the traction slots
The output shaft is connected to the coupling arm
Simple design and small size
Less vibrations are produced because the engine is perfectly balanced
High thermal efficiency
Better conversion and transmission of mechanical energy
Better torque continuity
Higher torque at lower RPM
Nearly oil free operation
Fewer moving parts so less wear and tear
Compatible with photo detonation
Multi fuel ability
The quasi turbine is built with aluminum and cast iron , Differential thermal expansion or
contraction in material lead to some incidences of leakage
Construction of rotor is bit difficult.
The quasi turbine is still in infancy. It is not used in real world applications .
Aviation industry- High power-to-weight ratio
No vibration -Chainsaws,
Air Compressors, Supercharger
I conclude just by saying that in the near future we would definitely see Quasi turbine used
in more than just your car.
