INTRODUCTIONThe Quasiturbine or Qurbine engine is a proposed pistonless rotary engine using a rhomboidal rotor whose sides are hinged at the vertices. Invented by group of 4 researchers, leaded by Dr. Gilles Saint-Hilaire

Patented in 1996

ROTARY ENGINES(WANKEL ENGINE)

•Very slow combustions•Has problems in rotor sealing•High emissions-pollution •Less fuel efficiency

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 RPM.

QUASI TURBINE

CONSTRUCTION

• Without carriages

•With carriages

Quasi Turbine Model Without Carriages

•An oval housing•Four sided rotor•Inlet and exhaust port•Spark plug

Quasi turbine Model with Carriages

•4 carriages•Each carriage consist 2 wheels•Each blade has a filler tip and traction slots•A pivot forms the end of each blade

Cycles of internal combustion

• INTAKE, which draws in a mixture of fuel and air

• COMPRESSION, which squeezes the fuel - air mixture into a smaller volume.

• COMBUSTION, which uses a spark from a spark plug to ignite the fuel.

• EXHAUST, which expels waste gases (by-products) from the engine.

QUASI ENGINE WITH CARRIAGES

QUASI ENGINE WITHOUT CARRIAGES

OUTPUT MECHANISIM

•The coupling arm is fitted to the traction slots•The output shaft is connected to the coupling arm

Applications

•Aviation industry- High power-to-weight ratio•No vibration -Chainsaws, • Air Compressors, Supercharger •Military vehicles•Pneumatic engine•Pneumatic pumps

Advantages of Quasi turbine engine

•Simple design and small size•Less noisy•Less vibrations are produced because the engine is perfectly balanced•High thermal efficiency•Better conversion and transmission of mechanical energy•Better torque continuity •Faster acceleration •Higher torque at lower RPM\•Nearly oil free operation•Fewer moving parts so less wear and tear•Compatible with photo detonation•Multi fuel ability

Conclusion

In the future, however, you will likely see the Quasi turbine used in so many application ,like aviation etc
