Introduction

The Saint-Hilaire family first patented the Quasiturbine combustion engine in 1996

Combustion Cycle of QuasiTurbine Without Carriage


(1)Intake, which draws in a mixture of fuel and air
(2)Compression, which squeezes the fuel - air mixture into a smaller volume.
(3)Combustion, which uses a spark from a spark plug to ignite the fuel.
(4)Exhaust, which expels waste gases (the by-products) from the engine


Combustion Cycle of QuasiTurbine Without Carriage


First the volume increases, which allows the fuel-air mixture to expand. Then the volume decreases, which compresses the mixture into a smaller space.
It is also shown that how one combustion stroke is ending right when the next combustion stroke is ready to fire.

Engine Displacement Clerification


It is generally of public evidence that engine power goes up with displacement but it is not true actually for all piston engines, the displacement is the maximum cylinder volume
Let see what happen when comparing a 50cc four strokes piston engine with a 50cc Quasiturbine at the same RPM ?
The 4 strokes piston will intake 50cc every 2 revolutions, while
the Quasiturbine intakes 8 chambers x 50cc = 400cc in two revolutions
The Quasiturbine will intake 8 times more chambers and fuel-mixture, and produce something like 10 times more power
It should be noted that the Wankel intakes only 1 chamber of fuel-mixture per shaft revolution, but 3 per rotor revolution

Advantages And Disadvantages

Advantages


Zero vibration
Higher toque at lower rpm
Fewer moving parts for less wear and tear
Faster acceleration without a flywheel.
Nearly oil-free operation
Less noise


Disadvantages

It still uses petrol as fuel and this produces carbon emissions
The Quasiturbine engine is still in its infancy. It is still in its prototype phase


Conclusion

For the same shaft RPM as a piston 4-stroke engine, the Quasiturbine strokes are twice as fast and 8 times more frequent, for an impressive torque and power gain.
The Quasiturbine without carriage is a relatively simple technology which could be widely used within a few years with substantial efficiency benefits over piston engines in many applications.
