What is qusiturbine engine
Rotary engine without crankshaft
Oval housing surrounds a four-sided articulated rotor which turns and moves within the housing.
Produces strong torque at low RPM
In one revolution of the rotor, four power strokes are created.
OBJECTIVES OF QUASITURBINE
It is a new engine concept based on conventional gas turbine engine
A further object of this invention is to provide a low noise, perfectly balanced, less vibration, low r.p.m engine, giving less time to complete a stroke
Another object of this invention is to provide a fast accelerating, zero dead time
CONSTRUCTION
An oval housing surrounds a four-sided articulated rotor which turns and moves within the housing
The sides of the rotor seal against the sides of the housing, and the corners of the rotor seal against the inner periphery, dividing it into four chambers
Quasiturbine construction cycle
Bluish green ( intake)
Purple(compression)
Red (combustion)
Black (exhaust)
GREEN ( spark plug)
WORKING
IT has four strokes
Intake -> draws in a mixture of fuel and air
Compression-> squeezes the fuel-air mixture into a smaller volume
Combustion-> which uses a spark from a spark plug to ignite the fuel.
Exhaust-> expels waste gases compartment from the engine
As the rotor blades turn, the volume of the chambers varies
First the volume increases, which allows the fuel-air mixture to expand.
Then the volume decreases, which compresses the mixture into a smaller space.
As the mixture is compressed, a spark ignites the mixture which pushes the rotor giving motion.
The exhaust will be given out
ADVANTAGES
The Quasiturbine engine is able to burn fuel more efficiently than any other type of engine.
However unlike a 4-stroke engine, as soon as one combustion stroke is ending the next is ready to fire.
Lesser wear and tear because of less moving parts.
Less vibration
Less pollution
Due to lower RPM gearbox ratio can be reduced
APPLICATION
It can be used as a air compressor
Vehicles
Military applications
Public utilities
MAJOR PROBLEMS
The detonation is still an unsolved problem
It has more moving parts than a wankel engine, a rotary engine
It uses petrol as fuel and this produces carbon emissions
