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 acceleration.
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
CONCLUSION The Quasiturbine is a relatively simple technology which could be widely used within a few years with substantial efficiency benefits over piston engines in many applications.
