WHAT IS GREEN ENGINE
Green engine is the internal combustion engine with some or major modifications in its parts and design.
The green engine is one of the most interesting discoveries of the new millennium.
The efficiency of this engine is high when compared to the contemporary engines and also the exhaust emissions are near zero.
The significance of the engine lies in the efficiency when the present world conditions of limited resources of energy are considered.
Green engine is a 6 phase engine which has a very low exhaust emission, high efficiency, low vibrations etc….
Its uniqueness to adapt to any fuel which is also well burnt.
NEED TO INVENT
Today world is facing the major problems regarding energy crisis.
Along with this we are facing major environmental trouble due to increase in harmful gases which are evolved from nowhere else but the combustion of conventional energy sources.
Major portion of fuels is burnt in the engines used for various purposes like main automobiles, generators, power plants etc.
Statistics show that, the daily consumption of petroleum all over the world today is 40 million barrels, of which about 50 percent is for automobile use.
TECHNICAL FEATURES
The green engine is an actual 6 phase internal combustion engine: Intake, compression, mixing, combustion, power and exhaust.
Sequential Variable Compression Ratio.
Direct Air Intake
Direct fuel Injection
Super Air-Fuel Mixing
Lowest Surface to Volume Ratio
Controllable Combustion time
High Expansion Ratio
Vibration Free
Modular Design
CONSTRUCTION
The term phase is used instead of stroke which is actually associated to the movement of piston.
The six phases are : Intake , compression, Mixing, Combustion, power and exhaust.
The engine has a set of vanes, a pair of rotors having
a no. of small pot like containers.
The engine also contains two air intake ports, and a pair of fuel injectors and spark plugs.
WORKING
1.Intake
Air arrives to engine through air intake port.
A duct is provided on the side walls of the vanes and rotors.
When air moves through duct strong swirls generates.
Air pushes the vane blade, imparts rotation in the small rotors.
The inlet duct ends with very narrow opening.
2.Compression
The rushing air from the duct is pushed by the blades the small chambers in the rotor
Compression obtained by such procedure is satisfactory
Compressed air in swirling state mixed with fuel
3. Mixing
The injector sprays fuel into compressed air.
The fuel mixes well with compressed air.
Proper mixing leads to cut CO emissions.
In mixing phase we obtain almost ideal air-fuel mixture.
4.Combustion
As the chamber rotates at the end of its path it is positioned before spark plug.
Spark flies from plug into air-fuel mixture.
Denser Charge near spark plug enable lean burning of charge.
5.Power
The expanded gas rushes out of the chamber through narrow opening.
Pushing the vane in the process.
Sudden increase in volume ensure that more power is released.
6.Exhaust
As thermal energy is fully utilized, the exhaust gases bring less heat energy.
ADVANTAGES
Small Size and Light Weight.
Limited parts.
Multi-Fuels: any liquid or gas fuels.
ex: Methanol, Bio-Diesel, etc.
High efficiency
Near-Zero Emissions
Smooth Operation
Fast Accelerating Response
Quietness and Low Exhaust Temperature
Highly Reliable
Low cost
CONCLUSION
Pollution is minimized by green engine.
it’s a new revolutionary engine technology.
It has unique design.
The limitations have not been determined to any extent.
Green engine can work with large variety of fuels which makes it good choice for using non conventional fuels like biodiesel.
The Green engine is serve the purpose to a large extent
