WHAT IS GREEN ENGINE??? Green engine is the internal combustion engine with

some or major modification in its part 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 with

the contemporary engines and also the exhaust emission are near zero.

The significance of the engine lies in the efficiency when the present world conditions of limited resources of energy are considered.

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 these 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 above 50% is automobile use.

ENERGY CRISIS………

WORLD MARKETED ENERGY CONSUMPTION 1980-2030

TECHINICAL FEATURES• Direct intake • Strong swirling• Sequential variable

compression Ratios.• Direct fuel injection • Super air fuel mixing• Lowest surface to volume

ratios• Constant volume

combustion• Controllable combustion

time

• Multi power pulses• High Working

Temperature• High expansion ratios• Self adapting sealing

system• Vibration free• Modular design• Limited parts and small

size

CONSTRUCTIONIt is a six phases engine.Stroke is related to piston, This engine do not contain piston hence stroke is replaced by phases.It contains two intake ports , two compression chamber, two mixing chamber , two fuel injector ports, two spark plugs and two exhaust as shown in the figure.

Working… 1.INTAKE. Air arrives to engine

through air intake port. A duct is provided on the

side wall of the vanes and rotors.

When air moves through the duct a 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.

WORKING..

3 MIXING The injector spray fuel

into compressed air. The fuel mixes with

compressed air. Proper mixing lead to cut

CO emissions. In mixing phase we

obtain almost ideal air fuel mixture.

4 COMBUSTION As the chamber rotates

at the end of the path before spark plug.

Spark flies from plug to air- fuel mixture.

Denser charge near spark plug enable lean burning of charge.

Working..5 POWER The expanded gas runs

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 gas bring less heat energy.

ADVANTAGES Small size and light

weight. Limited parts. Multi-fuels: any liquids

or gas fuels. Ex: Methanol, Bio-Diesel etc.

High efficiency. Near zero emissions.

ADVANTAGES Smooth operation. Fast acceleration

response. Quietness and low

exhaust temperature. High reliability. Low cost.

• LIKE NORMAL ENGINE

• Low emission.• Low noise.• Low vibration.• Volumetric efficiency high.• Heat lose in exhaust gas is

less.• Fuel feasibility less.• Torque and work output

high.

Conventional engine

• High emission.• High noise.• Low vibration.• Volumetric efficiency low.• Heat lose in exhaust is high.• Fuel feasibility high.• Torque and work output

low.

APPLICATIONS

• Like normal engine green engine can be employed in automobile and aircraft.

• Engineering application.• Military use.• Mines.• Electrical generator.• Ship and submarine.
