INTRODUCTION

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. 3

NEED TO INVENTToday 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 about 50 percent is for automobile use.

TECHNICAL FEATURES

Compare to conventional internal combustion engine Green engine is actually six phase engine having higher expansion ratio.

The technical features of green engine are……….Direct Air Intake Direct air intake means that there is no air inlet pipe, throttle

and inlet valves on the air intake system. Air filter is directly connected to the intake port of the engine due to which a high volumetric efficiency obtained, which makes engine to produce a high torque.

Direct fuel Injection Direct fuel injection can provide higher output and torque,

while at the same time it also enhances the response for acceleration.5

TECHNICAL FEATURESSuper Air-Fuel Mixing Since the independent air-fuel mixing phase is having enough

time for mixing air and fuel under strong swirling and hot situation, the engine is capable to burn any liquid or gas fuels without modifications, which in turn reduce the CO emission.

Lowest Surface to Volume RatioThe shape of combustion chamber herein can be designed as global as possible. Thus, a lowest surface is to obtained, and the engine is having less heat losses and high combustion efficiency.

Controllable Combustion time Due to the independent combustion phase, compared to the

conventional engine whose performances lack of efficient combustion time, resulting in heavy CO emission and low fuel usage rate, the Green engine has a sufficient controllable combustion time to match any fuels.6

TECHNICAL FEATURES

High Expansion Ratio High expansion ratio can make the burnt gases to release much

more power. In other words, the waste gases while they run out of the engine are only bringing much less energy with them. Therefore, the engine’s thermal efficiency is greatly raised, and at the same time, the noise and temperature of the exhaust are tremendously dropped.

Vibration Free As major moving parts, vanes which are counted in little mass

and operated symmetrically, the performance of the engine is very smooth. Hence, vibrations are eliminated.

Modular Design Use of modular design is the best way for engine mass

production. Thus stacking of rotors easily extends range of available power.

CONSTRUCTION AND WORKING

The term phase is used instead of stroke is actually associated to the movement of piston and this engine has no 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

8

1.IntakeThe air arrives to the engine through the direct air intake port in the absence of an air inlet pipe, throttle and inlet valves

2.CompressionThe rushing air from the duct is pushed by the blades into the small chambers in the rotor

3.MixingIn this phase the fuel mixes well with the compressed air This is for the deletion of CO emission9

4.CombustionIn this phase chamber rotates towards the end of its pathA spark flies from the plug into the air-fuel mixture

5.PowerThe expanded gas rushes out of the chamber through narrow opening

6.ExhaustAs thermal energy is fully utilized, the exhaust gases bring less heat energy

ADVANTAGES

Small Size and Light Weight The size and weight could be 1/5 or 1/10 of

conventional engine on same output.

Multi-Fuels: any liquid or gas fuels. It is also ideal for coal powder if special anti-

wearing material is applied

High efficiency

Near-Zero Emissions

Smooth Operation12

Fast Accelerating Response

Low Exhaust Temperature

Ideal to Hydrogen Fuel

Highly Reliable

Low cost

13

APPLICATION

The application of green engine in all that instruments and machines where the conventional IC engine are using..

like conventional engine ,it can also be used in automobile and aircraft.

It can also be used in electrical generators to produce electrical energy.

Because of its efficiency and capacity to burn all type of fuel it can be used in submarine and ships also

CONCLUSION

The Green engine prototypes have been recently developed and it has unique design

The limitations have not been determined to any extent

The Green engine is serve the purpose to a large extent

Green engine can work with large variety of fuels which makes it good choice for using nonconventional fuels like biodiesel.

Pollution is minimized by green engine technology.

It’s a new revolutionary engine technology. 20
