Why it is necessary AND WHY IT IS evolved ?

Facing major problems regarding energy crisis, Due to limited fuel resources available around us like petroleum products, coal, natural gas etc.

According to The United Nations Energy statistical survey, consumption of petroleum constitutes approximately 60 percent of energy used from all sources, out of which, the daily consumption of petroleum all over the world today is 40 million barrels, of which about 50 percent is for automobile use.

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.

So to reduce the environmental hazards only way is to use energy in the way it will not harm environment.

What is Green Engine ?

Green engine is the Internal Combustion engine with some or major modifications in its parts and design. The Green engine as it is named for the time being is a SIX PHASE ENGINE, which has

a very low exhaust emission, higher efficiency, low vibrations etc.

Apart from these features, is its uniqueness to adapt to any fuel which is also well burnt.

History:

The green engine was a British engine manufacture founded by Gustavus Green in Bexhill to produce engines of his design. It flourished especially as a designer of aeroplane engines during the first two decades of the 20th century.

The firm produced a range of water-cooled, mostly inline engines powered many pioneering British Aircraft.

Then the designs of engine for motorcycle and cars was developed in late 21st century taking the concept of Greens’ design techniques.

TECHNICAL FEATURES:

Direct air intake.

Satisfactory Air-Fuel Mixing: Green engine achieves the better air

fuel mixing than conventional engine

which in turn reduces the emission of harmful gases like carbon

monoxide.

Complete Combustion of Fuel: As better Air to Fuel ratio, we achieve

better combustion.Full Expansion: In

conventional engine, total energy of expansion

stroke is not converted into useful energy. But

green engine overcomes this problem and

recovers full expansion stroke and

saves fuels.

Limited parts and smaller size. Vibration free.

The most important characteristic is the

expansion ratio being much bigger than the

compression ratio

Principle and Construction of Green Engine:

Green engine is really evolutionary concept. Its construction is a lot varied from the conventional reciprocating engine. It consists of:• A pair of rotors –it contains a number of small

pot like containers• A set of vanes • Two air intake ports • Two spark plugs • Two fuel injectors

WORKING : Intake Compression Mixing Combustion Power Exhaust

Advantages: Small Size and light weight – causes better

performance. Near-Zero emission Smooth operation-Due to inherence of good dynamic and

static balance, the performance of the Green engine is as smooth as an electric motor.

Multi Fuels- Due to six phases of working principle, super air fuel mixing process and constant volume combustion with controllable time, the Green engine becomes the only real multi-fuel engine on our planet; any liquid or gas fuels can be burnt well. Also it would be ideal to coal powder if special anti-wearing material is employed.

Low cost engine Lower exhaust temperature. i.e. low heat loss in

flue gases. Limited parts - There are only some dozens of parts

easy to be manufactured in the engine structure. Due to rotary nature green engine performance is

much better. Higher efficiency Less noisy and less vibrations and hence highly

efficient.

Applications:1. Like normal engine green engine can be employed in automobiles and in aircrafts, too.2. Engineering applications.3. Military use.4. Mines.5. Electrical Generators.6. Ships and submarines.

1. GREEN ENGINE PROTOTYPE 2. A GREEN ENGINE IMPLIMENTED IN GENERATOR

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

The Green engine's prototypes have been recently developed, and also because of the unique design, limitations have not been determined to any extent. But even in the face of limitations if any, the Green engine is sure to serve the purpose to a large extent.

Pollution is minimized by green engine.

It’s a new revolutionary engine technology.
