Definition

Green Engine is a six phase internal engine having a very higher expansion ratio ,higher thermal effeciency,with nearly zero emissions , quietness ,light and small in size ,lower cost with a capability of burning various kinds of fuels.

Technical features

Direct air intake

Strong swirling

Sequential variable compression ratio

Direct fuel injection

Super air fuel mixing

Controllable combustion time

Constant volume combustion

Multi power pulses

Higher expansion ratio

Self adapting sealing system

Vibration free

Limited parts and smaller size

Construction

1. A pair of rotors –it houses a number of small pot like containers

2. A set of vanes 3. Two air intake

ports 4. Two spark plugs 5. Two fuel injectors

Working

1. Intake2. Comprssion 3. Mixing 4. Combustion5. Power6. Exhaust

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 into small chamber in the rotors

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

Propere mixing leads to cut CO emissions

In mixing phase we have 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 into air-fuel mixture

Denser Charge near spark plug enable lean burning of charge

5. Power

The Expanded gases rushed 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

Exhaust gases bring along less heat energy

Complete combustion leads to higher thermal effeciency

Poisonous gases like CO are absent

Advantages

Small Size and light weight

Limited parts

Higher effeciency

Multi Fuels

Zero emission

Smooth operation

Highly reliable

Low cost

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.

Conclusion and Summary of Green Engine:

1. Green engine can work with large variety of fuels which makes it good choice for using nonconventional fuels like biodiesel.2. Pollution is minimised by green engine.3. it’s a new revolutionary engine technology.
