1. The green engine is a new type of internal combustion engine that uses a six-phase pistonless design to achieve higher efficiency and nearly zero emissions compared to conventional engines. 2. It works by using strong swirling of air and fuel to enable direct injection and mixing, followed by constant volume combustion with a controllable time. 3. The green engine has advantages like small size, lower costs, ability to use multiple fuels, and reduced pollution compared to conventional engines.

3. 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 the engine is high when
compared to the contemporary engine and
also the exhaust emissions are zero.
• This engine is piston less one.

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

5. • Today world is facing major problems regarding
energy crisis.
• Along with this we are facing environmental trouble
due to increase in harmful gases due to combustion
of conventional energy sources.
• Pollution is minimized by green engine.
Need to Invent

6. Principle and Construction of Green
engine
• Due to six phases of working principle, super
air fuel mixing process and constant volume
combustion with controllable time.
• It consist of :-
1. A pair of rotors
2. A set of vanes
3. Two air intake ports
4. Two spark plugs
5. Two fuel injectors

7. Working
1. Intake
2. Compression
3. Mixing
4. Combustion
5. Power
6. Exhaust

8. 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
to the chamber

9. 2. Compression
• The rushing air from the duct is pushed into
small chamber in the rotor which volume is
very small.
• Compression obtained by such procedure is
satisfactory
• The Compressed air is in swirling state, ready
to be mixed with the fuel which will be
injected into the chamber.

10. 3. Mixing
• As the chamber comes in front of the fuel
injector, the injector sprays fuel into
compressed air .
• The fuel mixes well with compressed air.
• Proper mixing leads to cut CO emissions
• The Mixing phase has enough time to
produce an ideal air-fuel mixture as the spark
plug is positioned towards the other end of
the rotor.

11. 4. Combustion
• The charge is ignited by the spark plug. The
combustion time can be varied to burn different
grade of fuels.
• The controlled combustion time gives the
complete burning of the charge. The emissions
are greatly reduced.

12. 5. Power
• The Expanded gases rushed out of the
chamber through narrow opening
• Pushing the vane in the process
• The Sudden increase in volume ensure that
more power is released or in other words, the
thermal energy is fully utilized.

13. 6. Exhaust
• As the thermal energy is fully utilized, the
exhaust gases bring along comparatively less
heat energy
• And because of Complete combustion leads to
higher thermal efficiency
• Poisonous gases like CO are absent in the
exhaust

14. Technical features
• Direct air intake
• Strong swirling
• Sequential variable compression ratio
• Direct Fuel Injection
• Super air fuel mixing
• Constant Volume Combustion
• Controllable combustion time
• High Expansion Ratio

15. Advantages
• Small Size and light weight
• Limited parts
• Higher efficiency
• Multi Fuels
• Smooth operation
• Quietness and low exhaust temperature
• Low cost
• Reduce to risk of some health problems

16. Disadvantages
• Not readily available
• Still in experimental stages

17. Comparison of Green Engine with
conventional engines
GREEN ENGINE CONVENTIONAL ENGINE
Emission Low High
Noise and vibration Less More
Volumetric efficiency High Low
Heat loss in exhaust gas Less High
Torque and work output High Low

18. Applications
1. Research is going on for its effective use in
wider range of transport vehicle Engineering
application
2. Aircrafts

19. 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 minimized by green engine.
3. it’s a new revolutionary engine technology.
