The document describes a new type of engine called the "Green Engine". The Green Engine has several key features: it uses direct air intake and fuel injection for efficient air-fuel mixing; it has a variable compression ratio for optimal performance; and it is designed for high efficiency and low emissions. The Green Engine works by compressing air-fuel mixtures in small combustion chambers and igniting them in a sequence to produce power pulses. It is more efficient and produces fewer emissions than conventional engines due to its design and ability to use various fuels. The Green Engine could be used in automobiles, aircraft, power generators and other applications. It is presented as a new, revolutionary engine technology.

3. INTRODUCTION
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.

4. TECHNICAL FEATURES
 Direct air intake
 Strong swirling
 Sequential variable compression ratio
 Direct fuel injection
 Super air-fuel mixing

5.  Controllable combustion time
 Constant volume combustion
 Multi power pulses
 High working temperature
 Higher expansion ratio

6.  Self adapting sealing system
 Vibration free
 Limited parts and smaller size
 Modular design

8. 1. Direct Air Intake:
 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.
 Highest volumetric efficiency.
 Engine produce a high torque of output
 The pump loss which consumes the part of engine power is
eliminated.
 Also fuel measuring facilities are built-in, and parts are saved.

9. 2. Strong Swirling:
 Swirling of air is take place until the gas port is
opened.
 This air is pumped into the combustion chamber.
 Air-fuel mixing and combustion process is formed
inside of the combustion chamber or in small pot.

10. 3. Sequential Variable Compression Ratio:
 Provide most suitable compression ratio for the
engine.
 Excellent combustion performance is attained.

11. 4. Direct Fuel Injection:
 Provide higher output
 Higher torque
 It also enhances the response for acceleration

12. 5. Super Air-Fuel Mixing:
 Sufficient 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.
 An ideal air-fuel mixture could delete CO emission.
 Centrifugal effect coming from both strong swirling and
rotation of the burner makes the air-fuel mixture more dense
near the spark plug.
 It benefits to cold starting and managing lean-burning.

13. 6. Controllable Combustion Time:
 sufficient controllable combustion time to match any
fuels.
 CO emission is zero
 High fuel usage rate (complete combustion of mixture)

14. 7. Constant Volume Combustion:
 Generate more energy
 allow the engine to have a stable combustion when the lean
burning is managed
 Water can be added to make higher working pressure and
drop down the combustion temperature
 Power is added; heat losses and NOx emissions are decreased.

15. 8. Multi-Power Pulses:
 The green engine operates on multi-power pulses with a small
volume of working chamber.
 Small volume of chamber only needs little space
 Compact structure and limited size
 Small amount of air-fuel mixtures being ignited on each
power pulse can greatly cut down explosion noise.

16. 9. High Working temperature:
 High heat resistant burner (ceramic)
 Operates without cooling
 It can eliminate the quenching which is the main source of
emission
 Reduce heat loss in combustion chamber

17. 10. High Expansion Ratio:
 Release the burnt gases with much more power
 Thermal efficiency of engine is greatly raised
 The noise and temperature of the exhaust are dropped

18. 11. Self-Adapting Sealing System:
 Eliminates a number of seal plates or strips to achieve gapless
seal
 More efficient
 Reliable sealing system
 Less friction

19. 12. Vibration Free:
 Vanes are counted in little mass
 Vanes operated symmetrically
 Very smooth performance of engine

20. 13. Limited Parts and Small Size:
 Few dozens of parts
 Easy to manufacture
 Low cost
 Compact structure
 Low weight (weight of the Green engine will be only 1/5 to
1/10 of the regular engine on the same output)

containers.
2. A set of vanes

4. Combustion
5. Power
6. Exhaust

25. 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.

26. 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.

27. 3. MIXING
 The injector sprays fuel into compressed air
 The fuel mixes well with compressed air
 Proper mixing leads to cut CO emissions
 In mixing phase we have ideal air fuel mixture

28. 4. COMBUSTION
 As the chamber rotates at the end of its path it
is positioned before spark plug
 Spark flies from plug into air-fuel mixture
 Denser Charge near spark plug enable lean
burning of charge

29. 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

30. 6. EXHAUST
 Exhaust gases bring along less heat energy
 Complete combustion leads to higher thermal
efficiency
 Poisonous gases like CO are absent

31. ADVANTAGES
 Small Size and light weight
 Limited parts
 Higher efficiency
 Multi Fuels

32.  Zero emission
 Smooth operation
 Highly reliable
 Low cost

33. APPLICATIONS
 Like normal engine green engine can be employed in
automobiles and in aircrafts, too.
 Engineering applications.
 Military use.
 Mines.
 Electrical Generators.
 Ships and submarines.

34. CONCLUSION AND SUMMARY
OF GREEN ENGINE:
 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.
 It’s a new revolutionary engine technology.
 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.
