This document discusses green engine technology, which aims to modify internal combustion engines to increase efficiency and reduce emissions. It provides background on the need to develop green engines due to rising energy consumption and environmental issues. The key features of green engines are described, including direct fuel injection, variable compression ratios, and optimized combustion. The construction and 6-phase working principle of a prototype green engine are outlined, involving air intake, compression, mixing, combustion, power, and exhaust phases. Benefits over conventional engines cited are higher efficiency, lower emissions and fuel usage, and improved performance. Potential applications include automobiles, aircraft, generators, and more.

2. WHAT IS GREEN ENGINE???
 Green engine is the internal combustion engine with
some or major modification in its part 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 with
the contemporary engines and also the exhaust emission
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. NEEDTOINVENT….
 Today 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 above 50% is automobile use.

4. ENERGY CRISIS………
WORLD MARKETED
ENERGY CONSUMPTION
1980-2030

5. TECHINICAL FEATURES
• Direct intake
• Strong swirling
• Sequential variable
compression Ratios.
• Direct fuel injection
• Super air fuel mixing
• Lowest surface to volume
ratios
• Constant volume
combustion
• Controllable combustion
time
• Multi power pulses
• High Working
Temperature
• High expansion ratios
• Self adapting sealing
system
• Vibration free
• Modular design
• Limited parts and small
size

6. CONSTRUCTION
It is a six phases engine.
Stroke is related to piston, This
engine do not contain piston
hence stroke is replaced by
phases.
It contains two intake ports ,
two compression chamber,
two mixing chamber , two fuel
injector ports, two spark plugs
and two exhaust as shown in
the figure.

7. Working…
1.INTAKE.
 Air arrives to engine
through air intake port.
 A duct is provided on the
side wall of the vanes and
rotors.
 When air moves through
the duct a 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 by the blades the
small chambers in the rotor.
 Compression obtained by such
procedure is satisfactory.
 Compressed air in swirling
state mixed with fuel.

8. WORKING..
3 MIXING
 The injector spray fuel
into compressed air.
 The fuel mixes with
compressed air.
 Proper mixing lead to
cut CO emissions.
 In mixing phase we
obtain almost ideal air
fuel mixture.
4 COMBUSTION
 As the chamber rotates
at the end of the path
before spark plug.
 Spark flies from plug to
air- fuel mixture.
 Denser charge near
spark plug enable lean
burning of charge.

9. Working..
5 POWER
 The expanded gas runs
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
 As thermal energy is
fully utilized, the
exhaust gas bring less
heat energy.

10. ADVANTAGES
 Small size and light
weight.
 Limited parts.
 Multi-fuels: any liquids
or gas fuels. Ex:
Methanol, Bio-Diesel
etc.
 High efficiency.
 Near zero emissions.

11. ADVANTAGES
 Smooth operation.
 Fast acceleration
response.
 Quietness and low
exhaust temperature.
 High reliability.
 Low cost.

12. • LIKE NORMAL ENGINE

14. • Low emission.
• Low noise.
• Low vibration.
• Volumetric efficiency high.
• Heat lose in exhaust gas is
less.
• Fuel feasibility less.
• Torque and work output
high.
Conventional engine
• High emission.
• High noise.
• Low vibration.
• Volumetric efficiency low.
• Heat lose in exhaust is high.
• Fuel feasibility high.
• Torque and work output
low.

15. APPLICATIONS
• Like normal engine
green engine can be
employed in
automobile and aircraft.
• Engineering application.
• Military use.
• Mines.
• Electrical generator.
• Ship and submarine.
