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.
