4. 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.

5. 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.

6. • 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

7. 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

8. WORKING
1. Intake
2. Compression
3. Mixing
4. Combustion
5. Power
6. Exhaust

9. 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

10. 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.

11. 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.

12. 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.

13. 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.

14. 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

15. 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

16. 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

17. DISADVANTAGES
• NOT READILY AVAILABLE
• STILL IN EXPERIMENTAL STAGES

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.
