3. INTRODUCTION
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.
Compared to conventional piston engine operated on four phases, the Green
Engine is an actual six-phase internal combustion engine with much higher
expansion ratio.
 In green engine the priority is given to the complete mixing of fuel with the air
thereby causing its complete burning.

4. NEED TO INVENT
 Today, the world is facing serious pollution crisis due to the exhaust gases from vehicles
using petroleum-based fuel.
 The pollutants like HC, NOx occurs due to the incomplete combustion of fuel. These
pollutants are very harmful to human being causing various diseases.
 The “IEA Oil Market Report” forecasts worldwide average demand of nearly 96 million
barrels of oil and liquid fuels per day – that works out to more than 35 billion barrels a year,
of which about 50 per cent is used in communications and transportation.
 The world has 53.3 years left to find an alternative to oil before current proved reserves run
dry, according to “British Petroleum”.
 To counter this problem, the concept of green engine is introduced.
 Pollution is minimized by green engine.
 It is a multifuel engine; therefore the fuel crisis can also be overcome.

5. PRINCIPLE AND CONSTRUCTION OF
GREEN ENGINE
Due to six phase of working principle the priority is given to the complete mixing of fuel
with the air thereby causing its complete burning.
The six phases are INTAKE, COMPRESSION, MIXING, COMBUSTION, POWER AND
EXAUST.
It consist of :-
– A pair of rotors
– A set of vanes
– Two air intake ports
– Two spark plugs
– Two fuel injectors

WORKING OF GREEN ENGINE

8. 1. INTAKE
• The air is admitted directly inside the compression chamber.
• The air does not undergo any treatment before entry.
• The air filter is directly connected to the entry of the intake pipe.
• The amount of the air intake can be varied as per the fuel used.
• 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 air admitted in, then enters into the compression chamber.
• The compression chamber has variable area.
• The central disc having arms pushes the air in the compression chamber.
• The compression chamber is connected to the combustion chamber by a small
diameter duct which is tangent to the combustion chamber.
• So as arm pushes the air in the compression chamber the pressurized air is forced to
flow through this duct.
• As the air flow through it, the air is swirled very fast. The air thus enters the
combustion 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.
• The mixing assures the complete burning of the fuel.
• The super mixed charge is forced by the arm towards the spark plug.

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 burned products of the combustion are expelled out of the combustion chamber.
• The high pressure gases push the arm of the compression chamber causing work
output.
• The Sudden increase in volume ensure that more power is released or in other words,
the thermal energy is fully utilized.
• The power is obtained in the form of the power pulses.
• These pulses reduce the area of the engine.
• The power pulses also reduce the explosion noise.

13. 6. EXHAUST
• The burned gases are expelled out.
• The gases are first expanded in the expansion zone.
• The expansion ratio is more which ensures the maximum work output. Also the
maximum energy is gained from the gases.
• The temperature also reduces and hence an optimum utilization of the burned gases is
achieved.
• The burned gases after expansion are pushed into the exhaust pipe and released into
the atmosphere. Thus the six-phase cycle is completed.

14. TECHNICAL FEATURES
Direct Air Intake
Strong Swirling
Direct Fuel Injection
Lowest Surface to Volume Ratio
Controllable Combustion Time
High Working Temperature
High Expansion Ratio
Self-adapting Sealing System
Multi-power Pulses
Super Air-Fuel Mixing

15. ADVANTAGES
As Green Engine is very compact with multi-power pulses, the Size and Weight
could be only 1/5 to 1/10 of the conventional piston engines on same output.
The Thermal Efficiency of the Green Engine could be potentially as high as 65%,
even more if water add-in technology is to be considered.
Due to Six Phases of Working Principle, Super Air-fuel Mixing Process and Constant
Volume Combustion with Controllable Time the Green Engine becomes the only real
Multi-Fuels Engine on our planet; any liquid or gas fuels can be burned well.
With perfectly air-fuel mixture, complete combustion under lower peak temperature
and free of quenching effect, the Emissions of CO, HC and NOx could be near zero.
Due to inherence of good dynamic and static balance the performance of the Green
Engine is as smooth.
Limited parts, small in size, light in weight it means that it would be on the much
lower cost.

16. DISADVANTAGES
Not readily available
Still in experimental stages
Variation in smoke capacity

17. COMPARISON OF GREEN ENGINE

Torque and Work Output High Low

18. APPLICATIONS
The Green Engines could be used as the ideal power plants on a very wide range of
applications in:-
 Transportation & Communication
 Farm
 Mine
 Engineering
 Military uses
 Aircrafts
 Submarines

21. CONCLUSION
The environmental problems can be effectively overcome by the use of Green

It can use almost any type of fuel available.
It is superior to the conventional I.C. engine in terms of smooth operation, efficiency
and cost.
 Compared to conventional piston engine operated on four phases, the Green

expansion ratio.
Already it is being used in some of the application like aircrafts, ships and
locomotives. Research is going on for its effective use in wider range of transport
vehicles
