TABLE OF CONTENTS:

TABLE OF CONTENTS Abstract Introduction Technical features Construction and Working Advantages Conclusion Reference

ABSTRACT :

ABSTRACT The green engine is one of the most interesting discoveries of the millenium This engine is a pistonless one Variable compression ratio,direct air intake,direct fuel injection, multi-fuel usage etc It has comparitively high efficiency and exhaust emissions are nearly zero Prototypes of the engine have been developed Generators have been produced with the green engine

Slide 4:

The green engine is an actual six phase internal combustion engine with much high expansion ratio It has extremely high thermal efficiency It is light and small Low cost Complete burning

INTRODUCTION:

INTRODUCTION Coal, petroleum, natural gas, water and nuclear energy are the five main sources of energy The consumption of petroleum constitutes 60 percent of energy from all sources Green engine is a 6 phase engine which has a very low exhaust emission, high efficiency, low vibrations etc…. Its uniqueness to adapt to any fuel which is also well burnt

TECHNICAL FEATURES:

TECHNICAL FEATURES The green engine is an actual 6 phase internal combustion engine The six phases are………… Intake, compression, mixing, combustion, power and exhaust The features are……… Direct Air Intake Strong Swirling Sequential Variable Compression Ratio

Slide 8:

Direct fuel Injection Super Air-Fuel Mixing Lowest Surface to Volume Ratio Controllable Combustion time High Expansion Ratio Vibration Free Modular Design Limited parts Small size

CONSTRUCTION AND WORKING:

CONSTRUCTION AND WORKING The term phase is used instead of stroke is actually associated to the movement of piston But this engine has no piston The six phases are : Intake , compression, Mixing, Combustion, power and exhaust The engine has a set of vanes, a pair of rotors having a no: of small pot like containers The engine also contains two air intake ports, and a pair of fuel injectors and spark plugs

Slide 10:

1. Intake The air arrives to the engine through the direct air intake port in the absence of an air inlet pipe, throttle and inlet valves 2. Compression The rushing air from the duct is pushed by the blades into the small chambers in the rotor 3. Mixing In this phase the fuel mixes well with the compressed air This is for the deletion of CO emission

Slide 11:

4. Combustion In this phase chamber rotates towards the end of its path A spark flies from the plug into the air-fuel mixture 5. Power The expanded gas rushes out of the chamber through narrow opening 6. Exhaust As thermal energy is fully utilized, the exhuast gases bring less heat energy

ADVANTAGES:

ADVANTAGES Small Size and Light Weight Limited parts High efficiency Multi-Fuels: any liquid or gas fuels.eg: Methanol

Slide 15:

Near-Zero Emissions Smooth Operation Fast Accelerating Response Quietness and Low Exhaust Temperature Ideal to Hydrogen Fuel Highly Reliable Low cost

CONCLUSION:

CONCLUSION The Green engine prototypes have been recently developed It has unique design The limitations have not been determined to any extent The Green engine is serve the purpose to a large extent
