Why Green Engine?
 Today the world is facing the major problems regarding energy
crisis .
 We are facing major environmental trouble due to harmful gasses which
are evolved.
 Major portion of fuel is burnt in the engine used in automobiles,
generators, power plants etc.
 Pollution is minimized by green engine.
INTRODUCTION

What is Green Engine?
 Green engine is an engine with some or major modifications in its parts
and design.
 The green engine is one of the most interesting discoveries
 The efficiency of the engine is high when compared to the contemporary
engines and also the exhaust emissions are near zero
 The significance of the engine lies in the efficiency
INTRODUCTION

 Direct air Intake
 Strong Swirling
 Sequential variable compression ratio
 Direct Fuel Injection
 Lowest surface to volume ratio
 High expansion ratio
 Vibration free
TECHNICAL FEATURES

 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 plug.
CONSTRUCTION AND WORKING

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 vales.
 Air filter is directly connected to the entry of the pipe.
2. COMPRESSION:
 The rushing air from the duct is pushed by the blades into the small
chambers in the rotor.
 Compressed air in swirling state mixed with fuel
3. MIXING:
 In this phase the fuel mixes well with the compressed air.
 This is for the deletion of CO emission.
WORKING

4. COMBUSTION:
 In this phase chamber rotates towards the end of its path.
 A spark files from plug into the air fuel mixture.
5. POWER:
The expanded gas rushes out of the chamber through narrow opening,
pushing the vane in process.
Sudden increase in volume ensures that more power is released.
6. EXHUST:
 As thermal energy is fully utilized, the exhaust gases bring less heat
energy.
WORKING

SIX PHASES OF GREEN ENGINE

COMPARISION WITH CONVENTIONAL I.C ENGINE

 Small Size and Light Weight
 Limited Parts
 High Efficiency
 Multi-fuels
 Near-zero Emissions
 Smooth Operation
 Low Cost
ADVANTAGES

 Like normal engine green engine can be employed in aircrafts
 Engineering applications
 Military use
 Mines
 Electrical Generators
 Ships and submarines
APPLICATIONS

 Pollution is minimized by green engine.
 It is a new revolutionary engine technology.
 It has unique design.
 The limitations have not been determined to any extent.
 Green engine can work with large variety of fuels which makes it good
choice for using non conventional fuels like biodiesel.
 The Green engine is serve the purpose to a large extent
