Working of Green engineThe term phase is used instead of stroke is actually associated to the movement of piston
But this engine has no pistonThe 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

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

4.CombustionIn this phase chamber rotates towards the end of its path.A spark flies from the plug into the air-fuel mixture.
5.PowerThe expanded gas rushes out of the chamber through narrow opening.
6.ExhaustAs thermal energy is fully utilized, the exhaust gases bring less
heat energy.

Six phases of Green engine
Advantages of Green engine
Small size and light weightLimited partsHigh efficiencyMulti-fuelsNear-zero emissionsSmooth operationFast accelerating responseQuietness and low exhaust temperatureIdeal to hydrogen fuelHighly reliableLow cost
Applications of Green engine Like normal engine green engine can
be employed in automobiles and in aircrafts, too.
Engineering applications. Military use. Mines. Electrical Generators. Ships and submarines

Examples for Green engine
Kawasaki Green engine
Green engine in Aero plane
Conclusion
Green engine can work with large variety of fuels which makes it good choice for using nonconventional fuels like biodiesel.
Pollution is minimized by green engine.It’s a new revolutionary engine technology.
