What is green engine?Green engine is the internal combustion engine with

some or major modification in its part and design.The green engine is one of the most interesting

discoveries of the new millennium.The efficiency of this engine is high when compared

with the contemporary engines and also the exhaust emission are near zero.

The significance of the engine lies in the efficiency when the present world conditions of limited resources of energy are considered.

NEED TO INVENT

Environmental troubles

Major portion of fuels is burnt in the engines used for various purposes

Statistics of petroleum used

Energy crisis

Construction

1. A pair of rotors –it houses a number of small pot like containers

2. A set of vanes 3. Two air intake ports 4. Two spark plugs 5. Two fuel injectors

Working of green engine

(1)Intake (2)compression (3)Mixing(4)Combustion (5)Power (6)Exhaust

TECHNICAL FEATURS Direct Air intake Strong swirling Sequential variable compression Ratio Direct fuel injection Super air fuel mixing Controllable combustion time Constant volume combustion Multi power pulse High working temperature High expansion ratio Self adapting sealing system Vibration free Limited parts and small size

Comparison with conventional engine

• Low emission.• Low noise.• Low vibration.• Volumetric efficiency high.• Heat lose in exhaust gas is less.• Fuel feasibility less.• Torque and work output high.

Advantages of green engine

Small size and light weight

Limited parts High efficiency Multi- fuels Near zero emission Smooth operation

Ideal to Hydrogen Fuel Highly Reliable. Low Cost. Fast Accelerating

Response Quietness and Low

Exhaust Temperature

Disadvantages

• (a) They have less power and slower acceleration

• (b) They are more expensive to maintain

• (c) The parts that need repairs are more

Applications

• Like normal engine green engine can be employed in aircrafts.

• Engineering applications. • Military use. • Mines. • Electrical Generators • Ships and submarines

KAWASAKI’S GREEN ENGINE

ConclusionPollution is minimized by green engine.

it’s a new revolutionary engine technology.

It has unique design.

The limitations have not been determined to any extent.

The Green engine is serve the purpose to a large extent
