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
