What Is GREEN ENGINEGreen engine is the internal combustion engine with

some or major modifications in its parts 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 to the contemporary engines and also the exhaust emissions 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 ENVENTToday world is facing the major problems regarding energy

crisis.

Along with this we are facing major environmental trouble due to increase in harmful gases which are evolved from nowhere else but the combustion of these conventional energy sources.

Major portion of fuels is burnt in the engines used for various purposes like main automobiles, generators, power plants etc.

Statistics show that, the daily consumption of petroleum all over the world today is 40 million barrels, of which about 50 percent is for automobile use.

CONCLUSIONThe Green engine„¢s prototypes have been recently

developed, and also because of the unique design, limitations have not been determined to any extent.

But even in the face of limitations if any, the Green engine is sure to serve the purpose to a large extent.
