The document discusses the green engine, which is an internal combustion engine modified to increase efficiency and reduce emissions. It notes that green engines are more efficient than contemporary engines and produce near-zero exhaust emissions. This makes them significant given current energy and environmental challenges. The document outlines the need to invent green engines to address issues like energy crisis and harmful gas emissions from conventional engines. It provides details on green engine working, technical features, advantages, examples of different green engine applications, and concludes that green engines will help serve the purpose of addressing current energy and environmental problems, even if some limitations remain unknown.

2. What Is GREEN ENGINE
 Green 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.

3. NEED TO INVENT
 Today 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.
