3. 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.

4. 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.
