IC Engine Cooling System By Air Cooling Method ##
---------------------------------------------

Heat engines generate mechanical power by extracting
energy from heat flows, much as a water wheel extracts
mechanical power from a flow of mass falling through a
distance. Engines are inefficient, so more heat energy enters
the engine than comes out as mechanical power; the
difference is waste heat which must be removed. Internal
combustion engines remove waste heat through cool intake
air, hot exhaust gases, and explicit engine cooling.Engines
with higher efficiency have more energy leave as mechanical
motion and less as waste heat. Some waste heat is
essential: it guides heat through the engine, much as a water
wheel works only if there is some exit velocity (energy) in
the waste water to carry it away and make room for more
water. Thus, all heat engines need cooling to operate.
