Automotive cooling system

Automotive cooling system
A cooling system is necessary in a car for the components not to overheat. An effective
cooling system also gives the advantages of reducing the fuel consumption, retaining the
strength of the components, prevents wear caused by friction between piston and cylinder,
prevents high-temperature corrosions and reduces exhaust emission. An automobile cooling
system is also responsible for the heating of the passanger space in a car. Virtually all cars
produced today have liquid cooled systems. In the earlier years of the automobile it was not
uncommon with air cooled engines. Due to increased power output, and therefore increased
heat energy, air cooled engines has almost disappeared from the marked today. The heat
produced in a liquid cooled engine will ultimately be dispatched into the air, the difference
to an air cooled engine is that the heat is dispatched into the air indirectly.
A large proportion of the energy in the fuel is converted into heat, usually 65-75 %, and
almost half of the heat generated is being passed out by the exhaust gases. The remaining
heat generated from the combustion is being taken care of by the coolant and the oil.
A water pump transports the coolant between the engine block and and the radiator, and to other components that needs cooling/heat. The engine block and head contains
a water jacket where the coolant circulates
