AUTOMOTIVE COOLING SYSTEMS FOR INTERNAL COMBUSTION ENGINES – An Introduction
Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into
motion. Modern automotive internal combustion engines generate a huge amount of heat. It has
been stated that a typical average-sized vehicle can generate enough heat to keep a 5-room house
comfortably warm during zero degree weather.


The Necessity of having a good Engine Cooling System


An Engine Cooling System is a system that controls the engine temperature, is known as a
cooling system. The cooling system is provided in the IC engine for the following reasons:


The temperature of the burning gases in the engine cylinder reaches up to 1500 to 2000°C,
which is above the melting point of the material of the cylinder body and head of the engine.
(Platinum, a metal which has one of the highest melting points, melts at 1750 °C, iron at
1530°C and aluminium at 657°C.) Therefore, if the heat is not dissipated, it would result in
the failure of the cylinder material.


Due to very high temperatures, the film of the lubricating oil will get oxidized, thus
producing carbon deposits on the surface. This will result in piston seizure.


Due to overheating, large temperature differences may lead to a distortion of the engine
components due to the thermal stresses set up. This makes it necessary for, the
temperature variation to be kept to a minimum.


Higher temperatures also lower the volumetric efficiency of the engine.
The two main requirements of an efficient cooling system are:


1. It must be capable of removing only about 30% of the heat generated in the combustion
chamber. Too much removal of heat lowers the thermal efficiency of the engine.


2. It should remove heat at a fast rate when the engine is hot. During the starting of the engine, the
cooling should be very slow so that the different working parts reach their operating
temperatures in a short time.
