Engine Cooling System & Processing

Purpose: The combustion of fuel and air inside the engine produces enormous heat, only a part of which is converted to mechanical energy to drive the vehicle and the rest is left to engine body and exhaust for removal. High speed driving of  today’s engine can produce enough heat to melt an average engine in 20 minutes. All other parts of the engine also may run at very high temperature, much above the normal boiling temperature of water. The purpose of automotive engine cooling system is to control the engine< metal temperature within safe limits by removing excess heat produced by the combustion. When metal temperatures are not controlled by adequate cooling the consequences are lubrication failure and serious engine damage.

The enormous heat generated in combustion chamber utilizes only one-third of it to convert into mechanical energy for driving the vehicle, one-third is removed through exhaust gas and the remaining one-third is released to the engine body which eventually heats up the vehicle. The liquid cooling medium flowing through the cooling system absorbs this heat and dissipates to the atmosphere through radiator
