Cooling: Why Cooling is required in Internal Combustion Engine?
It has been practically found that out of total heat generated by internal combustion engine due to combustion of fuel, only 30% of heat is converted in useful work, out of remaining 70% about 40 % is carried by exhaust gases into the atmosphere during exhaust stroke. The rest of 30% must be passed to atmosphere by some suitable arrangement.
Here we find the necessity of cooling. In addition to overheating, large temperature differences may lead to distortion of the engine components due to set up of thermal stresses. If the cooling system is not provided to internal combustion engine, the lubricating oil film would break down and the lubricating oil will decompose to give gummy and carbon deposits.
