COOLING SYSTEM

Fuel is burnt inside the cylinder of an internal combustion engine to produce power. The temperature produced on the power stroke of an engine can be as high as 1600 ºC and this is greater than melting point of engine parts.. The best operating temperature of IC engines lie between 140 F and 200 ºF and hence cooling of an IC engine is highly essential. . It is estimated that about 40% of total heat produced is passed to atmosphere via exhaust, 30% is removed by cooling and about 30% is used to produce power.

Purpose of Cooling

1. To maintain optimum temperature of engine for efficient operation under all conditions.

2. To dissipate surplus heat for protection of engine components like cylinder, cylinder head, piston, piston rings, and valves

3. To maintain the lubricating property of oil inside engine.

Methods of Cooling

1. Air cooled system

2. Water cooled system
