Lubrication System in IC Engine: Learn Different Parts & Methods of Lubrication

By far, the most commonly used lubricant used in these applications is mineral oil.

The purpose of lubrication in an IC engine is to reduce friction and wear between the moving parts, cool the engine components, seal the gaps between piston rings and cylinder walls, clean the engine parts from dirt and carbon, and cushion the shocks and noise from the engine operation.

Its primary function is to reduce the friction between moving components which helps to lower the rate of wear and tear in these engine components. It also has other functions such as providing a cooling effect, cushion effect, cleaning action, sealing action and reducing noise.

By far, the most commonly used lubricant used in these applications is mineral oil.

Examples of lubricating agents include magnesium stearate (most widely used lubricant), stearic acid, hydrogenated vegetable oil, mineral oil, and talc (generally requires high concentrations of 5%).
