Experimental Investigation of Coconut and Palm Oils as Lubricants in Four-Stroke Engine

In the present work the evaluation of coconut and palm oil as lubricants in four-stroke engine was carried out and the performance was compared with commercially available engine oil. The tribological properties of oil samples collected from the engine at regular interval were evaluated by means of...
