PERFORMANCE EVALUATION OF TRIBOLOGICAL PROPERTIES OF COTTON SEED OIL FOR MULTI-CYLINDER ENGINE

A lubricant is a substance that reduces friction and wear by providing a protective film between two moving surfaces. Good lubricants possess the properties such as low toxicity, high viscosity index, high load carrying capacity, excellent coefficient of friction, good anti-wear capability, low emission into the environment, high ignition temperature. So tribology related problems can be minimized by proper selection of lubricant from wear consideration. Today, the depletion of reserves of crude oil, the growing prices of crude oil and concern about protecting the environment against pollution have developed the interest towards environment-friendly lubricants. Because of these the purpose of this work is to evaluate the anti-wear characteristics of cottonseed oil and to check the suitability of cottonseed oil as a lubricant for multi-cylinder engine.
