POTENTIAL OF COTTON SEED OIL AS AN ALTERNATING LUBRICANT 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 properties like low toxicity, high load carrying capacity, excellent coefficient of friction, high viscosity index, good anti-wear capability, low emission into the environment, high ignition temperature. Hence tribology related problems can be minimized by proper selection of lubricant. Now a day depletion of reserves of crude oil, growing prices of crude oil and concern about protecting the environment against pollution have created the interest towards environment-friendly lubricants. Hence paper work is related to check the suitability and to evaluate the anti-wear characteristics of cottonseed oil as a lubricant for multi-cylinder engine. Anti-wear testing is carried out on four ball testing machine as per ASTM D 4172. Image Acquisition System is used to check wear preventive characteristic of cottonseed oil by measuring wear scar diameter. https://journalnx.com/journal-article/2015062
