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

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
