Evaluation of Tribological Properties of Cotton Seed Oil Based Lubricant Using Additives for IC Engine Application

Abstract

The evaluation of tribological properties of cottonseed oil-based lubricant with additives for internal combustion (IC) engine applications was conducted to assess its potential as an alternative to conventional petroleum-based lubricants. Cottonseed oil, a renewable bio-lubricant, was selected for its environmentally friendly nature, biodegradability, and favourable lubrication characteristics. Various additives, including anti-wear agents, friction modifiers, and antioxidants, were incorporated to enhance the performance of cottonseed oil in engine lubrication. The tribological properties, such as friction coefficient, wear rate, and lubrication film strength, were studied using a four-ball wear tester, pin-on-disc tribometer, and engine testing. Results showed that cottonseed oil-based lubricant with the selected additives exhibited promising wear protection, reduced friction, and improved oxidation stability compared to pure cottonseed oil and conventional mineral oil lubricants. The combination of the additives significantly improved the overall performance, making it a viable candidate for engine applications, with the potential for reduced environmental impact and enhanced fuel efficiency. Further studies on long-term engine performance and durability are recommended for comprehensive evaluation.
