Performance Enhancement of Petrol Engine Using Lubricants Mixed with Nano-Particles

The performance and durability of petrol engines are strongly influenced by frictional losses and wear between moving components. Conventional engine lubricants provide adequate lubrication, but their effectiveness decreases under high temperature and load conditions. This study investigates the improvement of lubricant properties by mixing nano-particles with base engine oil. A stable nano-lubricant was prepared by dispersing nano-particles in controlled concentration using proper mixing techniques. The prepared lubricant was evaluated through friction test, wear test, flash point test, and fire point test to analyze thermal characteristics. The results were compared with those of conventional engine oil. Experimental findings indicate an increase in flash point and fire point values was observed, indicating improved thermal stability and safety at elevated temperatures. The study concludes that nano-particle blended lubricants can effectively enhance lubrication characteristics and support better engine reliability without requiring major mechanical modifications.
