Experimental Analysis of Effect of Bio-lubricant Between Tribological Systems of Piston Ring Under the Jatropha Oil

In an Engineering scenario, it is necessary to increase the efficiency and life of every component in the machine. A particular vehicle is selected based on its working ability to increase the efficiency and life span. In this project, I have chosen the piston ring material with the Jatropha as lubricating oil to increase the efficiency and the life span of the engine. The life span and working ability are governed by the friction and wear characteristics of components of the engine of the vehicle. The life span of any vehicle is calculated by the life of its sensitive part that is susceptible to wear. In tribological system “piston -ring-liner” observed 45–55% of frictional mechanical losses. To reduce such losses, lubrication performs a vital role. Lubricant is the main part of lubrication to maintain reliable functions of the machine, provide smooth operations and chances of failure is less. Crude oil is a vital source to manufacture lubricant. But in today’s condition, the prices of crude oil increasing and depletion of crude oil reserves in the world, and global concerning protecting the environment from pollution have renewed interesting developing and using environment-friendly lubricants derived from alternative sources.
