This research investigated the physical properties of Jatropha oil to determine its viability as a clean and renewable source of lubricant oil. The study was performed using a four-ball tribotester, CCD camera, digital microscope and viscosity meter. The experiment was conducted using different temperatures (55, 75 and 105°C). The experiment was conducted of constant parameters as speed; load and time under the American Society for Testing and Materials (ASTM), number D 4172.The data included the evaluation of anti-wear, anti-friction and viscosity of Jatropha oil. To evaluate lubricant ability all results of this research were compared to findings regarding hydraulic oil as a mineral oil-based lubricant. The results showed that, under various temperatures Jatropha oil had better lubricant ability compared to hydraulic mineral oil. |
