Anti-wear characteristics of jatropha trimethylolpropane (TMP) ester

This paper presents the experimental results from an evaluation of the wear prevention characteristics of a jatropha oil-based trimethylolpropane (TMP) ester using a four-ball machine (ASTM D4172). The load, speed and lubricant sample temperature were set at 40 kgf (393 N), 1200 rpm and 75 °C, respe...
