Friction and Wear of <i>Jatropha curcas</i> Oil Using a Four Balls Tester

Abstract

Jatropha curcas oil (JCO) is a good option as renewable energy for biodiesel and as lubricant feedstock. In México, the JCO is widely distributed in more than 15 states. This work describes the characterisation of Jatropha curcas oil as additive in engine oil (EO) blended mixtures. The EO and JCO were separately tested using a four balls test rig at 100%. The JCO was added and mixed as an additive to the EO too at 5%-95%, 10%-90%, 15%-85%, 20%-80%, and 50%-50%. The results have shown a steady friction coefficient for the testes carried out at different loads for the different mixtures. The friction coefficients were lower compare to the friction coefficients from the oil engine. Nevertheless, the wear scars were bigger when JCO was used. The results from the oil mixtures showed good potential for the JCO to be used as an additive.

Study of Jatropha curcas Linn and Olea europaea as Bio-Oil Lubricant to Physical Properties and Wear Rate

“…The modernization of Pongamia and Jatropha curcas oil (JCO) as direct cutting fluids has great potential for use as environmentally friendly and biodegradable metal cutting fluids [8]. JCO provides excellent lubrication reducing the coefficient of friction [9]. The lubrication capacity is important for friction between the tool and the work piece and hence affects the tool wear behavior and the surface quality of the work piece just as JCO can be used as metalworking fluids [10].…”
