Resumen

The recent use that has been given to bio-oil as an additive, in a commercial engine oil, raises the necessity to study its physical properties. The present study is aimed to obtain thermal properties of blends made with Jatropha-Curcas L. Oil, Crude, and Refined, at different concentrations using SAE40W oil (EO) as a lubricant base. By using photothermal techniques, thermal effusivity and diffusivity were obtained. The obtained results show that thermal effusivity increases from 455 Ws 1 / 2· m - 2· K - 1 to 520 Ws 1 / 2· m - 2· K - 1 as the percentage of additive increases as well, whereas thermal diffusivity values range from 7 × 10 - 8m 2· s - 1 to 10 × 10 - 8m 2· s - 1. In the present study, four balls test was used in order to obtain friction coefficient and wear scar values for studied samples, the obtained results point out that in general refined Jatropha-Curcas L. oil presents smaller wear scars than the crude one.
