ERRASTI CABRERA, Michel et al. Characterization of a diesel engine fueled with Jatropha oil and diesel fuel blends. Energética [online]. 2013, vol.34, n.3, pp. 198-207. ISSN 1815-5901.

The present study aims to characterize the benefits of a diesel engine in terms of performance and ignition delay, operating under different loading regimes, using Jatropha oil and diesel fuel blends. We determined the speed exterior feature when using mixtures, and compared these results with those obtained during tests with standard diesel fuel, establishing the degree of involvement of the engine to replace some diesel fuel for Jatropha oil. There was a decrease in the torque and effective power, and increased specific fuel consumption by using a higher percentage of Jatropha oil in blends. Moreover, compared to diesel fuel, the ignition delay showed no significant variation by employing Jatropha oil and diesel fuel blends.
