Research ArticleOpen accessIn the abstractExperimental Study of Diesel Engine Generator Performance and Emission Characteristics Using a Mixture of Jatropha Oil and Rubber Seed Oil Biodiesels Along a Two-Step TransesterificationFana Gebremedhin Gebremichael, Joao Fernando ChidamoioThis study investigates the performance and emission properties of engine-generator powered using various dual biodiesel mixes prepared from two inedible feedstock jatropha and rubber. Jatropha and rubber oils had high acid values, which were 13.96 and 27.91 mg KOH/g, respectively. Therefore, a two-step transesterification process was conducted to lower the acid value to 0.28 and 0.42 mg KOH/g for jatropha … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 1 Jul 2024 · 5,124 accessesView PDFCite
