Effect of Density and Viscosity on Injection Characteristic of Jatropha - waste Cooking Oil Biodiesel Mixture.

Biodiesel has an important role in the world of transportation and its existence is taken into account. So availability biodiesel fuel future will be difficult to eliminate must continue fulfilled. Therefore, it necessary innovate increase fuel. can made from biological materials includes renewable energy as a substitute for diesel oil. The production this study jatropha waste cooking oil raw materials. This aims determine effect density viscosity on injection characteristics jatropha-waste mixtures (1:4 4:1) various B5-B40 fuels. Production through degumming, esterification transesterification processes. results showed that mixed with 1:4 level B15 4:1 B10 complied SNI 7182-2015 standards. higher values biodiesel, narrower spray angle longer penetration
