Investigation on jojoba biodiesel and producer gas in dual-fuel mode

ABSTRACT

This paper exhibits the emission characteristics of a diesel engine fueled with jojoba oil methyl ester and its blends (10, 20, and 30%) utilizing the groundnut shell producer gas. Emission parameters of jojoba biodiesel were tested in dual-fuel mode at constant gas flow rate of 22.72 kg/h. Various oil characterizations like kinematic viscosity, specific gravity, flash and fire point, oxidation stability, calorific value, cetane number, sulfur content, and so on and emission parameters such as carbon monoxide (CO), carbon dioxide (CO₂), hydrocarbons (HC), nitrogen oxide (NO_x), and smoke emissions are were taken into account. From the experimental values it can be resolved that there is substantial advancement in both oil characterization and emission parameters for minor blends of jojoba oil methyl esters in comparison to those of neat diesel.
