ABSTRACT
This paper reports about the discharge characteristics of jatropha biodiesel blends along with producer gas from waste babul wood pieces in a dual-fuel direct injection diesel engine. The biodiesel blends were examined in both individual and dual-fuel modes at a constant gas flow rate of 21.69 kg/h at all loading conditions. From the results it may be concluded that oxides of nitrogen and smoke opacity reduce, whereas carbon dioxide (CO2), carbon monoxide (CO), and hydrocarbon (HC) increase for all test fuels in dual-fuel operation compared with that of a single style at different loading conditions. The fuel blends show better emissions than that of diesel in both the ways.
