Abstract: The present paper gives an experimental study of the operation of a dual cylinder diesel engine working in dual fuel mode using jatropha oil biodiesel (JOBD) as the pilot fuel and producer gas as the primary fuel. JOBD is produced by esterification and transesterification process catalysed either by acids or bases followed by water wash and heating. Biodiesel require high temperature for ignition, so that is the only reason they are used in dual fuel mode. Utilization of biodiesel in vehicles reduces the excessive use of petroleum fuels and also reduces the emission of soothe particles. They also show positivity towards maintaining the balanced and sustainable growth of our economy. The experimental study shows the variation of emission characteristics of carbon dioxide (CO2). Carbon monoxide (CO), Hydrocarbon (HC), nitrogen oxides (NOx) and smoke opacity with respect to change in load. Along with the emission characteristics fuel consumption is also observed in order to appeal out the savings of the fuel. It has been found that while operating under different biodiesel blends and with varying load (Brake power) the emission levels of HC, CO,NO and smoke opacity have had a considerable reduction while CO2 emissions has increased
