The present investigation elaborates on the exhaust emission and diesel fuel savings from a multicylinder diesel engine operated in dual fuel mode utilizing salmon biodiesel and sesame wood generated producer gas at different loads (0, 2, 4, 6, 8, and 10 kW) under an optimum producer gas flow rate of 19.72 kg/h. The results of this investigation depicted that both nitric oxide and smoke emission were reduced, while carbon monoxide, carbon dioxide, and hydrocarbon emission increased for dual mode in contrast to single fuel operating mode. Increase in biodiesel blend percentage shows a reducing curve for all the emission parameters in comparison to diesel fuel for all test conditions in dual fuel mode. Therefore, for optimum producer gas flow rate of 19.72 kg/h, it might be inferred that sesame generated producer gas with salmon biodiesel may be able to substitute for the conventional diesel for reducing greenhouse emission without much engine modification.
