Abstract—The objective of proposed work is to present about engine performance and emissions analysis of a diesel engine using the diesel fuel and the supercharging producer gas in dual fuel mode compared with only diesel fuel mode. Producer gas is generated from a small downdraft gasifier 75 kW using a charcoal as the primary fuel. Results of performance and emissions at engine speed 1,600 rpm show that using diesel fuel and supercharging producer gas at various flow rates in dual fuel mode increase the electrical power and electrical efficiency and decrease the energy consumption. Carbon monoxide, hydrocarbons and black smoke emissions increase with increasing producer-gas flow rate. Compressing producer gas at 125 lpm indicates that there is the highest diesel saving at 40% on engine speed of 1,200 rpm.
Index Terms—Producer gas, supercharging, performance, emissions.
