- ABSTRACT Biomass gasification is an energy conversion technology that converted biomass into synthetic gas, syngas, such as CO, H2 and CH4 which can be employed as fuel that environmentally sound. Syngas has potential to be used as diesel engine fuel. This research was done to analysis the potential reduction of diesel fuel consumption when the diesel engine is simultaneously fueled by diesel fuel and syngas in dual fuel system. The research was done by running the diesel engine in various speeds, i.e. 1000, 1500, and 2000 rpm. The syngas was inputted into the engine via air intake of the engine. The input rate of syngas as well as air was set by varying the air intake valve at 1⁄2, 3⁄4, and full positions. Performance parameter determined was consumption reduction of diesel fuel. Cost analysis was also done to know the treatment effect on the reduction of diesel fuel cost. Experimental result shows that rotational speed of the engine and input rate of syngas and air were significantly affect in the reduction of diesel fuel of dual fuel system diesel engine. The faster rotational speed and the lesser air input the bigger reduction of diesel fuel. At 2000 rpm and 1⁄2 of air intake wide of valve the reduction of diesel fuel consumption was 335 ml/hr. One liter of diesel fuel was equal as 8.33 kg of wood charcoal. Keywords: gasification, biomass, diese enginel, dual fuel system
