Many kinds of gasification systems are under development now. Heating value of gaseous fuels produced from solid fuel (wastes and biomass) gasification systems are as low as 1/10 of that of natural gas, and there is almost no established energy conversion methods for such low-BTU gases. Two kinds of low-BTU gas, one was produced by diluting from natural gas with nitrogen and the other was produced from the two-step pyrolysis/reforming gasification process were tested in a dual fueled diesel engine. In these experiments, power output could be kept constant by controlling the gas oil supply, when low-BTU gas supply changed. It was demonstrated that nearly 80% of oil supply could be replaced by low-BTU fuel gas with slight decrease of the thermal efficiency while significant reduction of NO_X emission was possible due to lower combustion temperature in the engine. Experimental results show that dual fueled diesel engines are quite feasible option for efficient utilization of low-BTU gases.
