An Experimental Study of Using Butanol Blending Oil in a Diesel Engine for Small Fishing Vessel

In this study, an experiment was conducted to investigate the engine performance, combustion characteristics, and emission characteristics, according to the operating conditions of the engine and the mixture ratio of diesel oil and butanol in a diesel engine. Combustion pressure, fuel consumption, smoke concentration, excess air ratio, intake and exhaust temperature were measured during this experiment. Using these data, the coefficient of variation of IMEP (indicated mean effective pressure) and the indicated fuel conversion efficiency were calculated for investigating the engine performance. The cylinder pressure was analyzed for pressure increasing rate and heat release rate. The experimental results of butanol blending oil were compared with the those of diesel oil. The optimum operating condition of engine and proper range of butanol blending rate could be identified without bad effect to the engine performance and the soot emission in this study.
