초음파 개질 경유의 연소특성 = Combustion Characteristics of Diesel Engine Operated with Ultrasonically Reformed Diesel Fuel

다국어 초록 (Multilingual Abstract)

This paper describes the effects of the combustion characteristics as cylinder pressure, heat release rate, mass fraction burned, and combustion duration of ultrasonically reformed diesel fuels in the indirect injection diesel engine.
From the study, following conclusive remarks can be made.
1) The maximum combustion chamber pressures were increased by a maximum of 3㎏/㎠ in case of ultrasonically reformed fuel in comparison with that in the conventional fuel. In case of the retard of fuel injection timing, the maximum combustion chamber pressures of the ultrasonically reformed fuel showed nearly the same those of the conventional fuel.
2) Considering mass fraction burned, under operating with 2,000rpm and load 75%, the combustions of ultrasonically reformed fuel started a little early and ended rather early more than those of conventional fuel. When the injection timing was delay, the combustions of ultrasonically reformed fuel started a little later and ended rather early more than those of conventional fuel.
3) Within all the operation condition ranges of this experimental test, the ultrasonically reformed fuel decreased the combustion duration by a maximum of 7% and the ultrasonically reformed fuel delayed decreased the combustion duration by a maximum of 10% in comparison with conventional fuel.
