Application Research Of Effective And Sanitary Fuel Oxidant And Reducing The Emission Of Diesel Engine

Along with the development of economy all over the world, energy saving andenvironmental protection become the focus that people pay attention to increasingly. Diesel oiladditives can substitute petroleum fuel partly to save the fuel consumption;on the other handthey can improve the combustion performance in order to reduce the deleterious emission. Theresearch of diesel oil additives become one of the hotspots in many countries now.In this paper, the experiments of confecting composite oxidant have been done by usingthree different organic substances as materials, and the best proportion about the compositeoxidant and the blend fuel which composed by the oxidant and diesel have been found, thephysical and chemical characters of the composite oxidant and the blend fuel have beenanalyzed, the effect of different diesel oil/additive ratio on the performances of power, economyand emission have been compared, the combustion performance has also been researched. On the condition of not changing any frame of the diesel engine, the experimental resultsshow that the FHYJ can reduce the soot emission obviously, especially at middle and high load.The engine performance of power decreases a little at lower load, but it ameliorates a little atmiddle and high load. The emission performance has been partly improved, and the combustionalso has been ameliorated in some extent. The ignition delay becomes longer, and it increases asthe proportion of FHYJ increases. The combustion duration becomes shorter, and it increases asthe proportion of FHYJ decreases.
