摘要

摘要: 为研究燃油中不同的硫质量分数在柴油机内的燃烧状况及对柴油机排气成分的影响, 通过对比试验, 利用化学发光法、定电位电解法、磁气风式法、Galvanic Cell Type法及过滤称重法分别测定了硫分质量分数为0、1.5、3.0和5.0时的NO_x、SO_x、CO_x、残碳颗粒(DS) 及可溶性有机物质(SOF) 的浓度及对着火延迟的影响。实验结果表明燃油硫质量分数对柴油机燃烧状况有着一定程度的影响, 随着燃油硫质量分数的增加, 燃油消耗量也随之增加, 在硫质量分数3.5%范围内对燃油消耗量的影响最为显著, 随后处于平缓, 并从而影响排烟温度。CO随硫质量分数的增加而明显上升, 但CO₂基本保持不变; 随着硫质量分数的增加, SOF生成量反而下降, 而DS的生成量则随之上升; NO_x含量随着燃油中硫分质量分数的增加而呈下降的趋势。

Abstract: In order to study engine burning conditions and the harmful matters of engine exhaust gas when diesel oil has different sulfur contents, the harmful matters, such as NO_x, SO_x, CO_x, DS and SOF, were measured by chemiluminescence detector, electro chemical cell, magnetic type, galvanic cell type, filtration and weight method when the sulphur contents of fuel oil were 1%, 1.5%, 3.0% and 5.0% respectively.Test result shows that the different sulfur contents of diesel oil have obvious effect on the burning condition and exhaust gas temperature of marine engine, the fuel oil consume ratio increases with sulfur content increase, and it reaches the maximum value when sulfur content is within 3.5%, CO content increases with sulfur content increase, but CO₂ content is invariable, SOF content and NO_x content decrease with sulfur content increase, but DS content increases.
