通过推进特性台架试验，研究了两种燃油添加剂分别对新、旧渔船柴油机排气排放污染物的影响，并引入加权系数计算加权净化率，通过对比分析，为渔民正确选择燃油添加剂提供参考依据。试验结果表明：两种添加剂在高负荷时的减排效果优于低负荷时，其中，添加剂B使旧柴油机HC、CO、NOx和烟度的降幅达到20．30％～40．35％，效果最佳。两种添加剂对旧机的加权净化率均优于新机，其中，添加剂A对旧机HC、CO、NOx和烟度的加权净化率分别为20．04％、12．53％、0．29％和19．38％；添加剂B对旧机HC、CO、NOx和烟度的加权净化率分别为36．46％、24．57％、23．99％和14．03％，减排效果最好。

The effects of two kinds of fuel additives on exhaust emissions of new and old fishing vessel diesels were studied through bench test with propulsion characteristic . It could provide useful information for fishermen to select fuel additives by comparing the weighted purification rate , which was calculated by weighted coefficient .The results showed that:better emission reduction was attained under the higher load compared with the lower load .The reduction rates of HC , CO, NOx and smoke on the old diesel with sample B had best performance , which ranged from 20 .30% to 40 .35%.Weighted purification rates on the old diesel were higher than that on the new diesel with sample 1 and 2.Weighted purification rates of HC , CO, NOx and smoke on the old diesel with sample A were 20.04%, 12.53%, 0.29% and 19.38%, respectively , while the weighted purification rates of HC , CO, NOx and smoke on the old diesel with sample B were much better than with sample A, which were 36.46%, 24.57%, 23.99%and 14.03%, respectively.
