摘要：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。

Abstract：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 2 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 1 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 2 were much better than with sample 1, which were 36.46%, 24.57%, 23.99% and 14.03%, respectively.
