• 摘要：本文介绍一种以有机钡盐为主的复合型柴油添加剂,其主要成分是过氧化钡与环烷酸在焦化汽油中反应所生成的环烷酸钡。台架实验结果表明,该添加剂在柴油中添加量为0.5—1.5‰(重量,以钡计)时,取得了消烟率40.9—66.3％、节能0.36—4.42％的效果。行车试验也证明本添加剂具有优良的消烟节能作用,当添加量为1.0‰(重量,以钡计)时,平均消烟率为67.7％,节油5.21％。

• Abstract：The smoke suppressing effect of organic barium salt, a product of the reaction between barium bioxide and naphthenic acid in coking gasoline, as a diesel oil additive was studied. The dest test of engine showed that the smoke suppression rate in a range of 40.9 to 66.3 percent and the decrease of energy consumption from 0.36 to 4.42 percent could be achived when 0.05 to 0.15 percent (wt. by Ba) of the additive was added. The results of the vehicle driving test indicated that with 0.1 percent of the additive added, the smoke suppression rate was 67.7 percent and the fuel consumption decreased 5.21 percent.

• Key words：diesel oil additive  smoke suppressing effect  organic barium salt.
