摘　　要：通过对40°、90°、120°不同扩张管角度的稀土催化转换器进行流速分布试验和分析,表明40°扩张管结构的催化转换器气体流速分布明显优于90°、120°扩张管结构。通过柴油机烟度特性试验,表明改进入口管结构的催化转换器气体流速分布优于40°扩张管结构,其能够提高催化转换器的转换效率。The article analyzed the influence of different angle expansion tube structure on velocity of airflow in the rare earth converter,including 40°,90°,120°.According to the experiment,the 40°expansion tube of velocity distribution of airflow in converter is better than the 90°and 120°.From the test of diesel smoke intensity,the converter that be improved on the air-input structure is better than the 40°expansion tube of velocity distribution of airflow, it can improve the rate of conversion in converter.
