在发动机台架上进行了陶瓷基颗粒氧化催化器（POC ）应用于轻型柴油机后处理系统的试验研究，并与金属基POC进行了对比。试验结果表明：在POC体积、目数及涂层性质一致的情况下，陶瓷基POC在ESC测试循环中的平均排气背压要较金属基POC低约15％；在ESC及ETC排放试验中，装配陶瓷基 POC及金属基 POC的发动机气态污染物排放值接近，陶瓷基POC颗粒排放是金属基POC的1．75倍（ESC）和1．5倍（ETC），但所有测试结果均满足国Ⅳ法规要求；金属基POC的最大颗粒承载量约是陶瓷基 POC的1．5倍；由于内部结构的不同，陶瓷基POC在抗烧损能力上要强于金属基POC。

The application test of ceramic-based POC in light-duty diesel engine was carried out on an engine bench test and was compare with that of the metal-based POC .The results showed that the average exhaust back-pressure of ceramic-based POC in ESC cycle was about 15% lower than that of metal-based POC under the same volume ,mesh and coating .The emission results of gaseous pollutants for both POCs were almost the same in ESC and ETC cycles ,but PM emissions of ceramic-based POC was 1 .75 and 1 .5 times of that for metal-based POC in ESC and ETC respectively .All the emission results could meet the State IV emission standards .The maximum carrying amount of metal-based POC was 1 .5 times of that for ceramic-based POC . In addition ,the ceramic-based POC had stronger anti-damaging ability than metal-based POC due to the different inner struc-tures .
