催化转化器是汽油机的机后净化装置,它可以降低尾气中的CO、HC及NO_x的含量,保护环境,满足愈来愈严的机动车排放法规要求。但是,目前由于我国汽油车车型多、杂、技术状况参差不齐,催化转化器品质不稳定及驾驶员使用不当等原因,利用安装催化转化器来降低排放的效果并不好,许多车型的排放达不到ECE 83-01(欧 1)法规限值,甚至出现催化转化器
Catalytic converter is a post-engine purifying device of gasoline engine. It can reduce the content of CO, HC and NOx in the exhaust gas, protect the environment and meet the increasingly stringent vehicle emission regulations. However, at present, due to the large number of gasoline vehicles in our country, miscellaneous and technical conditions, the unstable quality of catalytic converters and the improper use of pilots, the effect of using catalytic converters to reduce emissions is not good and emission of many vehicles The ECE 83-01 (EU 1) regulatory limit is not met or even a catalytic converter is present
