Next several testing methods were proposed from the principle of disabled TWC,the performance of engine bench testing,the National Standard. Also the tests including aging test,light-off test,OSC test and vehicle matching verification test were all carried out.
其次从三效催化转化器的失效机理入手,参考催化器的台架性能试验和有关国家标准,提出临界催化器制备过程中各种试验方案并进行大量的试验,其中包括催化器起燃温度试验、老化试验,催化剂储氧量测试,整车匹配验证试验。
