摘　　要：针对北京切诺基四缸多点喷射轻型车,本文研制成功了一种催化转化器。整车十五工况的试验表明:所研制的催化转化器对于降低原车的排放具有明显的作用。进一步的模态分析揭示了所研制的催化转化器的排放特性。初步的耐久性试验表明所研制的催化转化器具有实用性。A kind of catalyst system has been successfully developed for Beijing Cherokee with multipoint injection. The 15-mode test showed that this kind of catalyst can greatly reduce exhaust emissions. The further modal analysis revealed the emission performance of the catalyst and the tentative durability test indicated its practicability.
