Abstract
This paper analyzed the individual characteristic of catalytic converter about light-off temperature test convert efficiency test and hot vibration test base on a mass of test data form two test methods, and it researched these characteristics with the catalytic converter from overseas. Then it researched the data different from the two tests.
Foundation the research result, the conclusion has given. How to improve our product level? During the research, we obtained some conclusions about that evaluate of catalytic converters. We believe that is beneficial to advance the kind product levels.
