WebMar 8, 2004 · Having tuned the reaction parameters through a light-off test and estimated oxygen storage capacity through an oxygen storage test, we ultimately tuned the model in a vehicle test (with Bags 1 and 2, FTP 75). As a result, the simulated cumulative tailpipe emissions are within ±25 percent of the test results. WebJan 1, 2024 · If the post-cat sensor reacts in sync with the pre-cat sensor, the ECM knows that the oxygen storage capacity of the converter is low, and will record the fault. Another …
WebApr 5, 2024 · If you spend $900 or more to replace the catalytic converter, you may discover the check engine light coming on again later. Some mechanics will tell you to try replacing the oxygen sensors first, to see if that solves the problem. There are two of them, one before and one after the catalytic converter. WebOct 1, 1996 · The technique was used to measure the oxygen storage capacity of a fresh catalytic converter at inlet temperatures of 400, 500, and 600°C for catalyst volumes of 1.5L and 2.8L. The procedure was repeated after the converter had been aged at an inlet temperature of 800°C for 20, 40, and 60 hours.
