WebJune 5, 2024 by Sam Car Care Most engines minutely alter the fuel trim to replenish the oxygen in the converter and to add fuel for reduction. This helps to keep the converter at the correct temperature for the most efficient operation. If an engine is running too rich, it cannot store oxygen. WebAug 7, 2014 · To check a catalytic converter’s efficiency, two oxygen sensors are required — one upstream from the converter and one downstream. This way, oxygen storage can be …
WebThis test will show us the catalytic converter's ability to store and release oxygen within the cerium. If it fails this test it could be a good indicator that the catalytic converter is weak … WebDec 9, 2024 · 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.
