Diesel OBD-II system for detection of degradation of catalyst activity |
摘要 |
A method of monitoring catalyst activity that includes injecting hydrocarbon into the engine exhaust flow sufficient to maintain a constant concentration of reductant into the catalyst under variable engine exhaust flow conditions thereby permitting an accurate calculation of the actual HC conversion by the catalyst, and a determination of whether the catalyst is currently meeting emission regulations.
