Performing the rich spike is determined to be unnecessary during a reducing state period from the time the rich spike ends to the time a preset time period has elapsed, and is also determined to be unnecessary when a change tendency of the detected output is determined to be an output decreasing state where the detected output is decreasing. The execution timing of the rich spike is determined using the detected output when the change tendency is determined to be an output staying/increasing state where the detected output is staying at a constant value or increasing after the end timing of the reducing state period. | 2017-05-18 |
20170138285 | METHODS TO ADAPT AIR-FUEL (A/F) CONTROLS FOR CATALYST AGING - A system includes an exhaust treatment system configured to treat emissions from a combustion engine via a catalyst. The system includes a controller configured to obtain an operating parameter indicating catalyst performance. The controller is configured to determine a deterioration factor indicating deterioration of the catalyst based at least in part on the operating parameter. The controller is configured to determine an adaptation term configured to modify an air-fuel ratio command for the combustion engine to account for the deterioration. | 2017-05-18 |
