Individual cylinder fuel control systems and methods for oxygen sensor degradation |
摘要 |
A system includes an offset determination module and a correction determination module. The offset determination module determines an offset value based on an average response time of an exhaust gas oxygen (EGO) sensor located upstream of a catalyst in an exhaust system. The offset value relates one of a predetermined number of cylinder imbalance values to a cylinder of an engine. The correction determination module determines a fueling correction for the cylinder based on the offset value and one of the predetermined number of cylinder imbalance values. |
