Imbalance re-synchronization control systems and methods

摘要: Fueling to one cylinder of an engine is selectively adjusted based on a correction associated with the cylinder. An instability module increments counter value when equal first predetermined and second was previously other values. The generates indicator value. A variance imbalance values can be determined samples exhaust gas oxygen signal. Two variances are determined: adjustment correction, without correction. checking variances. re-synchronization re-synchronizes cylinders, respectively, in response generation and/or indicator.
