Summary: | The present invention relates to cylinder imbalance correction system and method, in particular to the systems and methods for determining and correcting air/fuel imbalance between cylinders of an internal combustion engine. The method includes determining and implementing a deactivation policy; evaluating whether the engine is operated in the presence of the air/fuel imbalance between the cylinders; when an imbalance is identified, implementing an alternative deactivation strategy; based on a result of the alternative deactivation strategy, identifying a source cylinder of air/fuel imbalance, and correcting the fuel flow to the source cylinder.
本发明涉及气缸不平衡校正系统和方法。具体地,提供了用于确定和校正内燃发动机的气缸之间的空气/燃料不平衡的系统和方法。确定并实施停用策略。评估发动机是否在气缸之间存在空气/燃料不平衡的情况下操作。当识别到不平衡时,将实施替代停用策略。基于替代停用策略的结果,识别空气/燃料不平衡的源气缸,并校正至该源气缸的燃料流量。 |
