Control apparatus and method for internal combustion engine cylinder balance

A method of operating an internal combustion engine of a vehicle is provided to maintain cylinder balance. A first operating mode corresponding to a steady state operation of the internal combustion engine is differentiated from a second operating mode corresponding to a transient operation of the internal combustion engine based upon a first operating parameter of the internal combustion engine.In the first operating mode, a first control strategy provides cylinder balance. In the second operating mode, a second control strategy, different than the first control strategy, provides cylinder balance. The second control strategy utilizes a dynamic factor based upon a second operating parameter of the internal combustion engine. 提供了一种操作车辆的内燃机以维持气缸平衡的方法。基于内燃机的第一操作参数将对应于内燃机的稳态操作的第一操作模式与对应于内燃机的瞬态操作的第二操作模式区分开。在第一操作模式中，第一控制策略提供气缸平衡。在第二操作模式中，与第一控制策略不同的第二控制策略提供气缸平衡。第二控制策略利用基于内燃机的第二操作参数的动态因子。
