摘要：
A method for controlling an internal combustion engine includes monitoring engine operation including a parameter descriptive of NOx generation within the engine, determining a fast transient NOx estimate with a dynamic model based upon the monitored engine operation, and during a fast transient engine operation including an increase in an operating state of the engine and a substantial closing of an exhaust gas recirculation valve, controlling an engine system based upon the fast transient NOx estimate.
