Abstract
Methods are provided for estimating the NOcontent of exhaust gas produced by an internal combustion engine. The method includes determining one or more operating parameters. The method further includes applying the determined operating parameter(s) to a global NOmodel. The global NOmodel may be derived using a plurality of steady state data points relating to local NOemission models. The steady state data points may be derived using a plurality of set and variable operating parameters. The global NOmodel allows for prediction of the engine-out NOcontent of exhaust gas in real time and without a NOsensor, even if engine operating parameters change.
