Abstract

See full text

Methods are provided for estimating the NOx content 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 NOx model. The global NOx model may be derived using a plurality of steady state data points relating to local NOx emission models. The steady state data points may be derived using a plurality of set and variable operating parameters. The global NOx model allows for prediction of the engine-out NOx content of exhaust gas in real time and without a NOx sensor, even if engine operating parameters change.
