Abstract:
A method for predicting a NOx amount, may include determining a reference NOx amount according to a driving condition of an engine, primarily correcting the reference NOx amount according to an exhaust gas recirculation (EGR) ratio, and secondarily correcting the primarily corrected NOx amount according to an environmental factor and the driving condition.
