► A NOx predictive model oriented to control applications has been proposed. ► In-cylinder pressure has been used as a basic input signal for NOx prediction. ► The model proposed combines a fast physical-based model with empirical look-up tables. ► The model considers NOx formation and NOx reduction phenomena. ► The model total calculation time is smaller than an engine cycle
