Evolution and application of a pseudo-multi-zone model for the prediction of NOx emissions from large-scale diesel engines at various operating conditions

As revealed form the specific application, the proposed model captures qualitatively and after calibration quantitatively NOx variation with engine operating conditions and start of injection, which is very important for large-scale diesel engines. 75% and 98% of the test cases examined present a relative error less than 10% and 30% respectively. This encourages model's use for engine development and real-time NOx prediction.
