Abstract
A mathematical model describing heat release and pollutant formation in direct injection diesel engines has been developed and tested. The model includes several empirical constants which can be tuned to fit the requirements of a particular engine. Sensitivity studies indicate that the model is most responsive to those constants which control fuel/air mixing. Numerical experiments strongly suggest that diffusion flames modelled by spherical droplet flames are unsuitable for this type of system. The model has been tested against results obtained with a single cylinder diesel engine. Reasonable predictions of the influence of engine design and operation parameters on NOx emissions were obtained. However, predictions of smoke emissions were not satisfactory.
