The paper presents a brief of mathematical model describing a two-zone, quasi-dimensional combustion in Diesel engine chamber. In order to simulate NOX emission, the simplified Zeldovitch mechanism was applied in nitric oxide formation model. An outline of the model can also be applied for engines of other types, where stratified charge is formed, e.g. in GDI spark ignition engines. In case of Diesel engines with direct fuel injection, the model includes injection sub-model that allows investigation of injection rate effect on NOX emission. This important advantage may be very useful for pre-fixing injection strategy in Common-Rail systems prior test bed fine research.
