A computer model of diesel engine operation based on the interconnected calculation of diesel fuel spray and the processes in the combustion chamber is extended for the calculation of Nitrogen oxidizing. A number of chemical reactions with O2, O, N2, N, NO, OH, H, H2 are included in the model.

Numerical simulations of in-cilinder processes were performed in order to study influence of different source data for computer model of diesel engine operation. Calculations were fulfiled on different levels: air-fuel spray, thermodynamics processes in combustion chamber and engine output parameters. Comparision of calculated and experimental results on all levels allows selection of reasonable values of source data. So we can obtain parameters of spray and in-cylinder processes near to real ones.
