In order to conduct the three-dimensional numerical analysis of the mixture formation and combustion processes in diesel engines, submodels for fuel sprays, ignition and combustion had been investigated. In this paper, the Livengood-Wu's model or the Schreiber's reduced kinetic model was applied as an ignition model. As a combustion model, the Reitz's model was employed. These submodels were incorporated into the author's GTT code, and the combustion process in a direct-injection diesel engine and that in a premixed compression ignition engine were numerically analyzed using this code. The validity of the submodels was confirmed by comparing the calculated results with the experimental ones.
