Abstract

This paper describes the quasi-dimensional numerical model for direct injection diesel engine, implemented in previously developed 0D model. The presented model uses a direct solution of equations for cylinder pressure and zone temperatures. A process of control volumes agglomeration from a set of the small fuel spray packages (control volumes) into one of the large ones is presented in details. This process contributes to fast simulation performances and to the numerical code stability. Numerical model validation was performed in three randomly selected engine operating points. Presented model results show a wide range of operating parameters which can be traced in detail, during the whole engine working process. Direct solution of temperature and pressure changes, in conjunction with the fuel spray packages agglomeration, presents a contribution to the quasi-dimensional engine process modeling.
