Abstract
This paper is devoted to modelling of the fuel spray propagation into a cylinder of direct injecting internal combustion engines. A number of experiments were carried out to obtain data for the calculation of velocity profiles inside the spray, as well as its trajectory under cross-flow conditions. A one-hole injector was used in the experiments. The injection pressure varied from 100 till 150 bar and the air cross-flow velocities ranged from 0 till 50 m/s. The semi-empirical model was developed to describe the fuel spray propagation. The results obtained from the model and experiments were compared. The agreement of the results from experiments and the model for low velocities of the cross-flow (0-25 m/s) is significant. However, for high velocities of the cross-flow (30-50 m/s) the agreement is low. Thus, in this paper the improved model of the fuel spray propagation is proposed. A new model is based on splitting spray into parts with different densities. Each part moves with its own velocity and along its own trajectory.
