摘要：

In this paper a mathematical model for numerical simulation of the fuel injection process in the electronically controlled high pressure ECD-U2 fuel injection system for a Diesel frock engine is presented. The proposed mathematical model is based on the assumption that the injection pressure of a selected engine operating regime is kept constant. Keeping this in mind, attention is focused on the processes in the injector: Several configurations of the injector are considered Consequently, it is possible to choose between two different types of solenoid valves, as well as between the return and the boot valve. The influence of different parameters on the injection characteristics is discussed briefly using the obtained numerical results. (C) 1999 Journal of Mechanical Engineering. All rights reserved.
