Authors Abstract
Content
A computational one-dimensional model of a solenoid operated common-rail ballistic injector has been performed and implemented in the AMESim software. A complete characterization of the different elements that comprise the system has been carried out in order to describe its behaviour. The model has been validated against mass flow rate experimental data along a wide range of engine-like operating conditions by varying the injection pressure, energizing time and injection temperature. The setup of the experimental facility is also described in the paper, with special attention to the injection temperature control. Results made it possible to quantify the influence of this injection temperature on the dynamic behaviour of such kind of injectors, where the needle lift is not limited and thus the viscous friction is deemed to be important on both the opening and closure stages of the injection event.
