A New Phenomenological Approach to Simulate the Injection Rate of a Diesel Solenoid Valve Injector

This paper presents a phenomenological and semi-empirical simulation model to predict the injection rate of a diesel solenoid valve injector based on few injection-quantity measurements and indications (EMI). The approached injection rate will be used as the input data for a subsequent model which simulates the rate of heat release (ROHR). The injection rate model encompasses algebraic relations and differential equations deviated of the equations of motion and conservation, which describe in modular sub models the characteristic processes in the injector. The process and its assumptions are explained step by step for each sub model. Additionally the injection rate predictions are presented and compared with experimental results for a selected reference solenoid valve injector.     «
