摘要:Abstract Modelling and control of the injection process in common rail Diesel engines has attracted the interest of many researches also in recent years. This paper adds a new contribution for accurately modelling electro-injectors. Namely, not only nonlinear dynamics of the fuel flow and electro-mechanical aspects are considered but also a different representation of high-pressure wave propagation in pipes that feed the injector volumes. Model parameters are optimized by an evolutionary technique and a simulation study analyzes the prediction capability of the optimized model. The optimized model shows a superior fitting to experimental data than a nominal and a conventional model, and then it could be profitably used for injection control.
