Artigo Completo:

Port fuel injection (PFI) engines play a key role in Brazil widely used as power source of the majority car passengers on the market. Selection criteria of fuel injectors used for PFI application is based on injector Dynamic Flow Range (DFR) which means ratio of the maximum to minimum dynamic flows, i.e., the usable minimum and maximum fuel flow. Evaluation of DFR relies usually on measurements on test benches using constructed samples. This paper presents the development process of 1D simulation model of fuel injector for PFI application built on AMESim® software. This functional model integrates magnetic, mechanical and hydraulic domains and it aims to assist selection and specification of proper fuel injector to fulfill application requirement establishing a better first-time product capability reducing samples construction. Results show a good correlation with real prototypes.
