Abstract :
Research on Common Rail (CR) injection systems has helped to increase the performance of Diesel engines in terms of available power and fuel consumption in compliance with the restrictions of noise and pollutant emissions. To accomplish these tasks, the last generation of electro-injectors is being developed to advance and improve structure and operation in achieving an accurate fuel metering. This paper presents a model of an electro-injector for common rail systems that is able to predict steady-state and transient behavior. Good results are obtained by simulation in different working conditions and match experimental data to a good extent.
