Development of a Dynamic Model for Studying the 1st Generation of Common Rail Injectors for HSDI Diesel Engines 2001-24-0013

The aim of this work is to investigate Common Rail injector behavior towards multiple injection strategies. A numerical model has been developed to simulate the electro-fluid-mechanic behavior of a Bosch mass production injector (standard injector) and validation against experiments has been performed. In order make the injector performing multiple injections, a deep investigation has been numerically carried out. The numerical study highlighted different area where injector may be improved with particular emphasis on electronic driving circuit. A new driving circuit concept, previously developed, has been successfully simulated showing promising fast-response capability for injector actuation.
