Abstract:
This paper explores the use of rate of injection (ROI) and rate of momentum (ROM) to characterize the internal flow of an ECN gasoline direct injector. Rate of momentum has been successfully used in diesel injectors with this objective and for the first time, the measurements have been made on a GDi injector. The paper focuses on the experimental setup used and the different uncertainties and difficulties to translate the typically measured diesel technique to a gasoline injector.
