An investigation into the effects of diesel fuel properties on the injection characteristics of a common rail injection system

This study set out to investigate the effects of diesel fuel properties on the behaviour of a common rail fuel injection system, with particular emphasis on the injection rate shape characteristics. The investigation included the design and commissioning of experimental equipment for the measurement of fuel properties at typical common rail pressures, as well as the measurement of instantaneous fuel flow rate by a modified Bosch Indicator method. Data was then collected for two different diesel fuels, operating in two different fuel injector designs. The two fuels were EN590 (a European reference fuel) and GTL (a fuel derived from natural gas). The two injectors were a Bosch solenoid type injector, and a Bosch piezo type injector.
