Abstract
Variations in high pressure common rail (HPCR) system characteristic parameters influence injection characteristics and lead to fluctuation of fuel injection quantity (FIQ). The fuel injection quantity fluctuation (FIQF) has adverse affects both on coherence and stability of HPCR system. Numerical simulation model of HPCR has been developed and its accuracy has been validated by experimental results. Influence law and generation mechanism of FIQF caused by variations of different parameters such as fuel return pressure, solenoid reset force, control valve lift, fuel return orifice (A orifice) diameter, fuel inlet orifice (Z orifice) diameter, injector needle lift, needle pre-tightening force and injector flow coefficient in entire operating conditions have been analyzed.
