Title: Research the fuel injection characteristics of a common-rail solenoid injector
Keywords: solenoid injector, common-rail, simulation, experimental test, rate of injection
Abstract: In this study a solenoid common-rail injector was investigated in order to achieve the fuel injection characteristics. This injector is designed by Delphi to be used in 2.0liters diesel engine for light-duty vehicle application. Firstly, an injector simulation model was developed in advanced simulation code AVL BOOST Hydsim. The geometrical parameters were taken from technical documentation while the mass parameters were measured. Secondly, an experimental study of the injector was conducted on the injector’s test bench according Delphi test procedure at three injection pressures. The injector model was validated as simulated and measured injected delivery was compared at different injection duration. Finally, the rate of injection was estimated as a function of crank angle at different engine operating points as well as the influence of some geometric parameters on the injection process.
