Abstract
A fuel injector assembly for an internal combustion engine including an injector body in fluid communication with a source of fuel and a nozzle assembly through which the fuel is dispersed from the fuel injector assembly during an injection event. A high pressure fuel delivery system provides high pressure fuel to the nozzle assembly. In addition, the fuel injector assembly includes a combined initial injection and peak injection pressure regulator which is operable to control the nozzle assembly to regulate the rate of fuel injection at the beginning of an injection event and is further operable to limit the maximum pressure of the fuel dispersed from the nozzle assembly.
