| description | Disclosed is a method of operating a fuel injector 160 of an internal combustion engine 110. The method comprises supplying a first energizing electrical current 510 to an injector solenoid 161, causing the opening of an injector control volume CV and a pressure reduction insaid injector control volume CV, for a first energizing time ET1, which is predetermined to avoid that the pressure in the injector control volume CV approximates a value which would cause an injector needle 163 to raise up and a fuel injection to start. After a predetermined time interval DT a second energizing electrical current 520 is supplied to the injector solenoid 161, for a predetermined second energizing time ET2, which is a function of a rail pressure (prail) and a fuel injection quantity (Q). |
