| Zusammenfassung: | Disclosed is a method of controlling a fuel injector 20 of an internal combustion engine 10 during a fuel injection cycle comprising: powering the fuel injector using pulse width modulation at a first switching frequency during a first phase of the fuel injection cycle; powering the fuel injector using pulse width modulation at a second switching frequency that is different to the first switching frequency during a second phase of the fuel injection cycle and powering the fuel injector using pulse width modulation at a third switching frequency during a third phase of the fuel injection cycle. Also disclosed is a fuel injection apparatus for an internal combustion engine. |
