Fuel injection device for an internal combustion engine, comprising a magneto armature made of cobalt and iron
The fuel injection apparatus has at least one solenoid valve ( 50 ) for controlling the fuel injection. The solenoid valve ( 50 ) is triggered by an electrical control unit ( 52 ) and has a magnetic coil ( 88 ) and a movable magnetic armature ( 88 ). The magnetic armature ( 80 ) can move a valve ele...

| Zusammenfassung: | The fuel injection apparatus has at least one solenoid valve (
50
) for controlling the fuel injection. The solenoid valve (
50
) is triggered by an electrical control unit (
52
) and has a magnetic coil (
88
) and a movable magnetic armature (
88
). The magnetic armature (
80
) can move a valve element (
56
) between at least two positions. The magnetic armature (
88
) is at least essentially comprised of an alloy, which at least contains iron and cobalt, wherein the cobalt content is between 10% and 50%. The control unit (
52
) evaluates the chronological progression of the current conduction through the magnetic coil (
88
) and based on it, determines the time of a switching state of the solenoid valve (
50
) at which a fuel injection begins. |
