Injector

An internal combustion engine having an injector for injecting fuel, wherein the injector comprises:

• an injector housing;
• a movable nozzle needle that is arranged in the injector housing and has a nozzle needle tip;
• and
• a nozzle needle seat for receiving the nozzle needle tip, wherein
• a contact pairing of the nozzle needle and the nozzle needle seat forms a switch that adopts a closed state on a contact of the nozzle needle tip with the nozzle needle seat and an open state on an interruption of the contact;
• the injector has an input line and an output line connected to an actuator, the actuator controlling movement of the nozzle needle;
• a ground connection comprising the switch, a first connector connected to the input line, and a second connector connected to a ground through the injector housing, and the ground connection reducing current in the output line when the switch is closed;
• and
• a resistor is connected between the first connector of the switch and the input line,
• wherein the resistor is a high temperature resistor chip.
