  • Determination of a solenoid injector coil temperature
    Patent number: 12180872
    Abstract: Disclosed is a method for determining a temperature of a solenoid injector including a coil and a needle when the solenoid injector is in a non-injection phase, the method being characterized in that it includes the following steps: powering the solenoid injector coil using an electric generator for a period of time tvoltage strictly shorter than a period of time tlim corresponding to a time for which the coil is under power causing the needle to open; measuring at least one value icoil of the current of the solenoid injector coil using a current measurement sensor when the coil is powered; and determining a temperature of the solenoid injector from the at least one value icoil of the current of the solenoid injector coil.
