Abstract:
Systems and methods of estimating a fluid injector tip temperature. A controller having a processor and a memory supplies a current to a coil of a fluid injector, a resistance of the coil is measured when the current is supplied to the coil, a coil temperature is determined based on the measured resistance, and a tip temperature of a fluid injector tip is estimated based on the determined coil temperature.
