A fuel injector includes a magnetic coil whose power dissipation is utilized to pre-heat fuel flowing through the fuel injector. The magnetic coil is arranged so that a thermal coupling between the magnetic coil and the fuel flowing through a heat exchanger segment is acquired. In addition, a Peltier element (which functions as a heat pump) can be arranged between the magnetic coil and the heat exchanger segment. Furthermore, the fuel can also be heated using a heating coil.
