ELECTROMAGNETIC FUEL INJECTOR WITH TWO INDEPENDENT COILS AND RELATED CONTROL METHOD

An electromagnetic fuel injector (1) having: a tubular support body (4); an injection nozzle (3) arranged at an end of the support body (4); an injection valve (7) coupled to the injection nozzle (3); a plunger (8), which is movable, so as to adjust the fuel flow through the injection nozzle (3), between a closed position and an open position of the injection valve (7); an electromagnetic actuator (6) provided with a main electromagnet (11) configured, when it is activated, to apply a force to the plunger (8), which pushes the plunger (8) towards the open position of the injection valve (7) and with a secondary electromagnet (12) configured, when it is activated, to apply a force to the plunger (8), which pushes the plunger (8) towards the closed position of the injection valve (7); and a closing spring (10) configured to push the plunger (8) towards the closed position of the injection valve (7).
