ABSTRACT:
A method for heating fuel injectors of an internal combustion engine supplies current from a power source to a plurality of electrically operable mechanical actuators. The current is supplied sequentially to at least two electrically operable mechanical actuators at a level sufficient to produce a time-varying magnetic field having a power density that substantially raises an armature temperature of said valve, while substantially maintaining the operating states that said at least two electrically operable mechanical actuators assumed prior to applying said current.
