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.

System and method for reducing power consumption when heating a fuel injector

A method to improve the performance of an electrically operable mechanical valve actuator is described. The system is capable of providing heat to targeted areas of an actuator so that valve performance may be improved during at least some operating conditions.

Method for improving operation of an electrically operable mechanical valve

A system and method to reduce the instantaneous power consumption during heating of a fuel injector is described. The system is capable of heating the fuel injectors of an engine at different times.

An internal combustion engine system having an internal combustion engine, a fuel source, a fuel filter for filtering fuel from the source to the engine, and a fuel pressure switch disposed between the fuel filter and the fuel source. An additional sensor is provided for sensing a condition of a substance fed to the engine. An output device is connected to both the fuel pressure switch and the additional sensor for indicating when either the fuel pressure switch indicates an improper fuel pressure condition or the additional sensor indicates the sensed condition is an unwanted condition.
