To suppress current fluctuations upon commencement of driving and prolong lifespan by reducing electric stress caused by current fluctuations. A glow plug 1, a glow switch 2, and a stabilizing coil 3 are series-connected, and upon commencement of the drivi...

There is provided a control device for a glow plug, capable of controlling the energization of a resistance heater of the glow plug by a resistance control process while attaining good resistance control response under cooling of the heater by fuel injecti...

The method involves generating an effective voltage from a system voltage by pulse width modulation. The effective voltage is applied at a glow plug, and is changed as a function of one or more engine parameters. A nominal value of the effective voltage is...

The PWM based operating method involves measuring a voltage present at a heating element (R) e.g. glow plug and/or a current flowing through the heating element at specified intervals during a voltage pulse application. Measured values or corresponding val...

A glow plug energization control apparatus includes a unit for performing an energization control so that a sheath heater is quickly heated when a key switch is put in an on position, a unit for performing, subsequently to this, an energization control to ...

The glow plug control method has the vehicle on-board voltage used by a control device (16) for providing a required pre-glow voltage, with determination of the difference between the actual and the required pre-glow voltages when the required pre-glow vol...
