Abstract

A glow plug control apparatus and a glow plug control method using the same are provided. The glow plug has a housing having an axial hole, a heater member arranged in the axial hole and heated by a current conduction, and a seal member adapted to connect the heater member between the heater member and the housing in a relatively movable manner in the axial direction in the axial hole of the housing and in an elastic manner and prevent an entry of a combustion gas into the gap between the housing and the heater member. The glow plug control apparatus has deposit accumulation time current conduction means for conducting a current to the heater member so that the seal member is heated to higher than or equal to 200 degrees centigrade in a driving state where deposit is accumulated in the axial hole.
