    摘要： The present invention prevents the occurrence of damage on a small diameter portion 4a which is formed on a rear end portion of a ceramic heater fixed in a metallic outer sleeve 8. The ceramic heater 4 is fixed in the metallic outer sleeve 8 by blazing or the like in a state that a heat generating portion formed on a distal end thereof is exposed to the outside. The rear end portion of the ceramic heater 4 is positioned inside the metallic outer sleeve 8, and the small diameter portion 4b is formed on the rear end. The rear-end small diameter portion 4b of the ceramic heater 4 is connected to an electrode lead-out member (electrode lead-out wire 10) for taking out a positive electrode of a heat generating material. Granulated powder (alumina, for example) 18 made of inorganic insulating material is filled in around a connecting portion of the ceramic heater 4 in the metallic outer tube 8 and the electrode lead-out-wire 10, and in addition, magnesia 20 is sealed outside the granulated powder. Thereafter, swaging is performed to bring the magnesia 20 into a highly dense state thus fixing the electrode lead-out wire 10 and an electrode lead-out rod 12 in the metallic outer sleeve 8.

    摘要： To suppress deterioration caused by thermal stress without sacrificing the required maximum temperature.At a time when post glow of ceramic glow plugs 50-1 to 50-n ends, when it has been determined that a cooling state inside a combustion chamber of an engine is not in a predetermined strong cooling state for a first predetermined amount of time or longer, post glow energization is stopped (S106, S112), but when it has been determined that the cooling state inside the combustion chamber of the engine is in the predetermined strong cooling state for the first predetermined amount of time or longer, a preset post glow extension voltage-use map is used to obtain a voltage when extending post glow energization, and post glow energization extension is started using that voltage, and thereafter, when it has been determined that the cooling state inside the combustion chamber of the engine is transitioning from the predetermined strong cooling state to an abated state for a second predetermined amount of time or longer, post glow energization extension is stopped (S108, S110), to thereby alleviate thermal stress and suppress ceramic heater deterioration.
