摘要： An electric current supply control apparatus for a glow plug, and glow plug and the electric current supply control apparatus connected to the glow plug. In a transition state in which the load acting on an engine increases such as at the time of acceleration (S14: YES), an instruction signal which instructs increasing of an EGR amount is transmitted to an ECU (S18). Further, electric current is supplied to a heat generation resistor of a glow plug through resistance PI control (S20), whereby the temperature of the heat generation resistor is stably maintained at a target temperature, and stability of combustion is enhanced. Thus, even at the time of acceleration, generation of NOX can be suppressed effectively by increasing the EGR amount without lowering the engine output.

摘要： A joint structure which does not exhibit impaired joining strength induced by exposure to heat cycles and the occurrence of migration, in a ceramic heater for a glow plug or like device. A heating element 6 is embedded in a silicon nitride ceramic substrate 5. Lead wires 15 are joined to corresponding lead wire connection terminals 11, which are connected to the heating element 6 while electrical continuity is established therebetween, by use of a brazing metal 20 which contains a predominant amount of copper. The brazing metal 20 used for joining assumes the form of a brazing metal layer having a thickness of 30-400 &mgr;m.

摘要： To provide a ceramic heater which is better in the durability of an ion current detecting electrode portion and which can be manufactured at a low cost. A ceramic heater 1 is provided with: an insulating ceramic substrate 13; a resistance heating element 10 buried in the insulating ceramic substrate; and an ion current detecting electrode portion 14 formed integrally with the resistance heating element in the insulating ceramic substrate and having its own surface portion exposed as an ion current detecting face to the surface of the insulating ceramic substrate. The ion current detecting electrode portion 14 is constructed, at its portion including at least a portion of the ion current detecting face 15, of a conductive ceramic phase which is composed mainly of non-metallic conductive ceramic having a cation component made of a nonmetallic element, such as silicon carbide.
