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 (S 14: 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 NO x can be suppressed effectively by increasing the EGR amount without lowering the engine output.

摘要： A heating device (1) has a heating element (10) capable of generating heat energy when receiving an electric power, and a power supply control module (20) for performing a power supply so that a plug resistance value R GP of the heating element becomes equal to a target resistance value R TRG . The heating element and the electric power supply control module are accommodated together in a housing casing (30) of a cylinder-like shape. The power supply control device (20) has a reference resistance value storage means (231) for storing a resistance value of the heating device, as a reference resistance value R C , at a predetermined target temperature T TRG , a resistance value change reflecting means (233) and a deterioration judgment means (234). The resistance value change reflecting means (233) allows the power supply to the heating element (10) when the plug resistance value R GP of the heating element (10) is lower than the reference resistance value R C during the power supply to the heating element (10), and halts the power supply to the heating element (10) when the plug resistance value R GP of the heating element (10) exceeds the reference resistance value R C during the power supply to the heating element (10) in order to reflect, to the power supply control, the resistance value change due to the temperature change of the heating element (10). The deterioration judgment means (234) judges whether or not the heating element (10) is deteriorated by using a deterioration power value P WRN in a deterioration state, as a power threshold value P REF , calculated by multiplying an initial reference power value P INT with a predetermined rate.

摘要： The accuracy in controlling the heating temperature of a glow plug and the reliability of the control operation are improved.
An electronic control unit 101 is configured such that a standard applied voltage for glow plugs 50-1 to 50-n is set according to the engine speed and the load conditions of the engine. In addition, a correction coefficient set in advance according to the temperature classification of the mounted glow plugs 50-1 to 50-n is readably stored in the electronic control unit 101 as a correction coefficient map. By multiplying the standard applied voltage by a correction coefficient K read from the correction coefficient map and applying a voltage of the multiplication result to the glow plugs 50-1 to 50-n as a driving voltage through the power circuit 102 to perform driving control, stable and reliable heating temperature control can be realized regardless of variations in the heating temperature characteristics.
