  • Patent number: 7487753
    Abstract: There is provided an energization control apparatus for a glow plug in an engine, including a post-start glow section to control energization of a resistance heater of the glow plug by a battery after start of the engine. The post-start glow section is configured to evaluate revolution stability of the engine and control the energization of the resistance heater according to a first control pattern when the engine revolution stability is higher than or equal to a threshold level and according to a second control pattern that achieves a higher temperature of the sheath heater than the first control pattern when the engine revolution stability is lower than the threshold level.
