ABSTRACT:
A diesel engine glow plug controlling device provided with a computer capable of processing digital values obtained through the analog-to-digital conversion of a temperature-equivalent voltage corresponding to the temperature of the glow plugs and a water temperature detection signal corresponding to the temperature of the cooling water of the diesel engine. The computer processes the digital values to decide the duration of closing of a glow relay provided in a power supply circuit for supplying a current to the glow plugs. When the temperature of the glow plugs is higher than a predetermined temperature, the computer decides a current supply period in which a detection current is supplied from detection current supply means to the glow plugs.
