ABSTRACT:
The warm-up time of a glow plug starting device in a diesel engine is reduced by using as the material for the heat generating element in the glow plug a metallic resistance material whose resistance up to the starting temperature is less than two-thirds of the rated resistance of a conventional element. The starter circuit includes a detecting resistor in series with the heating element and a divider which divides the voltage across the heating element by the voltage across the detecting resistor in order to accurately determine the resistance and, thus, the temperature, of the heating element. The current to the element is interrupted and a self-holding starting relay is energized when the starting temperature has been obtained.
