ABSTRACT:
A glow plug controlling apparatus for a diesel engine comprises a glow plug having a predetermined resistance-temperature characteristic which is mounted on the diesel engine and in which a rated value of voltage applied thereto is determined to be lower than a power source voltage, a quick preheating circuit comprising a first switch connected in series between said glow plug and a power source, a stable preheating circuit comprising a serial connection of a resistor and a second switch which is connected in parallel to the quick preheating circuit, a voltage detecting means for detecting a voltage applied to the glow plug when the second switch of the stable preheating circuit is closed, and a driving signal controlling means for determining a driving time to drive the second switch in response to an output from the voltage detecting means.
