Abstract
PURPOSE: To control the preheat time of a plug through the voltage drop of a current supply wire leading to the glow plug of a diesel engine by detecting the potential difference between the ends of the wire with the use of a detecting circuit.
CONSTITUTION: A battery 1 is connected partly with a key switch 3 through a wire 2 and partly with respective glow plugs 6 to 9 through s switch contact 4 and a current supply wire 5. There is connected between the both terminals of the wire a current detecting circuit A which is operative to detect the potential difference. The resultant signals are fed through a bistable circuit C having an indicating lamp 12 to a drive circuit D, which is also connected with such a voltage detecting circuit B as in turn is connected with the start contact of the key switch 3. The voltage drop in the supply wire is connected by means of the two circuits A and B so that the contact 4 is rendered conductive by the coil 11 of the circuit D, when the drop is lower than a preset level, thereby to preheat the plugs 6 to 9
