Abstract

PURPOSE: To keep the temperature of glow plugs at a constant level by controlling the quantity of electric supply to the glow plugs by means of a signal generation circuit which generates an output at a certain voltage drop on both ends of a detection resistance and a delay circuit which generates an output after a lapse of delay time corresponding to the power supply voltage.
CONSTITUTION: A preheating control device is composed of glow plugs 8W11 constructed of heaters with a fixed resistance temperature coefficient, a temperature control relay 3 which makes a change-over between the first electric communication state to supply electricity to glow plugs 8W11 via a steady preheating resistance 5 and the second electric communication state to supply electricity as short-circuiting the steady preheating resistance 5, a detection resistance 7 on the way of the electric supply to glow plugs 8W11, a comparator 6 which issues an output signal when a certain voltage drop occurs on both ends of the detection resistance 7, and a delay circuit 12 which issues an output signal after a lapse of delay time determined in accordance with the power supply voltage on the basis of the above-said output signal. Consequently, two sorts of electric communication states can be changed over mutually at a period corresponding to the power supply voltage, and the temperature of glow plugs is maintained at a fixed level.
