Abstract
PURPOSE: To maintain a steady temperature at glow plugs against power supply voltage variations, by controlling the electric supply to the glow plugs automatically.
CONSTITUTION: A preheating control device is provided with glow plugs 3W6 constructed of resistance heaters, a steady preheating resistance 7, a steady preheating resistance 8 with a lower resistance value than the resistance 7, a relay 9 which selects an electric supply route passing through the resistance 7, a relay 10 which selects an electric supply route passing through the resistance 8, and a relay 11 which selects an electric supply route which bypasses resistances 7 and 8. A control circuit which controls these relays 9W11 are constructed of a comparator circuit 15 and a distribution circuit 27. The control circuit selects the route of electric supply by controlling relays 9W11 for setting the voltage assigned to glow plugs 3W6 near to a rated voltage in order to maintain the temperature of glow plugs at a steady level.
