PURPOSE:To keep the heating temperature of each glow plug constant, by connecting each glow plug for carburetion and ignition of fuel to a power source in parallel when each heating temperature is less than the specified value but in series when it is more than the specified value, respectively. CONSTITUTION:Immediately after a start switch 12 is turned on, since each of glow plugs 14 and 15 for carburetion and ignition of fuel are not reached to the specified temperature, selector switchs 14 and 15 are turned on by a controller 17, and a selector switch 18 is turned off, respectively. With this control, each of these glow plugs 7 and 8 is connected to a power source 11 in parallel via each of resistors 16 and 13, whereby these glow plugs 7 and 8 are speedily heated. On the other hand, if these glow plugs 7 and 8 are reached to the specified temperature, these selector switches 14 and 15n are controlled to be turned off and the selector switch 18 to be turned on, respectively, by the controller 17, thus a circuit is selected to being in series. |
