装置。 A diesel engine control device configured to perform preheating control of a glow plug includes an output port that enters a high impedance state when the drive voltage becomes inoperable due to a drop in the drive voltage, and the glow plug is heated from the output port. a microprocessor that outputs a control signal for preheating control; a means for outputting a starting signal indicating that the diesel engine is in a starting state; a relay means for turning on and off energization to the glow plug; In response to the signal and the starting signal, when the output port is in a high impedance state and the diesel engine is in a running state, the glow plug is energized regardless of the control signal, and the diesel engine is in a starting state. A control device for a diesel engine, comprising: a control circuit that provides a relay drive signal to the relay means for energizing the glow plug in accordance with the control signal when the glow plug is not available.
