Claims

[Claims for Utility Model Registration] An energizing circuit that applies a constant voltage of 1 to the glow plug through a switching element, and a timer that is set for one hour in advance based on the temperature characteristics of the glow plug and is set at the starting position of the 4-switch. A timer circuit operates to close the switching element, and a predetermined νON/OFF time is set based on the temperature rising and cooling characteristics of the plug, and the timer circuit operates when the σ timer expires for one hour. A preheating time control device for a glow plug, further comprising a trigger circuit for opening and closing the switching element.
