Abstract

PURPOSE: To prevent the useless power consumption and improve durability of a glow plug by controlling the glow temperature of the plug in accordance with the temperatures of the plug and the engine.
CONSTITUTION: When a switch S is closed to start a diesel engine, a relay operates to close a contact 6a. A glow plug 1 has a small resistance value at low temperatures. A comparator 5 generates high level output, the relay 6 closes its contact 6a, and the temperature of the plug 1 is raised on power supply. As the temperature of the plug 1 rises, the output of the comparator 5 comes down to a low level so that the power supply and temperature rise of the plug 1 stop. Whether of not the plug 1 is supplied with power depends on whether the poing P voltage whose change is made in accordance with that of the resistance value of the plug 1 is higher or lower than the point Q voltage whose change is made in accordance with the resistance value of a water temperature sensor 3.
