Abstract
A control apparatus for glow plugs provided for a diesel engine is disclosed, in which the time for preheating of glow plugs prior to starting of the engine, that is, the time for applying an electric current to the glow plugs from a battery, is controlled according to such factors as engine temperature and battery voltage. When the engine is cold, control is carried out so that as the engine temperature is lower or the battery voltage is lower, the preheating time is more prolonged. Accordingly, an optimum preheating time is ensured. When the engine is warmed up, control is carried out so that even is a key switch is set at a preheating position, preheating is not effected whatsoever.
