ABSTRACT:
A circuit for controlling glow plug energization for use with a diesel engine having at least one glow plug energized by actuation of an ignition switch. The circuit has a simulator for producing a simulation signal indicative of glow plug temperature, a generator for generating a reference signal with a level which is determined in relation to a desired glow plug temperature and which is changed in magnitude in response to the change in the voltage of said voltage source and the temperature of the engine coolant, and a switch responsive to the result of comparing the simulation signal with the reference signal for controlling the flow of the current from said power source to the glow plug to energize the glow plug, whereby the glow plug is energized so as to be heated to said desired glow plug temperature.
