<p>In one aspect of the present invention, an apparatus for controlling the temperature of a plurality of glow plugs of a multi-cylinder internal combustion engine is disclosed. A voltage sensor (130) produces a signal relative to the magnitude of the sensed voltage across a glow plug. A microprocessor (150) compares the magnitude of the sensed signal with a preselected magnitude indicative of a predetermined temperature glow plug and responsively produces a current command signal. An alternator (115) receives the current command signal and responsively delivers alternating current to the glow plugs.</p> |
