Abstract (en)
Compression ignition engine starting system includes one or more fast acting non-self-limiting electrically powered glow plugs (10) for fast cylinder warm up and actuating means including a current sensor (14) responsive to the level of curent consumed by the plugs (which level is a function of their temperature), a comparator (18) determining whether the current exceeds a predetermined level and, if it does, bringing into operation a timer (20) which passes current to the plugs for successive spaced limited periods only while they are above a given temperature to avoid overheating them.
