Abstract (en)
[origin: EP0618360A1] This device for detecting an operating defect in an electronic ignition system of an engine, especially for a motor vehicle, of the type including a computer for control of the supply to primary circuits of ignition coils (1, 2, 3), the secondary circuits of which are linked to spark plugs associated with the cylinders of the engine, is characterised in that it includes means (7, 8, 9) for statistical analysis of the durations of sparks between the electrodes of the spark plugs, in order to determine an operating defect. <IMAGE>
