Abstract
A spark coil control device for an internal combustion engine with several cylinders, including a target with a given number of protrusions distributed regularly around its periphery which is rotating with the crankshaft, at least one fixed-position primary element associated with the target, an ignition coil, a rotating spark distributor for inducing explosions within the various cylinders of the engine is succession by the intermediary of the associated sparkplugs, a stage for processing of the data signal retrieved by the position primary element which inter alia provides a synchronization signal and a speed of rotation signal, an electronic ignition advance calculator which at a first output provides a gross numerical value for ignition advance angle and, at a second output, a gross numerical value for the angle of conduction of the coil, and a power stage for commanding the ignition coil. The device further includes a command signal generator connected between the two outputs of the electronic advance calculator and the power stage commanding the ignition coil, wherein the processing stage for the primary element data signal engenders a third signal whose frequency is the prod…
