CA 2115007
Absolute engine position sensing is provided by monitoring the temporal relationship of energization of multiple spark plugs sharing a common source of drive energy in a direct ignition application. The spark plugs are connected across the source with opposing electrical polarity, and the relative time of discharge across the plugs compared by sensing the time and polarity of high speed transient activity in proximity to the source.
La détection de position absolue moteur est assurée grâce au contrôle du rapport temporel d'excitation de plusieurs bougies d'allumage qui partagent une source commune d'énergie de commande dans une application à allumage direct. Les bougies d'allumage sont reliées aux bornes de la source avec polarité électrique contraire, et le temps relatif de décharge aux bornes des bougies est comparé grâce à la détection du temps et de la polarité de l'activité transitoire à grande vitesse à proximité de la source.
