Ignition system including a measurement device for providing measurement signals to a combustion engine's control system
Abstract:
The present invention relates to an ignition system (T) for a combustion engine, the internal combustion engine comprising a control system, the ignition system (T) further comprising a power source (30), at least one ignition coil (10, 11, 12) having at least one primary coil (L2, L4, L6) and one secondary coil (L3, L5, L7) for a spark plug (13, 14, 15) and a measurement device (50) for at least one of the parameters spark current, ion current, ignition voltage and primary voltage, said measurement device (50) being adapted to provide measurement signals to said control system for regulating the ignition system (T), the ignition system (T) also comprising means for transforming up voltage and storing energy, and a plurality of switches (S1-S7), said control system being adapted to control said switches (S1-S7), by means of said measuring signal(s), for the supply of adaptive spark energy and/or to control the polarity of the spark.
Abstract(Chinese):
