摘要
The system has a first end (P1) of the primary winding connected to a voltage source (BAT) and its other end (P2) connected to earth via a switch component (SP). The one end (S1) of the secondary winding is connected to a central electrode (E1) on a spark plug and its other end (S2) is connected to earth via at least one capacitor (C1). The capacitor is charged by the spark current (Is) produced in the secondary winding up to a predetermined voltage level given by a voltage-limiting component parallel coupled over the capacitor. A first ignition voltage is induced in the secondary winding after the switch component has broken a primary current (Ip) formed by the primary current and where a spark current (Is) is formed in the secondary winding circuit. The voltage limiting component comprises at least one zener diode has a breakthrough voltage between 600-2000 volts, preferably 1000 volts. The Zener diode limits the charging load by the spark current of the capacitor to a voltage level corresponding to the breakthrough voltage.
