ABSTRACT:
A distributor-less ignition system for an internal combustion engine, having a control unit and an ignition coil coupled to the control unit. The ignition coil has a primary coil switched by the control unit and a secondary coil that has a terminal. A plurality of spark plugs are electrically connected at one end of the secondary coil to the same terminal of the secondary coil. A controllable semiconductor switch is respectively electrically connected between the terminal and each of the spark plugs. The semiconductor switch for the spark plug to be triggered is switched at least approximately at the same time by the control unit as the primary coil.
