Abstract:
1. An ignition system for an internal combustion engine having a combustion chamber and a fuel injection device which injects the fuel directly into the combustion chamber in stream-guided fashion with formation of a mixture cloud formed by an injection and required for combustion, wherein the ignition system is configured so that the ignition system has a positive polarity and generates ignition sparks after the positive polarity was established to impede a shift of the ignition sparks, wherein a spark plug is provided and includes an insulator, an electrically conductive middle conductor which protrudes past the insulator towards the combustion chamber and forms a middle electrode, and at least one rod-like ground conductor extending into the combustion chamber substantially parallel to the middle electrode and bent toward the middle electrode.
