An ignition system for an internal combustion engine, having a combustion chamber and a fuel injection device which injects a fuel directly into the combustion chamber in stream-guided fashion, is configured so that the ignition system has a positive polarity.

Ignition system for an internal combustion engine

A fuel-injection system including a fuel injector, having a plurality of spray-discharge orifices, which meters fuel into a combustion chamber of an internal combustion engine, has an ignition device, which projects into the combustion chamber, this ignition device having at least one first pole and one second pole. The fuel jets emerging from the spray-discharge orifices spread an essentially cone-shaped fuel fan below the region of the ignition device. The end of the at least one first pole is arranged to the side adjacent to the end of the second pole projecting into the combustion chamber, and both ends are located on approximately the same level of the longitudinal axis of the ignition device.

Fuel injection system

In a method for operating an internal combustion engine of a motor vehicle, in particular, pressurized fuel is conveyed to a fuel accumulator. The fuel is injected into a combustion chamber via a fuel injector. Coking of the fuel injector is determined. A first fuel-pressure increase is implemented when the coking exceeds a threshold value.
