An ignition system and a method for a spark-ignition combustion engine having a high-frequency plasma-augmented ignition spark, the spark ignition of the fuel being realized by at least one spark plug associated with a combustion chamber of the combustion engine. The spark plug has a prechamber having at least one opening via which the prechamber communicates with the combustion chamber on the fuel side, so that the ignition spark in the prechamber, into which the high-frequency plasma can be injected, induces the plasma-augmented spark ignition of the fuel in the prechamber.

The invention relates to a semiconductor body revolving around a main axis (A) for a spark plug of a turbine engine, the semiconductor body comprising a baseplate and an upper portion extending from the baseplate along the main axis, the baseplate comprising a bottom surface substantially defined in a plane perpendicular to the main axis and a first conical surface intended to cooperate by form-fitting at least partially with a contact surface of an outer electrode of the spark plug. According to the invention, the upper portion comprises an interface located opposite the bottom surface along the main axis (A) and featuring a profile that is at least partially corrugated.

A gaseous fuel injector for supplying gaseous fuel to a gaseous fuel combustion engine includes an injector housing which receives an injector assembly and supplies gaseous fuel thereto. The injector housing has an inlet at a first end, a nozzle with an outlet at a second open end and a chamber between the inlet and the outlet. The injector housing includes an ignition arrangement at the second open end.

A device may determine a timing configuration for an ignition system. The device may pulse a driver to apply a set of resonant voltage pulses to the ignition system. The set of resonant voltage pulses may cause a set of increasing peak voltages. At least one peak voltage, of the set of increasing peak voltages, may satisfy a threshold to cause a spark in a spark plug of the ignition system.
