Abstract (en)

[origin: WO8706977A1] The device comprises an incandescent body (22) located downstream of the injection nozzle and designed as a helix tappering outwards in the direction of the combustion chamber. The helix consists of a flat strip (22), whose spiral shape is cut out from a flat metal sheet (74) by means of a laser or for example an acid; it is then stretched in an axial direction. This design simplifies contact of the incandescent body (22) and has the further advantage that the incandescent body (22) can be made from special materials which can only be obtained in the form of flat plate or strip.
