Abstract

The invention relates to an ignition device for igniting a gas mixture in a main combustion chamber (1), especially an internal combustion engine. According to the invention, an absorber body (5) is heated by means of a laser (8). In order to improve the ignition behaviour, a preliminary chamber (10) is mounted upstream of the absorber body (5) on the inner side (6) of the combustion chamber.

Abstract

The invention relates to a spark plug for igniting a combustible gas mixture in an internal combustion engine, comprising an ignition electrode (4), an electrical supply line (5), to which the ignition electrode (4) is connected, an insulator body (6), through which the supply line (5) is passed, a housing head (2), which rests in sealing fashion on the insulator body (6) and bears an outer thread (3) for the purpose of screwing it into an internal combustion engine, a tube housing (9), which is fixed on the housing head (2), surrounds the insulator body (6) and has a hexagon head (13). The invention provides that the tube housing (9) surrounds an insulator body holder (7), which is welded to the housing head (2) and presses the insulator body (6) with a prestress against the housing head (2).

IPC Classes  ?

• H01T 13/36 - Sparking plugs characterised by features of the electrodes or insulation characterised by the joint between insulation and body, e.g. using cement
• H01T 13/54 - Sparking plugs having electrodes arranged in a partly-enclosed ignition chamber
