Abstract (en)

[origin: WO03042533A1] The invention relates to an ignition system for an internal combustion engine comprising at least two microwave injection elements (f1, f2) which are provided in the combustion chamber (1) and are fed by a microwave generator (a). The microwaves supplied by the microwave generator produce interferences in the combustion chamber (1), by which means the necessary ignition energy is made available by superposition. The phase displacement between at least two microwaves sent by different injection elements (f1, f2) can be modified, in addition to the amplitude and the frequency of said microwaves. According to the inventive method for igniting an at least locally explosive fuel-air mixture in a combustion chamber (1) of an internal combustion engine by means of one such ignition system, the location of the ignition in the combustion chamber is regulated in a targeted manner, by variation of at least one of the cited parameters. The necessary ignition energy can thus be made available at a plurality of locations and/or a plurality of moments.
