ABSTRACT:
A burner for hard-to-ignite mixtures, such as with exhaust gases of an internal combustion engine, in which an ignitable mixture is prepared in a locally limited area for producing an ignition flame that is then used for igniting the hard-to-ignite mixture. According to one embodiment, the burner has an auxiliary ignition burner that is integrated into the actual burner and that is operated with compressed air, which is delivered either by a vehicle compressed air system or by a separately provided air compressor. In an alternative embodiment, air is fed in, additionally, by an air injection device to an outlet area of the fuel nozzle and in the vicinity of the ignition device to prepare an extremely ignitable mixture in this area, which is used to generate an ignition flame. The air injection device can be supplied with compressed air in the same manner as for the auxiliary ignition burner in the first embodiment. Alternatively, ambient air with sufficient oxygen content can be fed in through the air injection device.
