Device for generating a hot gas in an exhaust system of a combustion engine

摘要

The device has a burner chamber housing (14) with primary burner chamber (27) and coaxial vortex atomiser nozzle. A secondary burner chamber (28) forms an extension of the primary burner chamber. A fuel inlet (35) opens into the exhaust stream of the engine and this supplied fuel burns with the oxygen contained in the engine exhaust gases in the secondary burner chamber. A mixer (13) is mounted in the gas stream behind the secondary burner chamber.
