  • Patent number: 5140814
    Abstract: An exhaust gas system with a particulate filter and a regenerating burner, whose hot gas outlet is provided in the vicinity of a closed end of the filter in the form of a plurality of openings, which are arranged in one or more planes parallel to the entry surface of the particulate filter. Due to the splitting up of the hot gas flow in the burner into a plurality of smaller flows of hot gas, the mixing with the exhaust gas is so improved that directly downstream from the flame tube of the burner there is a substantially complete equalization of temperature whereby the particulate filter may be positioned very close to the burner.
