초록 ▼

Four design variants of a full-flow burner for the thermal regeneration of a particle filter in an exhaust gas aftertreatment system of an internal combustion engine, especially a diesel engine, which is arranged fully in the tailpipe, especially in an expanded, straight coaxial tailpipe section, are suggested according to the present invention. As a result, the flow can enter a particle filter axially, which means simplified design and good temperature distribution. The full-flow burners are preheated by the heat of the exhaust gas of the engine during the start phase. The exhaust gas of the engine cools the burner surface during the phase of burner operation, so that thermal overload is avoided.

[ What is claimed is:] [1.] A burner for the thermal regeneration of a particle filter arranged in a tailpipe of an internal combustion engine, the burner comprising:a tailpipe section of increased diameter;a vaporizing combustion chamber disposed centrally and coaxially with respect to said section of increased diameter, said vaporizing combustion chamber including a closed, arched flow inlet end in an upstream direction relative to exhaust gas flow and having an opening in a downstream direction, said section of increased diameter cooperating with said vaporizing combustion chamber to define a jacket space comprised of a substantially annular exhaust gas flow passage, disposed around said vaporizing combustion chamber, on a jacket circumference of said vaporizing combustion chamber, said gas flow passage having a substantially constant magnitude from said inlet end to said opening in said downstream direction. [25.] A burner for the thermal regeneration of a particle filter arranged in a tailpipe of an internal combustion engine, the burner comprising:a tailpipe section having a diameter larger than a diameter of the tail pipe;a combustion chamber disposed in said tail pipe section, said combustion chamber being arranged completely in said tailpipe section, said combustion chamber including a closed, arched flow inlet end in an upstream direction relative to exhaust gas flow, and a downstream end defining an opening, said section of increased diameter cooperating with said combustion chamber to define an annular exhaust gas flow passage disposed around said combustion chamber, and on a jacket circumference of said combustion chamber, said annular exhaust gas flow passage having a substantially constant magnitude from said inlet end to said downstream direction.
