  • Patent number: 8621851
    Abstract: A particle filter arrangement for filtering exhaust gases of an internal combustion engine such as a diesel internal combustion engine, includes an inlet and an outlet and at least one particle filter arranged in the flow path of the exhaust gases between the inlet and outlet. The exhaust gases are conducted in a line, with the line having a first segment in which the exhaust gases are conducted substantially in the direction of the outlet. The line has a second segment in which the exhaust gases are conducted substantially in the direction of the inlet. An operating temperature of the arrangement sufficiently high to prevent full loading of the filter is generated particularly quickly in that the line also includes a third segment in which the exhaust gases are conducted substantially in the direction of the outlet.
