1. a kind of diesel particulate filter system, comprising:

  • A) diesel particulate filter of the soot load with substantially linear and the figure of pressure drop;

    Wherein substantially linear refers to instituteState figure at least 70% is linear;

    B) it is located at the pressure sensor of the diesel particulate filter entrance side;

    C) control module being connect with the pressure sensor, and the control module is mounted with one or more consult tables;

    WithD) at least one of described consult table is pressure drop consult table, and the cigarette ash for considering diesel particulate filter is negativeThe deviation of load, and the soot load amount in the diesel particulate filter is become with the pressure measured by pressure sensorChange associated;

    Wherein, when the soot load of diesel particulate filter reaches presetting soot load, the control module startingRegeneration cycle;

    Wherein the diesel particulate filter is acicular mullite without identification layer.
