1. diesel particulate filter system comprises:

  • A) be positioned at the pressure transducer of described diesel particulate filter inlet side;

    B) control module that is connected with described pressure transducer, and described control module is mounted with at least one look-up table;

    WithC) have the low pressure that lags behind and fall look-up table, it is associated the soot load amount in described diesel particulate filter with the pressure variation of measuring by pressure transducer;

    Wherein, when the soot load of diesel particulate filter reached the soot load that presets, described control module started regenerative cycle.
