PURPOSE: A reproducing system for a diesel particulate filter is provided to simplify a structure and a control logic thereof and to reduce manufacturing cost by adopting a nitrogen dioxide direct injection technique. CONSTITUTION: A reproducing system reproduces a diesel particulate filter(5) by burning particulate matters stacked on the diesel particulate filter(5). In order to burn particulate matters stacked on the diesel particulate filter(5), nitrogen dioxide is injected into an inlet of the diesel particulate filter(5). A pressure detecting device(15) detects pressure at the inlet and an outlet of the diesel particulate filter(5). A control section(18) receives a pressure signal from the pressure detecting device(15) and calculates differential pressure between the inlet and the outlet of the diesel particulate filter(5). An injector(13) is provided to inject nitrogen dioxide towards the inlet of the diesel particulate filter(5).
