| Abstract:The method of DPF regeneration by injecting fuel into tail pipe with the temperature of the front end of the DPF as the control objective is presented. The system composition, its control strategy and the test of DPF regeneration are described in details. The test results indicate that the PM on the interior surface of the DPF can be removed effectively with this system and the DPF's function of filtrating PM can be restored. |
