Soot particles accumulated in a DPF should be removed after a certain service time due to high pressure drop. The most common method is oxygen active regeneration which causes high fuel penalty and sometimes DPF cracking or melting. In this study, the authors aim to investigate the low temperature regeneration with hydrogen, which could prolong the DPF lifespan and facilitate CDPF regeneration efficiency. The DPF used in this research was coated with Pt/Al₂O₃ 25g/ft³ and all experiments were performed on engine test bench. Results showed that hydrogen in exhaust gas can be ignited at about 120℃ and regeneration can be realized at about150℃ or even lower. There was a large temperature drop (about 40℃) at the front end of DPF after hydrogen oxidized. DPF maximum inside temperatures depend on the hydrogen concentration. Therefore, the DPF maximum inside temperature can be controlled by the supplied hydrogen concentrations.
