Design and Experimental Research on Evaporation-Type DPF Regenerative Burner

Diesel engine for automobile mainly adopts diesel particulate filter (DPF) method to deal with the exhaust particulate. In order to eliminate the particulate in the filter and complete DPF regeneration, the burner needs to be set at the entrance of DPF. This paper designs the evaporation-type DPF regenerative burner, and makes the bench and the real vehicle test. The test shows that the burner can complete DPF regeneration well within the working scope of the larger engine.
