Design and Experimental Research on Evaporation-Type DPF Regenerative Burner

Abstract

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.

Estimation of the Diesel Particulate Filter Soot Load Based on an Equivalent Circuit Model

“…As emission regulations become more stringent, diesel engines must be equipped with aftertreatment systems to meet emission requirements [2,3]. The diesel particulate filter (DPF) is the most effective technique to reduce PM emissions [4]; it can capture more than 90% of PM [5][6][7] with many parallel channels inserted at both ends to force the exhaust gases through the porous ceramic walls [8]. However, with the gradual accumulation of PM in the DPF, the exhaust manifold back pressure of the engine gradually increases, which leads to the decline of engine efficiency, and increases fuel consumption [9].…”
