CATALYTIC BURNER SYSTEM FOR DPF REGENERATION |
摘要 |
A system and method of effective regeneration of a diesel particulate filter used in the exhaust system of a diesel engine during low engine operating temperatures, is disclosed. Generally speaking, a catalytic burner system and method used in filter regeneration on a diesel engine comprises a burner diesel oxidation catalyst (BDOC) coupled to an exhaust flow of the diesel engine, a mixer fluidly coupled to the BDOC, a diesel oxidation catalyst (DOC) fluidly coupled to the mixer, and a diesel particulate filter (DPF) fluidly coupled to the DOC, wherein the BDOC directs the exhaust flow through the mixer, the DOC and the DPF during a regeneration cycle of the DPF under low engine temperature operating conditions. |

1. A catalytic burner system for use in regeneration of a filter in an exhaust system on a diesel engine, the burner system comprising:
a burner diesel oxidation catalyst (BDOC) having an inlet for receiving an exhaust flow from the diesel engine and an outlet at an opposing end; a mixer fluidly coupled to the outlet of the BDOC; a diesel oxidation catalyst (DOC) fluidly coupled to the mixer; and, a diesel particulate filter (DPF) fluidly coupled to the DOC, wherein the BDOC channels the exhaust flow through the mixer, the DOC and the DPF during a regeneration cycle of the DPF under low engine temperature operating conditions. |
