【 摘 要 】

A DPF two-channel tail gas treatment device was designed in this paper basing on the DPF regeneration technology of marine diesel engine, and the regeneration characteristics of the ordinary electric heating and DOC-assisted DPF electric heating are compared. Furthermore, the power and the regeneration rate of the regeneration unit. The results demonstrate that the DOC-assisted two-channel electric heating energy DPF could effectively reduce the regenerative power, increase the regeneration rate, so it is suitable for application in marine diesel engines.
