Abstract: The key problem of the application of the heated regeneration system of diesel exhaust particulate filter is the reliable regeneration of the filter, and that the reliable regeneration of the particulate filter will depend on the effective control of the regeneration process. According to the need of the application of the electrical heated regeneration system of the diesel exhaust particulate filter, a control idea by using the exhaust flow to control the regeneration process of the filter is proposed. On the basis of the analysis of the factors affected the filter electrical heated regeneration process, the control system of the electrical heated regeneration system of diesel particulate filter is designed and the control strategy of the regeneration system is put forward.
