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.
Key words: Diesel
