Abstract In order to effectively implement DPF (Diesel Particulate Filters)
regeneration control, thermal management of exhaust products before and inside
Diesel Oxidation Catalyst (DOC) is necessary. In the present study, the Influence
of the intake throttle valve and late post injection process on temperature rise
inside DOC is analyzed through engine bench tests. The steady experiment results
show that adjustment of the intake throttle valve can effectively increase exhaust
temperature before DOC; in particular, with intake throttle valve opening at 20%,
temperature before DOC can be increased by about 170°C with respect to the full
opening. An increase in the late… More >
