Abstract
System-level models containing engine model, emission models,
and aftertreatment device models have been developed. All the
sub-models have been developed separately and come from a variety
of different sources. A new phenomenological CO model recently has
been coupled into the previous integrated model. The emission
models, including PM (particulate matter), NOx, and CO
are also calibrated from experimental data. Some modification has
been added to improve the integrated model and accept different
aftertreatment device models for future work. The objective of this
work is to study the DPF (Diesel Particulate Filter) regeneration
during transient operating conditions using the integrated
model.
The integrated system-level model is used to studying the
dynamic performance between engine and aftertreatment system. In
this study, the calibrated emission models are validated at
transient operating conditions. Passive and active DPF
regenerations are also conducted for load and speed transients to
study the transient effects on regeneration. The effects of exhaust
mass flow rate, and temperature on pressure drop across the DPF
during regeneration are investigated.
