Abstract
This work presents the experimental investigation of Diesel
Particulate Filter (DPF) regeneration and a calibration procedure
of a 1D DPF simulation model based on the commercial software AVL
BOOST v. 5.1. Model constants and parameters are fitted on the
basis of a number of steady state DPF experiments where the DPF is
exposed to real engine exhaust gas in a test bed. The DPF is a
silicon carbide filter of the wall flow type without a catalytic
coating.
A key task concerning the DPF model calibration is to perform
accurate DPF experiments because measured gas concentrations,
temperatures and soot mass concentrations are used as model
boundary conditions. An in-house-developed raw exhaust gas sampling
technique is used to measure the soot concentration upstream the
DPF which is also needed to find the DPF soot burn rate. The soot
concentration is measured basically by filtering the soot mass of a
sample gas continuously extracted from the engine exhaust pipe for
1-2 hours while also measuring the gas flow passed through the
filter. A small silicon carbide wall flow DPF protected in a sealed
stainless steel filter housing is used as sample filter.
Measured DPF pressure drop characteristics are used to fit model
constants of soot and filter properties. Measured DPF gas
conversions and soot burn rates are used to fit model activation
energies of four DPF regeneration reactions using O₂ and NO₂ as
reactants. Modeled DPF pressure drops and soot burn rates are
compared to the steady state DPF experiments in the temperature
range between 260 and 480°C. The model widely reproduces the
experimental results. Especially the exponential soot burn rate
versus temperature is accurately reproduced by the model.
