Measurement of Diesel Exhaust Particles by LII and Evaluation of DPF

In this study, we measured PM concentration in diesel exhaust gas by laser-induced incandescence (LII). To evaluate the diesel particulate filter (DPF), the measurement was conducted at the point right after DPF exit. Four filters of different porosity and wall thickness were tested. In addition, EE...

Summary:In this study, we measured PM concentration in diesel exhaust gas by laser-induced incandescence (LII). To evaluate the diesel particulate filter (DPF), the measurement was conducted at the point right after DPF exit. Four filters of different porosity and wall thickness were tested. In addition, EEPS system was used to examine the particle number concentration and calibrate LII signals. Based on the time-variation of PM concentration, an initial PM filtration efficiency and soot cake formation in DPF were discussed. The LII technique can be potentially applied to find the location of PM leakage through the filter and evaluate the after-treatment system.
