Numerical Calculation of PM Trapping and Oxidation of Particulate Filter
In recent years, emission regulations have become more stringent, and particulate matter (PM) emitted from gasoline engine vehicles is also subject to regulation. PM emitted from a gasoline engine is suppressed by a gasoline particulate filter (GPF). However, unlike diesel engines, exhaust from gasoline engines flows into the GPF under more stringent conditions. Therefore, in this study, the authors performed numerical calculations based on WLTC, taking into account fluctuations in exhaust gas from gasoline engines, and confirmed the behavior of PM deposition and regeneration. At that time, the numerical calculation model of the previous research was also improved. Furthermore, a catalyst was supported on the GPF, and the catalyst performance was evaluated. As a result, it was suggested that continuous regeneration would be possible by improving the performance of the catalyst.
