Abstract

Ceramic particulate filters have become indispensable components of internal combustion engine aftertreatment systems to meet the stringent PM and PN emission regulations. Accurate modeling and simulating of the filtration performance of ceramic filters under transient cycles have been proved to be quite challenging. In the present study, a new filtration model based on discrete pore size distribution was developed to predict both the clean and loaded states filtration performance. New correlations and equations have been derived to describe the filtration efficiency when polydisperse cells are loaded with soot in the transient cycles. Systematic experiments of both natural gas and diesel engines have been conducted with CPC and EEPS measurements. It is demonstrated that the simulated results with the new filtration model agree quite well with the filtration data at different loading conditions and engine operating cycles. This new dynamic filtration model incorporating flow, filtration, and catalytic reaction can provide high-fidelity guidance in practical filter design and development.
