Diesel Particulate Filter Modeling For Compression Ignition Engine

Abstract

Diesel particulate filters capture particle emissions through a combination of filtration mechanisms, such as diffusion deposition, inertial deposition, or flow-line interception.Collected particulates are removed from the filter, continuously or periodically, through thermal regeneration.Diesel filters are highly effective in controlling solid particulate emissions-including solid particle numbers-but may be ineffective in controlling liquid fractions of PM emission.Filters were first commercialized as retrofit devices, followed by a wide scale adoption on new light-duty and heavy-duty diesel engines in both highway and non road applications.
