Modeling of Diesel Particulate Filter Regeneration: Effect of Fuel-Borne Catalyst

Modeling of diesel particulate filter filtration and regeneration for transient driving schedules

Modeling of the Regeneration Processes in Diesel Particulate Filters

New simulation algorithm of soot oxidation in diesel particulate filter (DPF) is proposed. Two-dimensional finite differences scheme is used for calculation of the heat transfer in DPF (macro-scale). One dimensional model for treatment of the soot oxidation process in a separate filter channel (micro-scale) is based on a new expression for the oxidation reaction rate that is a modification of t...

A 2-D Diesel Particulate Regeneration Model

Diesel particulate filter (DPF) has been widely applied as the efficient way to reduce the soot emissions from diesel engines. The oxidation of the accumulated soot layer in the particulate filter, known as DPF regeneration, plays a crucial role in the diesel engine operation. It is important to understand the characteristics and fundamentals of this process. A 2D timedependent diesel particula...

Effects of a diesel particulate � filter regeneration process on aerosols in an underground mine �

This study was conducted to evaluate the effects of a diesel particulate filter (DPF) regeneration process on the concentrations and size distributions of aerosols in an underground mine. Two active regeneration strategies were examined for an electrically regenerated sintered metal fiber filtration system, and the effects were compared with those observed for a muffler and the same system oper...

Loading and Regeneration Analysis of a Diesel Particulate Filter with a Radio Frequency-Based Sensor

Accurate knowledge of diesel particulate filter (DPF) loading is critical for robust and efficient operation of the combined engine-exhaust aftertreatment system. Furthermore, upcoming on-board diagnostics regulations require on-board technologies to evaluate the status of the DPF. This work describes the application of radio frequency (RF) – based sensing techniques to accurately measure DPF s...
