Particle Number Emissions During Regeneration of DPF-equipped Light Duty Diesel Vehicles A Literature Survey
The study reviews published work on the particle emissions during regeneration of diesel particulate filters in anattempt to assess the PMP methodology under these operating conditions. During regeneration of the DPF asignificant increase of the emitted number of particles is observed. Size spectra reveal a nucleation modepeaking at approximately 10 nm, at concentrations that ca...

متن کاملTime resolved characterization of diesel particulate emissions. 1. Instruments for particle mass measurements.
The measurement of diesel vehicle exhaust particulate mass is currently accomplished using filter collection methods according to the Code of Federal Regulations (CFR). Such filter methods limit time resolution to a minimum of several minutes, making it impossible to study emissions during transient operating conditions. Extensive testing of five different measurement methods has demonstrated t...
متن کاملComparison of Particle Number and Mass Emissions from Diesel Transit Buses across Temporal and Spatial Scales
Two common metrics of particle pollution measure the total number of particles (particle number) and the total mass of the particles (particle mass). This work analyzes particle number and mass emission rates measured from the exhaust of a 2002 diesel transit bus in real-driving conditions using on on-board mini-dilution system. The number concentrations were measured using the Electrical Low P...
متن کاملModeling 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...
