Special Issue Information

Dear Colleagues,

This Special Issue focuses on advancing the understanding of vehicle emissions through real-world testing, sophisticated modeling techniques, and comprehensive lifecycle evaluation. It explores measurement methods for capturing accurate emissions data, innovative modeling approaches to predict and analyze patterns of emissions, and lifecycle assessment to evaluate the environmental impact of motor vehicles from production to the end-of-life stage. Submissions are encouraged on topics including, but not limited to, the following:

  • Real-world measurement techniques for vehicle emissions;
  • Advanced modeling methodologies for prediction and analysis of emissions;
  • Lifecycle assessment frameworks for evaluating vehicle emissions and their environmental impact;
  • Integration of testing and modeling for policy and mitigation strategies;
  • Case studies on emissions reduction and sustainable vehicle technologies.

In the context of increasingly stringent vehicle emission regulations, computer-aided engineering has been indispensable for optimizing the design and the operational strategies of emission control systems. This paper proposes a new filtration model for particulate filters that enables the accurate estimation of solid particle number emissions above 10 and 23 nm in diameter (SPN10 and SPN23, respectively). The model incorporates a persistent slip factor and a linear filtration efficiency of cake layers into the unit collector model proposed by Konstandopoulos and Johnson. This enhancement captures PM escape phenomena, such as a passage through interconnected large pores in filter walls. Simulations using a 1D + 1D two-channel framework with the proposed model successfully reproduced experimental results of SPN10 and SPN23 emissions downstream of a miniature gasoline particulate filter (GPF) tested with a synthetic particle generator. The model was also able to represent the observed continuous emissions during a cake filtration mode. Additional simulations using the same model parameters showed good agreement with experimental data of SPN10 and SPN23 emissions downstream of a full-size GPF tested with a gasoline direct injection (G-DI) engine under 5 steady-state operating conditions. The simulations revealed that particles in the 10–100 nm size range dominated the downstream SPN emissions despite their high filtration efficiency, whereas particles in the 100–200 nm size range were less significant. The proposed model is expected to contribute to the GPF developments to comply with the stringent emission regulations of the upcoming Euro 7. Full article
