Difference in the Tailpipe Particle Number by Consideration of Sub-23-nm Particles for Different Injection Settings of a GDI Engine

The purpose of this study was to investigate the characteristic of nanoparticles under consideration of sub-23-nm particles from a 1.8-l direct injection (DI) gasoline engine under stoichiometric air/fuel conditions in the exhaust gas system. For …

Pressure Response during Filtration and Oxidation in Diesel Particulate Filter

Combustion-generated soot particles that arise from diesel vehicles are known to cause substantial damages to the environment as well as to human health. A diesel particulate filter (DPF) is needed to trap nanoparticles in the diesel exhaust …

An Asymptotic Solution for Washcoat Pore Diffusion in Catalytic Monoliths: Reformulation and Extension to Small Concentrations

A recent publication (Bissett in Emission Control Sci. Technol. 1(1), 3–16, 2015) proposed an alternative to the so-called 1 + 1D modeling of aftertreatment reactors with nontrivial washcoat pore diffusion. Rather than numerically solve the 1D …

Improving Methodology of Particulate Measurement in Periodic Technical Inspection with High-Sensitivity Techniques: Laser Light Scattering Photometry and Particle Number Method

First, the validity of the current test procedure for particle measurement adopted in a periodic technical inspection (PTI) was evaluated by comparing test results obtained with the PTI and a type approval test (TAT) procedure using a Euro V level …

About this journal

Emission Control Science and Technology is a forum for publication of the latest research on control of emissions from mobile and stationary sources. Papers are also welcome on various aspects of development and technology. The investigation may be experimental, theoretical, or computational.

Articles must survive rigorous peer review before they are considered for publication. Examples of topics that may appear in the journal include:

  • Emission control in mobile (road, land, sea, air) and stationary (e.g. power generation, industrial processes) applications.
  • Materials for and formulations of novel substrates and catalysts, such as those used in Diesel Oxidation Catalyst (DOC), Three Way Catalysts (TWC), Diesel Particulate Filters (DPF), Selective Catalytic Reduction (SCR), Lean NOx Trap (LNT), combined catalysts (e.g. DPF+SCR or DPF+LNT in one substrate), slip catalysts, or reformer catalysts.
  • Performance of emission control system components such as sensors, injectors for fuel and reducing species, exhaust inserts and mixers, etc.
  • Effects of operational parameters (e.g. flow, temperature, species concentration) and design approaches (sizing, layout, insulation, etc) on regulated and unregulated emissions and emission control system efficiency and performance.
  • Basic and applied research on specific components (e.g. nanoparticles, N2O and other non-regulated pollutants) of emissions and their mitigation.
    System considerations such as engine-out to tailpipe efficiency, optimization, PGM management, and formation of secondary species.
  • Engines, combustion, fuels, or lubricants as they would affect emission reduction technologies or post combustion processes.
  • Testing, durability and compliance such as cycles, certification, aging, NVH, in-field (on-vehicle) performance and analysis, and in-use compliance.
    Analysis of current and future emission regulations (including those in the developing world).
  • Biological and environmental effects of emission control technologies.
