Development of Tire-Wear Particle Emission Measurements for Passenger Vehicles

In this study, we aimed to develop a new method for measuring tire-wear particles of less than 2.5 μm generated from vehicle use. We also aimed to devise a method for evaluating the emission factor of tire-wear particles. To develop an evaluation …

Application of a Diffusion Charger to Quantify Real-Time Particle Emissions from Light-Duty Vehicles: a Comparison Study with a Particle Size Spectrometer

Measurement methods for vehicle-emitted particulate matter (PM) have evolved as vehicle emission standards have become more stringent. For example, the filter-based gravimetric method has been demonstrated feasible to measure emissions at levels …

Modeling and Optimization of Multi-functional Ammonia Slip Catalysts for Diesel Exhaust Aftertreatment

Ammonia slip catalysts (ASC) are used downstream of the NH3-selective catalytic NOx reduction (SCR) system, to minimize ammonia slip from transport sector SCR units. The ASC may consist of an SCR active layer for NOx control, a layer with …

Lean-Burn Natural Gas Engines: Challenges and Concepts for an Efficient Exhaust Gas Aftertreatment System

High engine efficiency, comparably low pollutant emissions, and advantageous carbon dioxide emissions make lean-burn natural gas engines an attractive alternative compared to conventional diesel or gasoline engines. However, incomplete combustion …

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.
