Modelling of Mass Transfer Resistances in Non-uniformly Washcoated Monolith Reactors

There are various methodologies to account for mass transfer within non-uniformly distributed washcoats in monolith reactors in 1D models (axially). However, 1+1D models (axially/radially) fail to capture local variations in mass transfer from …

Calibration Uncertainty of 23nm Engine Exhaust Condensation Particle Counters with Soot Generators: a European Automotive Laboratory Comparison

Calibration of condensation particle counters (CPC) to measure non-volatile particle number (PN) from vehicle emissions is a significant source of uncertainty of the regulated particle number measurements. In this work, the calibration uncertainty …


Investigation of the Collected Soot Powder: Thermal Kinetics Analysis, γ-Radiation Treatment, and Clean Environment

The objective of this study is to identify the possibility of the collecting soot in industrial fields and removing its harmful products by the treatment of gamma irradiation. Experimental study is investigated on the collected soot using X-ray …


A Destruction Mechanism of a Three-Way Catalyst Due to a Failure of Fuel Supply in a Spark Ignition Engine

Misfires and fuel shutdown have similar features and affect similarly on overheating the three-way catalyst (TWC). In practice, this similarity is an obstacle to determining whether the misfires or fuel shutdown cause failure of the TWC.

Über diese Zeitschrift

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.
