The Effect of Evaporation Models on Urea Decomposition from Urea-Water-Solution Droplets in SCR Conditions

Selective catalytic reduction using urea-water-solution to reduce emissions of NO x from diesel engines is commonly used in the automotive industry. For a high efficiency of this process, a good understanding of the formation of ammonia from …

CFD Simulation of Liquid Back Suction and Gas Bubble Formation in a Circular Tube with Sudden or Gradual Expansion

To avoid potential damage of the dosing unit in selective catalytic reduction by freezing urea-water-solution, the liquid is usually drained from the delivery line when the vehicle is out of operation. When liquid is sucked back counter to the …

Model-Based Optimization of Ammonia Dosing in NH3-SCR of NO x for Transient Driving Cycle: Model Development and Simulation

The ability to catalytically reduce NO x efficiently with ammonia (NH3) has made the selective catalytic reduction (SCR) technology indispensable in diesel after-treatment systems. Ammonia is dosed periodically in the form of urea which decomposes …

Application of Surrogate Modelling to the Optimisation of Kinetic Parameters in an Emissions Control Catalyst Model Using Vehicle Drive Cycle Data

This work describes the application of surrogate modelling to the optimisation of kinetic parameters in a kinetic model of a vehicle emissions control catalyst using engine or vehicle test data. Optimisation using conventional methods with a …

Turbulence Decay Inside the Channels of an Automotive Catalytic Converter Monolith

This paper reports a multi-scale study of the turbulence decay inside of a monolith. It is a well-known fact that the turbulence at the automotive catalytic converters affects the conversion of chemical species, the composition of the exhaust gas …

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.

HyperForm® bietet leichte und kosteneffiziente Stähle für die gesamte Fahrzeugstruktur

Höhere Umformbarkeit verbessert Gewicht, Kosten und Leistung
Dank großer Anstrengungen und neuer Technologien zur Senkung der Abgasemissionen gelingt es den Automobilherstellern derzeit, die aktuellen internationalen Auflagen zu erfüllen. Als Schlüsseltechnologie auf Materialseite spielt der Fahrzeugleichtbau eine große Rolle. Hier verlagert sich der Fokus von der bloßen CO₂-Reduzierung hin zu einer zusätzlichen Verringerung der zugehörigen Kosten.
