IEA AMF Task EATS: Exhaust gas aftertreatment systems (working period 2024 - 2027)

Internal combustion engines with renewable fuels are indispensable for the decarbonization of the hard-to-electrify industrial and transport sectors. The AMF TCP EATS Task is investigating effective exhaust aftertreatment technologies to achieve air quality comparable to electrified applications. Emissions are being analysed, suitable measurement methods identified and guidelines for limiting emissions developed.

Short Description

The aim of the IEA AMF EATS Task is to develop and implement technologies to reduce emissions from internal combustion engines (ICE) running on renewable fuels.

The ICE emissions are increasingly regulated depending on the respective application. While previously only certain pollutant emissions were generally limited, climate-relevant exhaust gas components are now increasingly included in emissions regulations. In the case of ICE, greenhouse gas emissions can be massively reduced by replacing fossil fuels with climate-neutral fuels. The type of fuel has a significant influence on pollutant emissions, so that specific engine-internal measures and suitable exhaust aftertreatment systems (EATS) must be used depending on the choice of fuel to achieve the stringent emission targets.

When designing exhaust aftertreatment systems for renewable fuels, it is increasingly necessary to address unconventional exhaust components and new boundary conditions (e.g., exhaust composition, pressure, and temperature). A thorough understanding of the prevailing conditions in the exhaust gas is crucial for the layout and arrangement of the individual components of the exhaust aftertreatment system.

The task involves the following points:

  • Characterization of the exhaust profiles for renewable fuels such as ammonia and methanol through experimental investigations.
  • Validation and evaluation of measurement methods such as FTIR, GC and FID to capture total hydrocarbons and specific compounds.
  • Investigation and evaluation of catalytic exhaust aftertreatment systems to reduce new pollutant components in exhaust gases.
  • Development of recommendations for regulatory authorities to effectively limit emissions and promote the adoption of environmentally friendly technologies.

Expected results:

  • Detailed emission profiles for climate-neutral fuels
  • Customized exhaust aftertreatment systems that significantly improve pollutant emission reduction.
  • New, reliable methods for quantitative analysis of unconventional exhaust gas components and validation of the effectiveness of exhaust aftertreatment systems.
  • Well-founded, evidence-based recommendations for compliance with emission regulations, supporting the implementation of environmentally friendly technologies.

The results will be processed accordingly and made available in an appropriate manner to the relevant stakeholders, such as national and local authorities, policymakers, NGOs, engine and component manufacturers, providers of measuring and analysis equipment, exhaust aftertreatment system suppliers as well as the fuel and lubricant industry.
