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 being 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 in order to achieve the stringent emission targets.

When designing exhaust aftertreatment systems for renewable sustainable fuels, unconventional exhaust components and new boundary conditions (composition, pressure, temperature) must be considered. Understanding these conditions is crucial for the proper design and layout of system components.

The work is a collaborative effort among Task participants from both the AMF and Sustainable Combustion TCPs.

The scope of work includes the following activities:

• 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.

Austria contributes to WP1 (Characterization of the exhaust profiles) and is also responsible for task management and dissemination.

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.
