The IEA provides support for international collaboration on energy technology R&D, deployment and information dissemination. These groups function within a framework created by the IEA - the International Framework for International Energy Technology Collaboration. The views, findings and publications of these international groups (formally called Implementing Agreements) do not necessarily represent the views or policies of the IEA Secretariat or of all its individual member countries. OECD Member countries, autonomous OECD non-member countries, intergovernmental organisations, non-governmental organisations and private sector entities may participate. For more information, see our Technology Agreements page.

Emissions Reduction in Combustion

Understanding of combustion processes is fundamental to achieving further improvements in fuel use efficiency, reducing the production of pollutants such as nitrogen oxides, and easing the transition to alternative fuels. The goal of the Implementing Agreement on Energy Conservation and Emissions Reduction in Combustion is to accelerate the development of combustion technologies that demonstrate reduced fuel consumption and have lower pollutant emissions. The focus on emissions is primarily concerned with toxic or noxious emissions, rather than greenhouse gases, although improved combustion efficiency will lead to a reduction in emissions of carbon dioxide. The work programme includes:

- studies for improving the efficiency and fuel flexibility of automobile and truck engines

- improving the performance of industrial furnaces

- studies in emissions formation and control mechanisms and in fuel injection and fuel/air mixing 

- investigations of the fundamental physical phenomena relevant to the combustion process 

Industrial involvement insures attention to industrial needs and the dissemination of technology to the marketplace. One of the main achievements has been the development of robust diagnostic capabilities, such as the Laser Induced Fluorescence and the improved Computational Fluid Dynamics and Chemical Kinetics codes. The work programme is conducted through task-sharing and information exchange between participants. Participants also undertake collaborative work at each others’ facilities.  Multi nation collaborations include work in Hydrogen Combustion, Alternative Fuels, Particulate Diagnostics, Fuel Sprays, Gas Turbines, and Advanced Combustion Processes such as Homogeneous Charge Compression Ignition (HCCI).

Current Projects (Annexes)

Area 1. Advanced Piston Engine Technology
The objective of the cooperative work in this Area is the development of combustion technology, both analytical and experimental, that will provide imporved models for advanced internal-combustion piston engines, namely lean homogenous-charge, stratified-charge, and diesel engines. The research will contribute primarily to technology common to these engine concepts and will provide data bases and descriptive and predictive system codes, in addition to practical demonstrations.

 

Area 2. Advanced Furnace Technology
The objective of the cooperative work in this Area is the development of combusion technology, both analytical and experimental, that will provide models for furnaces and boilers. The research will provide a data base and descriptive and predictive system codes, as well as practical demonstrations.

 

Area 3. Fundamentals
The objective of the cooperative work in this Area is to conduct theoretical investigations of the fundamental physical phenomena relevant to the combustion process as is called for in Areas 1, 2 and 4, and to support the development of new diagnostic techniques for application in the future.

 

Area 4. Advanced Gas Turbine Technology
This Area was created by the Executive Committee to identify work related to the development of combustor and gas turbine modeling and verification, to the study of emissions formation and control mechanisms, and to practical studies in fuel injection and fuel/air mixing.

 

Area 5. Supporting Activities
The objective of the cooperative work in this area is to provide administrative support and services as are called for by the cooperative work in the Areas above.
