Understanding of combustion processes is fundamental to achieving further improvements in fuel use efficiency, reduce the production of pollutants such as nitrogen oxides, and ease 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 for use by industry 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 -developing calculation procedures, instrumentation and information to reduce the excess air level required in furnaces -studies in emissions formation and control mechanisms and in fuel injection and fuel/air mixing for gas turbines -investigations of the fundamental physical phenomena relevant to the combustion process high degree of 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.
