In spite of the high efficiency of the diesel engine there is still potential for further reduction of fuel consumption and emissions. Therefore, there is a need to improve the fundamental understanding of the very complex processes which take place throughout diesel combustion. This is the aim of the research programme association known as IDEA (Integrated Diesel European Action), which is supported by the automobile manufacturers Fiat, Peugeot, Renault, Volvo and Volkswagen, as members of the Joint Research Centre (JRC), by the Commission of the European Communities, and by the National Swedish Board for Industrial and Technical Development. The purpose of this paper is to demonstrate how in-cylinder flow analysis, by means of laser light-sheet techniques and Laser Doppler Anemometry (LDA), can help with the understanding of the interaction of swirl flow and combustion in a direct-injection diesel engine and thus support the development of engines with lower fuel consumption and emissions.
