    Abstract : Internal combustion engines are continuously developed towards decreased hazardous emissions and lower fuel consumption. The homogeneous charge compression ignition (HCCI) engine is a promising concept which combines the best features of the Diesel engine and the spark ignition (SI) engine. READ MORE

  5. 3. Laser Diagnostic Techniques with Ultra-High Repetition Rate for Studies in Combustion Environments

    Author : Jimmy Olofsson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-Speed; High Repetition Rate; LIF; PLIF; 3D Visualisation; Engine; Teknik; Technological sciences; Fysik; Physics; Combustion; Laserteknik; Laser technology; Laser-Induced Fluorescence; Laser Diagnostics;

    Abstract : When conducting laser based diagnostics in combustion environments it is often desirable to obtain temporally resolved information. This can be due to several factors such as combustion taking place in a turbulent flow field, flame propagation from a spark plug in an initially quiescent combustible mixture, or rapid, multi-point fuel consumption in a homogeneous charge as a result of compression ignition in an engine cycle.
