The aim of this project is the evaluation of the effects of additives on soot formation from Diesel combustion processes. For the analysis of different additives a special Diesel-burner for combustion at atmospheric pressure was designed and manufactured. The soot formation process is mainly investigated by Laser-Induced Incandescence (LII) to determine soot volume fraction and primary particle size both in a 2-D imaging and a pointwise approach. While the pointwise measurements capture local concentration and size information simultaneously with high temporal resolution, the 2-D measurements allow for the characterization of the whole flame. As the aggregate size of the soot particles also determine their health impact, wide-angle light scattering (WALS) will be used for the characterization of aggregate size and morphology. By a combination of results from LII and WALS a comprehensive particle characterization is achieved. Furthermore, the effects of additives are assessed for a spray flame in a combustion chamber using high speed-video blackbody emission imaging and LII.
