In this study we apply Laser Induced Breakdown Spectroscopy technique for qualitative and quantitative spectrochemical analysis of Diesel Particulate Matter (DPM) emitted form in-use Diesel combustion engine exhaust emissions. We analysed particulate matter from sixty-seven Diesel engine passenger vehicles of major EU car producers usid in daily life environment. The aim of this study is to compare Particulate Matter (PM) composition mainly agglomerated major and minor chemical elements. Especial attention is given to analyse different PM and perform a quantification and calibration of LIBS spectral signal. The presence of agglomerate chemical elements in Diesel exhaust emissions are due to different processes involved within the combustion. These are mainly related to the Diesel fuel, fuel additives, engine performance, applied aftertreatment devices like selective catalytic reduction devices and Diesel particulate filtering techniques. All these input parameters influence the final chemical composition of exhaust emissions a well as the Diesel particulate matter emitted from in-use Diese engine vehicles.
