Measurement of the main compounds present in the diesel particulate matter exhaust emissions generated from the real diesel combustion engine passenger vehicles

In this research we apply Laser Induced Breakdown Spectroscopy technique for diagnostics of Diesel Particulate Matter - DPM formed from combustion Diesel engine - exhaust emissions. Particularly we are concern with the measurements of main chemical components of particulate matter, from actual Diesel engine passenger vehicles. Here we analysed DPM from different Diesel engine passenger vehicles of major EU brands car producers used in daily life environment by LIBS technique. The aim of this study is to reveal the compounds, which are mostly present in the Diesel engine exhaust emissions and can affect the overall composition of the DPM. The presence of these elements in exhaust emission may point to different processes, mainly to fuel quality, insufficient engine combustion process, incomplete catalytic reaction, inefficient Diesel particulate filtering technique, or failure in the Diesel engine.
