Current status and new concepts of gasoline vehicle emission control for organic metallic, and particulate non-legislative pollutants (GASOMEP)

In the next decades, we will be exposed to exhausts of gasoline direct injection (GDI) vehicles with yet unknown consequences. But we have the choice to equip these vehicles with catalytic filter technology or not. The GasOMeP project will investigate the emission characteristics of various GDI vehicles and evaluate the potential of gasoline particle fi lters (GPF) currently developed by our industrial partners. A wide spectrum of gaseous and particle-bound pollutants is studied for different GDI vehicles which are operated without and with fi lter technology and fossil fuels or biofuels. Particle emissions including their size distribution, number and metal content will be characterized in detail. Emissions of semi-volatile compounds including genotoxic constituents like polycyclic aromatic hydrocarbons (PAH), their alkylated, nitrated and oxygenated forms will be studied. These compounds are important precursors of secondary organic aerosols (SOA) which form in the atmosphere. Respective SOA forming potentials will be investigated with smog chamber experiments and two independent fl ow reactor approaches.
