- Summary:
- In the present paper some results of investigations of nanoparticles from five DI gasoline cars are represented. The measurements were performed at vehicle tailpipe and in CVS-tunnel. Moreover, five variants of "vehicle - GPF" were investigated. These results originate from the project GasOMeP (Gasoline Organic and Metal Particulates), which focused on metal-nanoparticles (including sub 20nm) from gasoline cars with different engine technologies.The PN-emission level of the investigated GDI cars in WLTC without GPF is in the same range of magnitude very near to the actual limit value of 6.0 1012 #/km. With the GPF's with better filtration quality, it is possible to lower the emissions below the future limit value of 6.0 1011 #/km.There is no visible nuclei mode and the ultrafine particle concentrations below 10mm are insignificant.Some of the vehicles show at constant speed operation a periodical fluctuation of the NP-emissions, as an effect of the electronic control
