Exhaust gases are no longer the most important emission factor from motor vehicles by far when it comes to particulate matter. This is shown by a large-scale study carried out by Graz University of Technology (TU Graz) for the FVV eV.in Germany, in which the non-exhaust emissions for the current European car fleet were also recorded. The findings are published as part of the SAE Technical Paper Series.
