Abstract: European regulations set upper limits on the emission of some exhaust pollutants of passenger cars. These pollutants are called regulated pollutants (RP) and are CO, HC and NOx in the case of gasoline passenger cars and CO, HC, NOx and particulate matter (PM) in the case of Diesel ones. Those upper limits change every 3-5 years and the current ones are much lower than those of the initial regulations. However, passenger cars emit several other pollutants which are not regulated (non-regulated pollutants, NRP). These pollutants are emitted in much lower concentrations than the regulated ones; however, they are sometimes much more dangerous for the environment or the human health. This work shows the emissions of several non-regulated pollutants of gasoline and Diesel passenger cars. The impact of technology, which are related with the emission level of regulated pollutants, and of mileage are presented and discussed.
