Real Driving Emissions in Extended Driving Conditions

The real driving emission (RDE) testing for certification of vehicles is performed in conditions that are well defined legislation. For emissions inventories and research, the influences some extended on an interesting issue. In present work, examples RDE results from two common passenger cars with gasoline diesel propulsion given. varying were “winter/summer”, “mild/aggressive”, “higher altitude/slop”. conditions: “winter”, “aggressive”, slope/altitude” generally require more energy, cause higher fuel consumption, therefore, CO2-emissions. condition “winter driving”, especially urban type operation, may longer phases not enough warmed-up exhaust aftertreatment consequently increased gaseous emissions. DPF eliminates nanoparticles (PN) independently conditions. Nevertheless, regeneration has influence CO2-normality trip. primary tolerance range can also be exceeded aggressive driving. elaborated confirm usefulness existing legal limits homologation tests.
