Analysis and Modeling of Real Driving Emissions (RDE)
Sprache des Titels:
Real driving emissions (RDE) are gaining attention due to the deviation of legal limitations
and combustion engine vehicles? exhaust pipe emissions. Especially nitrogen oxides? boundary values are exceeded by many modern diesel cars. Upcoming legislative changes concerning the admission procedure of light-duty vehicles necessitates closer investigation of actual on-road exhaust pipe emissions. The state-of-the-art approach for pollutants assessment involves test
bench measurements for representative driving cycles and a transfer of obtained emission data
to real cars. Thus, vehicle manufacturers design engines in order to meet the requirements of
test cycles rather than for the real application, which leads to an embellishment of officially declared emission levels. The transferability of test bench measurements is questionable and hence examined by comparing them with RDE data.
