Analysis of Drivability Influence on Tailpipe Emissions by Means of Engine-in-the-Loop Test Benches
Due to increasing environmental awareness, standards for pollutant and CO2 emission legislations are getting stricter in most markets around the world. In important markets such as Europe, also the emissions during driving on real roads, the so called “Real Driving Emissions” (RDE), are now a part of the type approval process for passenger cars. In addition to the hybridization and electrification of vehicles, the complexity and degrees of freedom of conventional powertrains with internal combustion engines are continuing to increase in order to comply with stricter exhaust emission standards. Besides the different requirements placed on vehicle emissions, the drivability capabilities of passenger vehicles desired by the costumers, varies within markets.
