Abstract
AbstractChina 6 regulation “GB18352.6-2016 limits and measurement methods for emissions from light-duty vehicles” has imported standard RDE test of Europe Union. Impacted by driving style and real road condition, RDE has characteristics as its boundary uneasy to control and bad reproduction. So it is very difficult to realize accurate calibration on real test road. This article aims at analyzing RDE test method indoors. DFTC-RDE test conditions for roller bench usage are built on the basis of the chosen RDE test conditions data of real vehicle and WLTC cycle test results on the roller bench. The results show that this DFTC-RDE roller bench test condition can be used in engine tasks in different powertrain adaptation on vehicle with a coverage of 90%. Instantaneous emission of DFTC-RDE roller bench test condition equals to that of WLTC test condition. It can represent RDE test condition instantaneous emission. Via calibration optimization, DFTC-RDE test condition can be applied to RDE emission test.KeywordsReal driving emission (RDE)Indoors DFTC-RDE test conditionContaminant emissionEngine work area
