Abstract
As the China VI emission regulation for light duty passenger car is officially released, WLTC will take place of NEDC to be the standard cycle for type approval. This paper is based on a series of tests carried out in Dongfeng Motor Corporation Technical Center on a DFMC. China V vehicle with a turbo-charged PFI gasoline engine shows that no significant difference between NEDC and WLTC regarding to THC, NOx and NMHC emissions, while a big influence on the CO emission can be tested. By optimizing the calibration and gear shifting pattern, CO emission can be reduced to the limit of China VI regulation.
