The Real Driving Emission test (RDE) required in China 6 regulation (GB 18352.6-2016) followed the EU 6 regulation (EC 2016/646), where cold start is excluded in emission calculation. Since cold start is an important stage of pollutant formation, the European Union had developed further requirements for cold start in EU 6 regulation (EC 2017/1154 and EC 2018/1832), which created generation gaps between China 6 and EU 6 RDE test requirements. This work is based on real RDE tests on public road
