description | China implemented the China VI emission standard in 2020. The China VI emission standard has added requirements for the RDE (real-world driving emission) test. To evaluate vehicle CO<sub>2</sub> emission for different vehicles, 10 conventional gasoline vehicles were tested under the RDE procedure using the PEMS (portable emission testing system) method. All vehicles tested meet the sixth emission regulation with a displacement of 1.4 L~2.0 L. Among the vehicles tested, the highest CO<sub>2</sub> emission factor was 281 g/km and the lowest was 189 g/km, while the acceleration of RDE gets a wider distribution, varying from −2.5 m/s<sup>2</sup> to 2.5 m/s<sup>2</sup>. The instantaneous mass emission rate could reach around 16 g/s. The amounts of total CO<sub>2</sub> emission in the positive region and the negative region make up 82~89% and 11~18% of the overall CO<sub>2</sub> emission during the entire RDE driving period, respectively. The same vehicle has a wide range of CO<sub>2</sub> emission factors at different VSP (vehicle specific power) intervals. Different RDE test conditions can lead to large differences in CO<sub>2</sub> emissions. |
