This study analyzed the impact of low temperature and increased vehicle weight on greenhouse gas emissions from internal combustion engine vehicles and hybrid vehicles. CO2 was the most emitted gas across all vehicle types and was more significantly affected by temperature changes. Under low-temperature conditions, hybrid vehicles showed the highest increase in CO2 emissions, while increased weight had a greater effect on diesel vehicles. CH4 and N2O emissions were mainly observed in diesel vehicles, with fuel type having a greater influence than external conditions. HWFET mode, the increase in CO2 emissions was similar across vehicle types, and the trends of CH4 and N2O were comparable to those in FTP-75 mode. Overall, temperature variation had a more substantial impact on exhaust emissions. |
