Abstract

Reducing vehicle emissions and minimizing the impact of the transportation industry on the environment are key to achieving global sustainable development goals. China-6 emissions standard requires light-duty gasoline vehicles to meet the emissions limit requirements for particulate number (PN) emissions. Therefore, light-duty gasoline vehicles must also be equipped with a gasoline particulate filter (GPF) in addition to the three-way catalytic converter (TWC) and meet the emissions limit requirements within a durability mileage of 200,000 km. Currently, there is very little research on the impact of GPF degradation on the fuel economy and emissions of gasoline vehicles, especially on the newly restricted N 2 O emissions. This study adopts the vehicle test method to study the deterioration of emissions of a China-6 light-duty gasoline vehicle with driving mileage. The research results show that the emissions of gasoline vehicles still meet the emissions limit after driving 200,000 km, and the deterioration factors of various emission pollutants are less than the recommended deterioration factors. The gasoline vehicle’s carbon dioxide (CO 2 ) emission and fuel consumption increase by less than 3%, indicating that the aging of vehicle components, including TWC and GPF, has no significant impact on vehicle fuel economy.
