Abstract: The particulate filter, which collects emissions by filtering vehicle exhaust, is an effective technological measure for automobile oems to cope with increasingly stringent emission standards. Although this technology can effectively reduce pollutant emissions, its regeneration process is prone to side effects such as increased fuel consumption. Through the testing and project control of the regeneration process of gasoline particulate filter (GPF), the paper forms the test specification and evaluation index of the regeneration performance of GPF, which improves the maturity of vehicle project management and user satisfaction. It also accumulates valuable experience for the future to cope with the emission requirements of the new national standard.
