N2 - In order to improve the uneven flow of exhaust in traditional catalytic gasoline particulate filter system (C-GPFs) and improve the regeneration performances under low-temperature conditions, the new C-GPFs integrated regeneration model is established and explored. In this work, firstly, the NO catalytic rate and soot combustion rate are defined as the evaluation indicators of the new C-GPFs integrated regeneration performances. Secondly, based on the numerical simulation software, the regeneration performances of the new C-GPFs with and without electric heating are compared and analyzed, and the calculation model is verified based on the engine experiments. Then, the effects of four different structure parameters on the regeneration performances of the new C-GPFs are studied. Finally, through the orthogonal experiments, the influence weights of the four parameters on NO catalytic rate, soot combustion rate, and pressure drop are explored, and the new C-GPFs are optimized under simulation conditions. The results show that after optimization, the NO catalytic rate is enhanced by 2.1%, the soot combustion rate is enhanced by 11.9%, and the pressure drop is increased by 3%. This work provides an important reference value for improving the integrated regeneration performance of the C-GPFs in a gasoline engine.
