Abstract: This article first explains the reasons for the deterioration of the particulate trap, and then qualitatively analyzes and summarizes the main influencing factors of active regeneration. On this basis, the gray correlation model is used to determine the influence of several influencing factors on the regeneration efficiency. The influence degree is sorted, which can provide a certain reference basis for the optimization of the regeneration performance of the particulate trap.
