Engine exhaust particulate trap
By using a magnetic drive structure to rotate the filter cleaning unit and remove retained particulate matter, the problem of clogging of engine exhaust particulate filters during long-distance or congested driving is solved, achieving efficient filtration and circulation of exhaust gas and avoiding exhaust gas leakage and noise.

AI Technical Summary
Existing engine exhaust particulate filters are difficult to trigger the regeneration process when driving on long-distance short trips or in congested roads, causing particulate matter to accumulate and clog the filter holes, affecting exhaust gas flow efficiency and normal engine operation. At the same time, the mechanical transmission structure is prone to exhaust gas leakage and noise.
It adopts a non-contact magnetic transmission structure. Through the magnetic transmission cooperation between the outer magnetic drive ring and the inner magnetic linkage seat, the filter cleaning kit is driven to rotate and clean the retained particles, avoiding exhaust gas leakage and noise, and ensuring exhaust gas filtration and circulation efficiency.
It achieves the cleaning of retained particulate matter under sealed conditions, prevents filter pore blockage, reduces exhaust back pressure, ensures normal engine operation, and avoids exhaust pollution and noise problems.
