    Abstract: An engine exhaust filter system comprises a housing and a pleated filter element. The housing includes an inlet and an outlet and defines an exhaust flow path between the inlet and the outlet. The pleated filter element is disposed in the exhaust gas flow path between the inlet and the outlet. The pleated filter element includes a filter medium and at least a first perforated support member, the filter medium being disposed adjacent to the perforated filter support member. The filter medium includes a portion extending beyond the perforated support member comprising a seal that prevents or reduces bypass of unfiltered exhaust gas around the pleated filter element.

    Abstract: A diesel engine exhaust particulate filter-incinerator comprising an enclosed filter panel having particulate deposition surfaces bordered by electrodes of a high voltage power supply. Periodic incineration is accomplished by the collection on the surfaces of particulates in amounts sufficient to conduct sufficient electric current along paths through the particulates to heat them to incineration temperature. Ignition and burn off of particulates may be automatically accomplished by maintaining a suitable voltage across the electrodes at the edges of the collection surfaces to initiate arc-like current flow before the collected particulates reach a level that would plug the filter. Specific embodiments of exemplary filter constructions are disclosed.

    Abstract translation: 一种柴油发动机废气微粒过滤器焚烧炉，其包括具有由高压电源的电极界定的颗粒沉积表面的封闭过滤板。 周期性焚烧是通过在微粒表面上收集的量来完成的，其量足以沿着通过微粒的路径传导足够的电流以将它们加热到焚化温度。 可以通过在收集表面的边缘处的电极两端保持合适的电压来自动实现点火和燃烧，以在所收集的微粒达到堵塞过滤器的水平之前启动电弧状电流。 公开了示例性过滤器结构的具体实施例。

    Abstract: A pollutant filtering assembly for filtering pollutants from vehicle exhaust includes a tube that has a diameter which is sufficient to facilitate the tube to be inserted into an exhaust pipe of a vehicle. A sleeve extends around the tube to facilitate the exhaust pipe to extend between the tube and the sleeve. A handle is pivotally coupled to the tube for inserting the tube into the exhaust pipe. A filtering cartridge is insertable into the tube. Each filtering element of a plurality of filtering elements of the filtering cartridge is made of a unique pollutant filtering material with respect to each other. Moreover, each of the filtering elements can filter pollutants from exhaust of the vehicle.
