    摘要: A method and means for controlling diesel particulate emissions involves providing an exhaust trap filter to collect exhaust particulates at a point near the engine exhaust ports and providing means to periodically vent burning combustion chamber gases to the exhaust filter to initiate combustion and incineration of the collected particulates. Various means for conducting burning mixture to ignite the particulates in the filter are disclosed.

    摘要: An arrangement of dual element alternate flow exhaust cleaner and burner device for diesel engines is disclosed which provides trapping of particulates in the engine exhaust gases by their passage through either of the two elements. Collected particulates of carbon and other combustibles in the other nonactive element are electively incinerated by excess air or oxygen containing gas heated by a suitable burner or heater device. The incinerated products from the inactive element are redirected into the exhaust stream to pass through the active element for the cleansing of particulates remaining from the burnoff process before discharge.

    摘要: A diesel exhaust cleaner and regeneration system with indexing particulate trap for use with a diesel engine, as on a city bus, includes a housing means having a cylindrical intermediate housing, an exhaust inlet means at one end and an exhaust outlet at its opposite end with a shaft operatively journaled in the intermediate housing for rotation about the axis thereof and having one end thereof extending outboard of said exhaust inlet means to permit exterior rotation thereof. A cylindrical trap housing means is fixed to the shaft whereby it is sealingly and rotatably supported in the intermediate housing, the trap housing means including a plurality of circumferentially spaced apart filter supports located concentrically around the shaft with a particulate filter operatively supported in each of the filter supports. A fuel burner means is operatively fixed to the exhaust inlet means with the outlet end of the burner means located in operative axial alignment with one of the filters. A releasable detent means is operatively associated with the intermediate housing and with the trap housing means to permit rotative indexing of the particulate filters sequentially into operative alignment with the fuel burner means upon rotative movement of the shaft so that all of the filters can be sequentially regenerated.

    摘要: A diesel exhaust particulate trap is provided with a heat resistant particulate filter which includes a perforated and pleated metal substrate member coated with a ceramic fiber filter material on its interior surface so as to define a filter chamber for the inside-out flow of exhaust gases through the filter. In a preferred embodiment, an electrical particulate filter igniter is associated with the filter. The igniter includes a trap door pivotably secured to the substrate member, which is normally biased to a closed position by a spring but which can be opened by exhaust flow prior to an accumulation of particulates on the filter. Opening and closing of the trap door is used to effect deenergization and energization, respectively, of an electrical heating element used to initiate combustion of particulates.

    摘要: A wall flow monolith, for example, of circular configuration has its outer surface at the inlet end cut on tangents so as to provide four chordal flat surfaces with at least alternate channels next to these surfaces plugged at the inlet end so that exhaust flow is through these chordal surfaces into these channels whereby particulates are collected on the chordal surface. Glow plugs are positioned to ignite particulates on these chordal surfaces and, these glow plugs are energized either individually or in sets as an accumulated time function of engine operation.

    摘要: An exhaust cleaner system for use in the exhaust system of a diesel engine is provided with a particulate filter positioned in a trap housing with an exhaust inlet thereto and an exhaust outlet therefrom. A pair of exhaust ducts are positioned in the inlet end of the exhaust outlet whereby to define, in effect, three separate exhaust flow zones through the filter and a flow limiter valve is operatively positioned to sequentially control flow through the exhaust ducts. Glow plugs are located so as to extend into the zones of the filter associated with the exhaust ducts to initiate incineration of particulates during reduced exhaust flow conditions as controlled by the flow limiter valve.
