Ludecke, O A

This patent describes an indexing particulate filter trap and regeneration system for use with a diesel engine as on a city bus. This system includes a housing having a cylindrical intermediate housing, an exhaust inlet at one end and an exhaust outlet at its opposite end. A shaft is operatively journaled in the intermediate housing for rotation about the axis thereof and has one end thereof extending outboard of the exhaust inlet means to permit exterior rotation thereof. A cylindrical trap housing is fixed to the shaft. The trap housing includes circumferentially spaced apart filter supports located concentrically around the shaft. A particulate filter is operatively supported in each of the filter supports. A fuel burner is operatively fixed to the exhaust inlet means with the burner outlet end thereof in operative axial alignment with one of the filter supports. 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.
