摘要:
An exhaust particulate filter for an engine system includes an array of filter cartridges positioned within a shell, each of the cartridges having an electrically powered heating element coupled therewith. Exhaust gases are distributed among the cartridges according to a single distribution pattern, and the filter can be regenerated without diverting, dividing or bypassing exhaust gases from the filter. Other aspects include feedback control and feedforward control of regeneration based on sensing an electrical resistance property of each of the electrically powered heating elements.

An exhaust particulate filter for an engine system includes an array of filter cartridges positioned within a shell, each of the cartridges having an electrically powered heating element coupled therewith. Exhaust gases may be distributed among the cartridges according to a single distribution pattern, and the filter can be regenerated without diverting, dividing or bypassing exhaust gases from the filter. The filter cartridges may be cylindrical or wedge-shaped, or of a variety of other configurations. Regeneration may take place according to a non-axial regeneration propagation profile. Other aspects include feedback control and feedforward control of regeneration based on sensing an electrical resistance property of each of the electrically powered heating elements.
摘要:
An exhaust particulate filter for an engine system includes a housing having an inlet, an outlet and a shell shaped to fit the particulate filter within a predefined spatial envelope. Filter elements arranged in a bundle and having a packing arrangement are positioned within the housing. Each of the filter elements includes a perforated tube wrapped with fibrous metallic filter media. The bundle defines a perimetric line at least partially matched to the shape of the shell. An assembly method for a particulate filter includes arranging filter elements in a packing structure within a bundle, the bundle having peripherally located filter elements and internally located filter elements. The filter elements each include a perforated tube wrapped with fibrous metallic filter media. The assembly method further includes positioning the bundle of filter elements within a housing having a shape at least partially matched to a shape of the bundle. A unique method of joining various of the components via swagging is also disclosed. Clamping of the filter media, and joints between filter element and support plates, may be achieved via swagging, for example.

An electrical connection element for providing an electrical connection to a porous material may include a first electrically conductive plate disposed on at least a portion of a first side of the porous material. A second electrically conductive plate may be disposed on at least a portion of a second side of the porous material, opposite to the first side. An electrically conductive material may impregnate the porous material in a region between the first and second electrically conductive plates, and an electrical connector may be attached to at least one of the first and second electrically conductive plates.

An exhaust particulate filter for an engine system includes a housing having an inlet, an outlet and a shell shaped to fit the particulate filter within a predefined spatial envelope. Filter elements are arranged in a composite filter assembly and are packed within a housing. Each of the filter elements includes a cartridge having a frame wrapped with fibrous metallic filter media. The composite filter assembly has a shape corresponding to the shape of the shell. Each cartridge of the composite filter assembly is reversibly coupled with a frame internal of the shell via trapping elements having a release state and a trapping state.
摘要:
A particulate filter includes a filter element comprising a non-perforated tube having an exhaust inlet at a first end and an exhaust outlet at a second end. A fibrous metallic filter medium is disposed within the filter element and is configured to trap particulate matter from an exhaust gas. A first metallic foam disk is attached at the second end of the filter element, and retains the fibrous metallic filter medium within the filter element. A second metallic foam disk may be attached at the first end of the filter element and may allow the particulate filter to be reversed with respect to an exhaust gas flow.

A camshaft used in an internal combustion engine which has reduced weight and added wear resistance at a lobe of the camshaft. The camshaft is provided to add increased wear resistance and reduced weight to the internal combustion engine for increased efficiency of the internal combustion engine. The camshaft includes wear resistant material at the surface of the lobe of the camshaft. The wear resistant material is distributed on the outer surface of the lobe and incorporated into the base material.
