  • Patent number: 10018089
    Abstract: A diesel particulate filter system comprising: a temperature sensor on the inlet side of the diesel particulate filter; a temperature sensor on the outlet side of the diesel particulate filter; a pressure sensor on the inlet side of the diesel particulate filter; and a control module in communication with the temperature sensors and the pressure sensor, and the control module is loaded with a look-up table that correlates the amount of soot loaded in the diesel particulate filter to a change in pressure measured by the pressure sensor; wherein the control module Initiates a regeneration cycle when soot loading of the diesel particulate filter achieves a predetermined soot load.

  • Publication number: 20150121827
    Abstract: A ceramic plugging paste useful to make plugs having through holes (partial plugs) in a ceramic honeycomb filter in which the plugging paste is comprised of a ceramic particulate and fluid carrier, wherein the ceramic particulate has at least 90% by number of the particulates being less than 50 micrometers and the fluid carrier is present in an amount sufficient such that the plugging paste is fluid enough to be inserted into a ceramic honeycomb channel and be retained in said channel without any other support other than the walls of the honeycomb defining the channel. Such a paste may be easily injected in the same manner as regular pastes. Such pastes and methods advantageously realize plugs having a through hole resulting in honeycomb filters having low pressure drop while still retaining effective particulate filtration.

  • Patent number: 8999448
    Abstract: Organic polymer particles are provided in a cement composition that is used to apply a skin to a ceramic honeycomb, or to bond the ceramic honeycomb to another honeycomb or another material. The presence of the organic polymer particles reduces the penetration of the cement composition through porous walls of the honeycomb. In this way, less blocking of the honeycomb cells is seen, and the reduction in thermal shock performance that is often seen when cement compositions are applied to ceramic honeycombs is reduced.

  • Publication number: 20150040763
    Abstract: Ceramic honeycomb assemblies are made from ceramic honeycomb sections arranged sequentially in an axial direction. The plugging patterns of the cells in the various sections are varied so that a portion of a fluid entering the assemblies can pass through upstream section(s) of the assembly without being filtered. One or more downstream sections capture particulate matter that has passed through the upstream sections without being filtered. This design reduces “ring-off” cracking, and high filtration capacity, with little increase in pressure drop during operation.

  • Publication number: 20140199482
    Abstract: Skins and/or adhesive layers are formed on a porous ceramic honeycomb by applying a layer of a cement composition to a surface of the honeycomb and firing the cement composition. The cement composition contains inorganic filler particles, a carrier fluid and a clay material rather than the colloidal alumina and/or silica materials that are conventionally used in such cements. The cement compositions resist permeation into the porous walls of the ceramic honeycomb. As a result, lower temperature gradients are seen in the honeycomb structure during rapid temperature changes, which results in an increased thermal shock resistance.

  • Patent number: 7560003
    Abstract: The present invention includes devices and methods of forming a structural component of a transportation vehicle and preferably an automotive vehicle. The invention includes a hybrid structure, preferably formed of two or more components that are bonded together with an adhesive to form a structural component that is lighter in weight than that of traditional components formed out of metal. The hybrid component is also substantially free of an over-molding process. Advantageously, one or more snap-fits or the like may be used to position and maintain spatial relationship of the two or more components during assembly, and compression and curing of the adhesive.
