The present invention relates to an alumina fiber having the content of sodium oxide of 530 to 3,200 ppm and a mass ratio (A/B) of the content (A) of the sodium oxide to the content (B) of calcium oxide of 5 to 116.

The present invention relates to a metal oxide coated composite comprising a core consisting of a mixture of a La stabilized Al.sub.2O.sub.3 phase and an Ce/Zr/RE.sub.2O.sub.3 mixed oxide phase, the core having a specific crystallinity, specific pore volume and a specific pore size distribution, and a method for the production of the metal oxide coated composite.

A substantially metal-free exhaust subsystem includes an exterior housing formed of polymer; and a pipe formed of a layered fibers formed at least partially of glass, and bound by an inorganic binder. The fibers may be glass or ceramic, and may define micro-pores on the interior of the pipe that aid in absorbing acoustic energy, and thereby attenuating exhaust noise.

A tubing to supply diesel exhaust fluid to an exhaust system of a diesel engine includes an inner layer made of a first material and an outer layer made of a second material. The first material includes polyethersulfone polymer or polyphenylene sulfide. The second material includes a polyamide or polyphthalamide. An outer surface of the inner layer and an inner surface of the outer layer include a reactive material that facilitates bonding between the inner layer and the outer layer of the tubing.

The disclosure relates to an electrical connector comprising an electrical conductor, an electrical insulator surrounding the electrical conductor, and a housing surrounding the electrical insulator. A ring surrounds the electrical insulator, and is arranged in an extension of the housing, longitudinally at an end of the electrical insulator and longitudinally spaced from the housing by a length at least equal to one times a thickness of the electrical insulator.

A diesel engine emissions catalyst which may be used to fill a niche between standard oxidation catalyst and diesel particulate filters for control of diesel particulate matter. The catalyst includes a structure (substrate) comprising one or more coated, corrugated micro-expanded metal foil layers. The coated surface may be a high surface area, stabilized, and promoted washcoat layer. The corrugated pattern may include a herringbone-style pattern that, when in use, is oriented in a longitudinal direction of the diesel engine exhaust flow. The micro-expanded metal foil provides small openings or eyes that, as the exhaust flow passes through the catalyst (transverse to the eye opening), particulates in the flow impinge on the surface and becomes trapped in the eyes. The catalyst may be used to treat a locomotive engine exhaust stream and may be used with a selective catalyst reduction system.

An exhaust gas treatment system (1) comprises a catalyst article (5) for the treatment of an exhaust gas, the catalyst article (5) comprising a non-metallic substrate (20) comprising a plurality of catalytically-active transition-metal-doped iron oxide magnetic particles (45), and an inductive heater (70) for inductively heating the plurality of catalytically-active magnetic particles by applying an alternating magnetic field.
