US Classification:

4232391, 4232135, 502302, 502303, 502304, 502326, 502334, 502339

Abstract:

The present invention relates to a layered catalyst composite of the type generally referred to as a three-way conversion catalyst having the capability of simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides. The structure of the layered catalyst composite of the present invention is designed wherein there are three layers in conjunction with a carrier: a first layer deposited on the carrier and comprising a high surface area refractory metal oxide; a second layer deposited on the first layer and comprising palladium and/or platinum deposited on a high surface area refractory metal oxide, and having substantially no oxygen storage components; and a third layer deposited on the second layer and comprising platinum and/or rhodium as well as an oxygen storage component, deposited on a high surface area refractory metal oxide.

International Classification:

B01D 50/00

US Classification:

422180

Abstract:

Provided is an exhaust article (catalyst) coated on a single substrate, such as a monolithic honeycomb having a plurality of channels along the axial length of the catalyst. Different washcoat compositions are deposited along the length the channel walls of the substrate beginning from either the inlet or outlet axial end of the substrate to form inlet and outlet catalyst layers, respectively. In the coating process, the channel walls are coated with catalyst washcoat compositions to lengths that are less than the substrates' axial length. The architecture of the resulting catalyst layers defines a plurality of zones along the length of the substrate. The properties of each zone of the catalyst can be optimized to address specific catalyst functions by manipulation of both the coating lengths and the catalyst washcoat compositions.

International Classification:

B01D 50/00

US Classification:

422180

Abstract:

The invention provides a catalyzed soot filter formed on a wall flow substrate having internal walls coated with catalyst compositions. The soot filter maintains a homogeneous flow of the exhaust gases through the internal walls of the substrate along the length of the filter due to the coating design. Both the efficiency and the durability of the catalytic function are increased over conventionally designed catalyzed soot filters. The catalyzed soot filter provides an integrated function for simultaneously treating the gaseous components of the exhaust (e. g. , CO and HC) and the particulate matter deposited in the filter.

Abstract:

Materials of the general formula MXY. sub. 3 wherein M is selected from the group consisting of Mg, V, Mn, Fe, Co, Ni, Zn, Cd, Sn, Pb and mixtures thereof; X is a pnictide selected from the group consisting of phosphorus, arsenic, antimony, and mixtures thereof, and Y is a chalcogenide selected from the group consisting of sulfur, selenium and mixtures thereof, have been discovered to be superior lubricants exhibiting resistance to oxidation and thermal degradation, low friction, excellent antiwear activity and long effective life. Metal surfaces coated with such materials resist gauling and damage due to adhesive or corrosive wear. These materials can be used as dry solid lubricants or as additives to oils and greases.

International Classification:

B01J 2310

US Classification:

4232135

Abstract:

A catalytic material effective for the reduction of NO. sub. x and the oxidation of at least carbon monoxide includes an oxygen storage component that provides superior oxygen storage function. The oxygen storage component includes an intimately combined mixed oxides including cerium, neodymium and zirconium. Typically, the ceria constitutes more than about 30 percent by weight of the ceria plus zirconia in the intimately combined mixed oxide, e. g. , from about 32 to 44 weight percent. Preferably, the intimately combined mixed oxide also includes up to about 26 percent neodymia by weight of the ceria, e. g. , from 18. 6 to 23. 5 percent. The intimately combined mixed oxide may be a co-formed material that may be prepared by, e. g. , co-precipitating compounds of zirconium and the rare earth metal and calcining the co-precipitate.

International Classification:

F02M 2508

US Classification:

123520

Abstract:

A pre-vaporized fuel system for use in fueling an internal combustion engine is provided with a dynamic infrared sensor. The infrared sensor senses the hydrocarbon content of the vaporized fuel which information is used by the engine control module to control engine fueling to minimize emissions. The infrared source is operated to maintain the pre-vaporized fuel below its lower explosive limit and the thermopile detector electronics is synchronized with the light pulse frequency to develop fast signal responses suitable for fueling control.
