Publication number: 20040128982Abstract: A diesel powered vehicle is provided with an SCR system which uses an external reducing reagent to convert NOx emissions in a manner which accounts for the effects of NOx transient emissions on the reducing catalyst. Actual NOx emissions produced by the engine are filtered using a variable NOx time constant in turn correlated to the reductant/NOx storage capacity of the reducing catalyst at its current temperature to account for changes in the SCR system attributed to NOx transient emissions. Catalyst temperature is filtered using a variable catalyst time, constant corresponding to current space velocity of the exhaust gas to account for changes in the catalyst temperature attributed to NOx transient emissions. The reductant is metered on the basis of the filtered, corrected NOx concentration applied at a NSR ratio based, in turn, on the filtered, corrected reducing catalyst temperature.Type: ApplicationFiled: December 17, 2003Publication date: July 8, 2004Applicant: Engelhard CorporationInventors: Joseph A.

Publication number: 20040128987Abstract: An electronic control unit (an ECU) detects an operating condition of an engine and quantity of particulate matters accumulated in a diesel particulate filter (a DPF) having an oxidation catalyst from a pressure difference across the DPF. The ECU operates temperature increasing means for regenerating the DPF based on the above detection results. During a low speed and light load operation, the ECU does not perform temperature increasing operation similar to an operation performed during a middle load operation. Instead, the ECU performs operation such as reduction of recirculated exhaust gas quantity in order to inhibit an increase in the quantity of the accumulated particulate matters. When the operating condition is changed afterward, the temperature increasing means is operated, so safe regeneration of the DPF is achieved.Type: ApplicationFiled: November 28, 2003Publication date: July 8, 2004Applicant: DENSO CORPORATIONInventors: Tsukasa Kuboshima, Masumi Kinugawa, Kiyonori Sekiguchi, Makoto Saito, Shigeto Yahata

Publication number: 20040129018Abstract: The subject invention pertains to a method and apparatus for cooling. In a specific embodiment, the subject invention relates to a lightweight, compact, reliable, and efficient cooling system. The subject system can provide heat stress relief to individuals operating under, for example, hazardous conditions, or in elevated temperatures, while wearing protective clothing. The subject invention also relates to a condenser for transferring heat from a refrigerant to an external fluid in thermal contact with the condenser. The subject condenser can have a heat transfer surface and can be designed for an external fluid, such as air, to flow across the heat transfer surface and allow the transfer of heat from heat transfer surface to the external fluid. In a specific embodiment, the flow of the external fluid is parallel to the heat transfer surface.Type: ApplicationFiled: July 22, 2003Publication date: July 8, 2004Inventors: Daniel P.

Publication number: 20040129021Abstract: A process for rectificatively separating fluids comprising (meth)acrylic monomers in a rectification column by directly cooling the vapor comprising (meth)acrylic monomers rising to the top of the rectification column to form top condensate comprising (meth)acrylic monomers, the condensation space at the top of the column being separated from the region of the rectification column containing the separating internals only by at least one chimney tray from which the top condensate formed is removed from the rectification column, which comprises effecting the direct cooling of the vapor in the condensation space in at least two spray zones which are spatially successive and are flowed through by vapor by spraying supercooled top condensate comprising added polymerization inhibitor, and the temperature of the sprayed supercooled top condensate becoming lower from spray zone to spray zone in the flow direction of the vapor.Type: ApplicationFiled: September 10, 2003Publication date: July 8, 2004Applicant: BASF AkiengesellschaftInventors: Joachim Thiel, Albrecht Dams, Jurgen Schroder

Publication number: 20040129024Abstract: The invention relates to a method and a device for reducing the adhesion tendency during the hot forming of a glass body, using at least two moulds, which are positioned on either side of the glass body and are brought into contact with the glass body at a temperature, at which the glass is deformable, whereby the moulds are configured with electrically conductive surfaces. The disadvantage of existing methods and devices is that the moulds have a tendency to adhere to the glass body to be formed and that the surface quality of the glass is impaired. The invention therefore discloses a method, according to which the conductive surfaces of the moulds that come into contact with the glass body are supplied with an alternating current. The device for carrying out said method has electrically conductive mould surfaces, which are connected to an alternating current source. This guarantees that a larger processing window is available as a result of the reduced adhesion tendency, i.e.Type: ApplicationFiled: October 7, 2003Publication date: July 8, 2004Inventors: Ulrike Stoehr, Olaf Claussen, Daniela Seiler, Sylvia Biedenbender, Gernot Roeth, Ralf-Dieter Werner

Publication number: 20040129026Abstract: In order to avoid deposition of evaporating alkali compounds on an inner surface of a hollow glass body during thermal processing to form a glass container from the hollow glass body, an overpressure is provided in the hollow glass body during the thermal processing. Either rinsing the hollow glass body with a gas, such as air, or at least partially closing the glass body at one end so that sufficiently rapid pressure equilibration is avoided, can provide this overpressure. The glass containers made by these methods are especially suited for food or pharmaceuticals because they have a reduced alkali release from their inner surfaces, for example at most about 2.0 mg/l sodium oxide.Type: ApplicationFiled: July 23, 2003Publication date: July 8, 2004Inventor: Reiner Bartsch
