  • Publication number: 20100043363
    Abstract: Disclosed is an improved axial flow unitary filter element for filtering a fluid stream, examples including a gaseous or an air stream. The filter element includes a primary filter portion and a pre-separation filter portion. The portions of said filter element are permanently integrated such that the portions form said unitary or one-piece filter element. The pre-separation portion is permanently secured and fully peripherally sealed about its peripheral portions to the primary filter such that a gaseous stream entering said inlet face of the primary filter must first pass through the pre-separation filter portion of the filter element. The pre-separation portion protects the primary filter portion from becoming water logged due to the presence of water droplets or snow in the fluid stream.

    Abstract: There is provided an injector assembly having two or more oxidizer manifolds and/or two or more fuel manifolds for delivery of liquid propellants to a combustion chamber such that combustion instability is reduced or eliminated during throttling. Delivery of the oxidizer to the oxidizer manifolds is controlled by an oxidizer valve, which may comprise an integral valve. The oxidizer passes from the oxidizer manifolds into the oxidizer element and then into the combustion chamber. The multiple oxidizer manifolds allow the oxidizer to be provided through selective openings of the oxidizer element thus reducing the change in pressure drop across the oxidizer element to thereby reduce or eliminate combustion instability and other problems. Additionally, the injector assembly may also include a lift-off seal or a filler fluid source to fill any temporarily unused oxidizer manifolds with an oxidizer or filler fluid.

    Abstract: A turbofan engine (10) includes a fan variable area nozzle (FVAN) (50) which effectively changes the physical area and geometry within a fan bypass flow path (40) to manipulate the pressure ratio of the bypass flow. The FVAN generally includes a multitude of aerodynamically shaped inserts (52) circumferentially located about the core nacelle (12). The FVAN at a fully stowed position (takeoff/landing) takes up a minimum of area within the fan bypass flow path to effectively maximize the fan nozzle exit area (44) while in the fully deployed position (cruise) takes up a maximum of area within the bypass flow path to effectively minimize the fan nozzle exit area. By separately adjusting each of the multiple of inserts relative the other inserts the FVAN provides an asymmetrical fan nozzle exit area to selectively vector the fan bypass flow.

  • Publication number: 20100043400
    Abstract: A powertrain includes an internal combustion engine and an aftertreatment system having an aftertreatment device utilizing a catalyst to convert NOx. A method for indicating a malfunctioning catalyst includes monitoring an actual NOx content exiting the aftertreatment system, monitoring factors affecting conversion efficiency of the aftertreatment device, determining a predicted threshold NOx content exiting the aftertreatment system for an exemplary malfunctioning catalyst based upon the factors affecting conversion efficiency, comparing the actual NOx content exiting the aftertreatment system to the predicted threshold NOx content exiting the aftertreatment system, and indicating a malfunctioning catalyst based upon the comparing.

  • Publication number: 20100043401
    Abstract: A control method for an internal combustion engine including an exhaust gases post-processing system and a system for recirculating the exhaust gases towards the intake, wherein the engine can be switched from a regeneration operation mode with throttling to a nominal mode without throttling. At the end of the engine operation in the regeneration mode, the engine is temporarily operated in an intermediate mode with partial throttling for limiting the contrast of the intake noise.

  • Publication number: 20100043403
    Abstract: The invention has its object to automatically conduct forced regeneration of a particulate filter 6 even if a driver forgets to conduct a manual operation under operation conditions met for the manual operation. A controller 9 (deposition amount estimating means) is constructed such that fuel addition by a fuel injection device 10 (fuel addition means) is automatically conducted when a predetermined time has passed with the diesel engine 1 being in idling state and without a regeneration button 15 (operation means) being manually operated under condition of a particulate deposition amount being estimated by the controller 9 on the basis of a pressure signal 8a from a pressure sensor 8 (deposition amount estimating means) to be within a manual regeneration range over an automatic regeneration range.

  • Publication number: 20100043405
    Abstract: In an internal combustion engine, an NOX selective reducing catalyst is arranged in an engine exhaust passage. Urea is fed in the NOX selective reducing catalyst, ammonia generated from this urea is adsorbed at the NOX selective reducing catalyst, and the NOX contained in the exhaust gas is selectively reduced mainly by the adsorbed ammonia. An NOX sensor able to detect NOX and ammonia contained in the exhaust gas is arranged in the engine exhaust passage downstream of the NOX selective reducing catalyst. It is judged that the amount of adsorption of ammonia at the NOX selective reducing catalyst is saturated based on the detection value of the NOX sensor when the feed of fuel to the engine is stopped during the deceleration operation.

  • Publication number: 20100043408
    Abstract: The invention relates to a method for the calibration and/or management of an exhaust line of a motor vehicle comprising a particle filter (X), said method comprising an initial step of measuring, over a representative population of the filter, the increase in the loss of load generated by a limited load of soot particles present in a filter, that is the threshold for the triggering of a filter regeneration phase; a step of measuring, in the absence of soot particles, the loss of specific load of the filter (X); and a step of determining, on the basis of the values obtained in steps a) and b), a limited value for the loss of load, that is the threshold for the triggering of a regeneration phase. The invention also relates to a system for managing an exhaust line comprising means for implementing said method.

  • Publication number: 20100043410
    Abstract: An object of the present invention, in an internal combustion engine equipped with a moisture adsorbent and a NOx adsorbent in series in order from the upstream side of an exhaust passage, is to provide an exhaust gas purifying apparatus for the internal combustion engine which can successfully prevent an adsorption capability of NOx from being inhibited by moisture and is capable of maintaining the NOx adsorption capability of the NOx adsorbent adequately. A main exhaust passage 14 through which exhaust gas exhausted from an internal combustion engine 10 flows is provided. A bypass passage 20 bypassing the main exhaust passage 14 is provided. A moisture adsorbent 24 and a NOx adsorbent 28 are provided in the bypass passage 20 in series in order from a side closer to the upstream connecting portion 20a. A switching valve 22 is controlled to prevent the exhaust gas from flowing into the NOx adsorbent 28 when it is judged that the desorption of the moisture from the moisture adsorbent 24 is started.
