  • GAS TURBINE ENGINE
    Publication number: 20190234239
    Abstract: In a gas turbine engine, a third bearing having a squeeze film damper is disposed between an outer periphery of an intermediate part in an axial direction of a low pressure system shaft and an inner periphery of an intermediate part in an axial direction a high pressure system shaft. Not only is it possible, by connecting the respective intermediate parts in the axial direction of the low and high pressure system shafts to each other via the third bearing to thus enhance bending stiffness of the low and high pressure system shafts and suppress centrifugal whirling, to prevent vibration from occurring, but it is also possible to suppress transmission of vibration between the low and high pressure system shafts by the squeeze film damper of the third bearing, thereby minimizing transmission of vibration to a casing.

  • EXHAUST AFTERTREATMENT SYSTEM AND DOC NO2 GENERATION ON-BOARD DIAGNOSTICS METHOD
    Publication number: 20190234278
    Abstract: A method for exhaust aftertreatment includes determining a diagnostic condition with respect to a threshold diagnostic condition, determining an SCR efficiency as a ratio of a readout of a first NOx sensor at a first NOx sensing position with respect to a readout of a second NOx sensor at a second NOx sensing position, the first NOx sensing position located about an engine out area within an exhaust stream before a DOC and the second NOx sensing position located about an output of an SCR device within the exhaust stream; and comparing the SCR efficiency to a threshold SCR efficiency range. If the SCR efficiency is less than the threshold SCR efficiency range, then trigger DOC failure for NO oxidation, and if the SCR efficiency is greater than or equal to the threshold SCR efficiency range, then DOC is determined to be operating within specifications.
