    Abstract: A method for production of an exhaust-gas routing device that has a housing, an elongated substrate, and a compensating element, includes the following steps. At least one parameter of the substrate and/or of the compensating element is determined A target parameter, which describes a variable linked to a target geometry of the housing, is determined based on the measured parameter of the substrate and/or of the compensating element. The substrate and the compensating element are arranged in the housing, and the housing is deformed with an overpressure factor which is determined on the basis of at least one previous deformation of a previously manufactured device. The housing is measured after the deformation, and the thus-established values are compared with the target parameter. An overpressure factor for the deformation of a subsequently manufactured device is adapted if a deviation from the target parameter is detected upon measuring which lies above a defined threshold value.

    Abstract: An electrically heated catalyst device includes a catalyst support including a ceramics, on which a catalyst is supported, a pair of surface electrodes disposed on an outer surface of the catalyst support, the surface electrodes being disposed opposite to each other and extending in an axial direction of the catalyst support, and a wiring line that externally supplies electric power to the surface electrodes, in which the catalyst support is electrically heated through the surface electrodes. A wrought member made of metal is buried in the surface electrodes, the wrought member extending in the axial direction of the catalyst support. With the configuration like this, the spreading of electric currents in the catalyst-support axis direction can be maintained even when cracks occur in the catalyst-support circumference direction in the surface electrodes.

  • Publication number: 20140294678
    Abstract: An exhaust emission purification control device for an engine that accurately estimates an accumulated oxygen amount of a catalyst at a terminating time of a reduction treatment using a simple method. An exhaust emission purification control device for an engine includes a secondary air injector that injects secondary air within an exhaust path. An O2 sensor detects an air-fuel ratio in a downstream side of a catalyst. A count-value accumulator estimates an accumulated oxygen amount (a count value) in the catalyst during the secondary air injection. A rich spike controller performs rich injection after the secondary air injection. This device includes a count-value corrector that multiplies the count value after the secondary air injection by a correction coefficient derived from an output value SVO2 of the O2 sensor during termination of reduction treatment, so as to estimate the accumulated oxygen amount during the termination of the reduction treatment.

  • Publication number: 20140283528
    Abstract: To assemble an aftertreatment module for use in the treatment of exhaust gasses and the like, an aftertreatment brick is inserted into a sleeve opening in a sleeve and advanced toward an opposite end of the sleeve. To retain the aftertreatment brick in the sleeve, the end of the sleeve can include a stop flange and the aftertreatment brick can include a mantle flange. The stop flange and the mantle flange can abut against each other to prevent further movement of the aftertreatment brick through the sleeve. To seal against exhaust gasses leaking though the module, a gasket can be disposed between the stop flange and the mantle flange. Exterior ribs disposed around the aftertreatment brick can assist concentric alignment between the flanges and gasket.
