  • Patent number: 11858330
    Abstract: In an electrified vehicle, such as a battery electric vehicle, those with a hybrid powertrain, range extended electric vehicles, or hydrogen powered vehicles, integration of the battery may mean that space is very constrained. Typically this means that there is no feasible method to lift the battery to disengage it from the vehicle or to operate any engagement catches or locks etc. The disclosure provides a roller arrangement which has no translation or actuator requirements in order to allow the battery to have reduced frictional engagement with the battery compartment during installation or removal, and also to be well engaged with the battery compartment once installed. Rollers are provided which drop into recesses in the battery compartment at which point they are removed from load bearing engagement and thus, the recesses serve to locate the battery into the installed state in the compartment.

  • Patent number: 11725561
    Abstract: A sampling assembly for an exhaust gas aftertreatment system includes a body layer, an outer bowl, a first sampler, and an inner bowl. The body layer defines a cylindrical passage. The outer bowl is coupled to the body layer. The first sampler extends circumferentially along the body layer to the outer bowl. The first sampler includes a first sampler channel and a first sampler aperture. The first sampler channel is configured to provide exhaust gas into the outer bowl. The first sampler aperture is configured to receive the exhaust gas from the cylindrical passage and provide the exhaust gas into the first sampler channel. The inner bowl is disposed at least partially within the outer bowl and configured to receive the exhaust gas from the outer bowl and provide the exhaust gas into the cylindrical passage.

  • Patent number: 11608767
    Abstract: A sensor table mounting system includes an insulating blanket assembly and a senor table. The insulating blanket assembly is configured to surround an external housing surface of an exhaust aftertreatment component housing. The insulating blanket assembly includes an inner blanket surface, an outer blanket surface, and a first restraint. The outer blanket surface is opposite the inner blanket surface. The first restraint includes a first restraint first end that is fixed to the outer blanket surface. The sensor table includes a platform, a first standoff, a second standoff, a first footing, and a second footing. The first footing is offset from the platform by the first standoff and configured to be coupled to the first restraint. The second footing is offset from the platform by the second standoff and configured to be coupled to the first restraint.

  • Patent number: 11149609
    Abstract: An SCR system includes at least one catalyst, and an intake conduit. The intake conduit includes an intake conduit first sidewall, at least a portion of which defines a first curvature. An intake conduit second sidewall is coupled to the intake conduit first sidewall so as to define the intake conduit. A catalyst is fluidly coupled to the intake conduit through the intake conduit second sidewall. The intake conduit second sidewall is inclined at a first angle with respect to a longitudinal axis of the SCR system, such that an intake conduit second end cross-section of the intake conduit is smaller than an intake conduit first end cross-section. An intake conduit third sidewall is positioned at the intake conduit second end. The intake conduit is structured to produce an even flow split of the exhaust gas through the intake conduit internal volume towards the catalyst.

  • Patent number: 9297286
    Abstract: A system includes an internal combustion engine. An aftertreatment system is coupled to the internal combustion engine to receive an exhaust gas stream. The aftertreatment system comprises one or modules. Each module includes one or more emission reducing devices to reduce undesirable constituents in the exhaust gas stream from the internal combustion engine.
