Mounting assembly for a reductant injector

An engine exhaust assembly comprising:

• a curved exhaust line having an exhaust flow from an upstream end to a downstream end;
• a mounting assembly having:
• an upstream wall extending at least partially into the exhaust line and disposed in the exhaust flow;
• a downstream wall coupled to and located downstream of the upstream wall, the downstream wall extending at least partially into the exhaust line and disposed in the exhaust flow, the downstream wall having an interior surface facing the exhaust line downstream end and an exterior surface facing away from the exhaust line downstream end, the downstream wall including a plurality of bosses;
• a recess extending from the downstream wall in a direction away from the exhaust line downstream end;
• and
• a recess aperture formed in the recess;
• and
• an injector coupled to the downstream wall exterior surface and having a nozzle aligned with the recess aperture, the injector including a plurality of feet, wherein each of the plurality of bosses extends toward an associated one of the plurality of feet.

An engine exhaust assembly comprising:

• a curved exhaust line having an exhaust flow from an upstream end to a downstream end;
• an indentation having:
• an upstream wall extending at least partially into the curved exhaust line and disposed in the exhaust flow;
• a downstream wall formed integrally with and located downstream of the upstream wall, the downstream wall extending at least partially into the curved exhaust line and disposed in the exhaust flow, the downstream wall having an interior surface facing the exhaust line downstream end and an exterior surface facing away from the exhaust line downstream end, the downstream wall including a plurality of bosses;
• a recess formed integrally with the downstream wall and extending from the downstream wall in a direction away from the exhaust line downstream end;
• and
• a recess aperture formed in the recess;
• and
• an injector coupled to the downstream wall exterior surface and having a nozzle aligned with the recess aperture, the injector including a plurality of feet, wherein each of the plurality of bosses extends toward an associated one of the plurality of feet.
