Abstract: An apparatus and system are disclosed for enhancing aftertreatment regeneration. The system includes an internal combustion engine and an exhaust manifold directing the engine exhaust to an aftertreatment system. The system may further include an exhaust gas recycle system and a turbocharger. The system further includes a fuel injector mounted on the exhaust manifold that provides fuel to assist in regenerating an aftertreatment component. The fuel injector is mounted in an apparatus also including a flow dampener, an extender, and a residence chamber. The apparatus allows the fuel to be injected in a high temperature location where it will experience residence time at temperature, and experience shear forces passing through the turbocharger. The extender allows the fuel to be injected at a place in the exhaust manifold where recycling of injected fuel into the engine is minimized.

Abstract: A modular wall panel system in which individual panels are constructed with a lightweight aluminum frame. In a preferred embodiment, the frame is substantially filled with a foam core material and decorative display surfaces are affixed to opposite sides thereof. One edge of the panels contains a plurality of specially shaped connector pins, while the opposite edge has a plurality of connector slots having a "dogbone" configuration. Therefore, a similar panel placed adjacent to the first panel may be mated thereto by engagement of the connector pins with respective connector slots in the other panel. The pins/slots are shaped and sized so that the connector pin may enter/exit the connector slot at either end of the dogbone but not in the center slot of the dogbone. Secure coupling with fast assembly/disassembly is thereby achieved, without tools or detachable components. Furthermore, the dogbone shape of the slot allows panels to be removed from either side.
