Abstract: Disclosed herein is a golf club head comprising at least one crown opening and at least one crown insert attached to the body and covering the at least one crown opening. The golf club head further comprises at least one sole opening and at least one sole insert attached to the body and covering the at least one sole opening. The golf club head additionally includes at least one weight member configured to clamp first and second ledges at selected locations along a sliding weight track. The golf club head also comprise a coefficient of restitution (COR) feature located on the sole of the golf club head. The at least one crown insert is formed from a composite material having a density between 1 g/cc and 2 g/cc. The at least one sole insert is formed from a composite material having a density between 1 g/cc and 2 g/cc.

Abstract: A decomposition tube for an exhaust treatment system includes a housing with a housing wall that defines an exhaust flow path for exhaust; a reductant delivery mechanism coupled to the housing and having a nozzle configured to deliver a spray of reductant into the exhaust flow path; and a mesh device with a mounting element mounted on the housing wall and a mesh basket secured to the mounting element proximate to the nozzle to enclose and intercept the spray such that effectively all of the reductant passes through the mesh basket and into the exhaust flow path prior to impinging on the housing wall.

Abstract: A power system including a selective reduction catalyst and an exhaust gas mixer positioned downstream thereof. The exhaust gas mixer includes an inlet opening a plurality of peripheral inlet openings and a plurality of swirler guides. The inlet opening is positioned to receive a first portion of exhaust gas exiting the SCR catalyst, while the plurality of peripheral inlet openings are positioned to receive a second portion of exhaust gas exiting the SCR catalyst. The swirler guides extend radially inwards from a respective peripheral inlet opening, so as to swirl the second portion of exhaust gas about and into the first portion of exhaust gas.
