摘要： A turbocharger and engine cylinder head assembly includes a center housing rotating assembly (CHRA) and an engine cylinder head defining a receptacle for receiving the CHRA, the engine cylinder head defining a compressor volute. A diffuser is defined for receiving and diffusing the compressed air from the compressor wheel and supplying the compressed air to the compressor volute. The assembly includes a cap formed separately from the engine cylinder head and removably secured to the engine cylinder head, the cap defining one wall of the diffuser. An opposite wall of the diffuser is defined either by the engine cylinder head or a portion of the center housing, depending on whether the CHRA slides into the receptacle compressor-wheel-first or turbine-wheel-first. The compressor volute can be located on a turbine side of the diffuser.

The inner shroud includes a radially outwardly facing first surface, a radially inwardly facing second surface, and a plurality of grooves extending into the second surface. The grooves are arranged such that a space having a component in a circumferential direction is defined between adjacent grooves. During operation of the engine, the grooves guide purge air out of the disc cavity toward the hot gas path such that the purge air flows in a desired direction with reference to a direction of hot gas flow through the hot gas path.

摘要： A blade outer air seal (BOAS) segment has a plurality of cooling passages axially extending through a platform of the BOAS segment. The passages each have an inlet defined in a radially outer surface and an exit defined on a leading edge of the platform. At least one of the passages positioned close to respective circumferential sides of the platform extends linearly from one of the inlets and is skewed away from the axial direction to cool a corner area of the platform.
