Abstract
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.
