Abstract
A compressor includes a compressor impeller configured to rotate about an axis of rotation as intake gases flow along the compressor impeller. The compressor impeller includes an inducer and an exducer. The compressor impeller defines a first impeller end at the inducer and a second impeller end at the exducer. The second impeller end extends along a radial axis. The compressor further includes a compressor housing encasing the compressor impeller. The compressor housing defines a compressor volute. The compressor housing partially defines a diffuser in fluid communication with the compressor volute. The diffuser is elongated along a diffuser axis. The diffuser axis is obliquely angled relative to the axis of rotation. The diffuser axis is obliquely angled relative to the radial axis to minimize a turbulence of the intake gases flowing from the diffuser to the compressor volute.
