Abstract: A compressor assembly includes a compressor housing having an inlet port configured to receive intake air and an outlet port configured to discharge pressurized air. A hollow section having an inner radial surface defines the inlet port of the compressor housing. A compressor wheel is disposed in the hollow section. A positive crankcase ventilation (PCV) passage is configured to allow airflow between a crankcase of an engine and the hollow section of the compressor housing. The PCV passage has an outlet opening that opens into the hollow section of the compressor housing and the inner radial surface includes an integrally formed raised boss surrounding the outlet opening and protruding into the hollow section.

Abstract: A sensor cleaning nozzle includes a nozzle housing including a first end and a second end defining a head portion, and a nozzle system arranged within the nozzle housing. The nozzle system includes a fluid feed member including a fluid feed inlet arranged at the first end and a fluid feed outlet arranged in the head portion. A cleaning nozzle is arranged in the head portion. The cleaning nozzle includes a nozzle inlet is fluidically connected to the fluid feed outlet, a nozzle outlet is exposed at the head portion, and a nozzle bore extends between the nozzle inlet and the nozzle outlet. The nozzle bore converges from the nozzle inlet toward the nozzle outlet along a first nozzle axis and diverges from the nozzle inlet toward the nozzle outlet along a second nozzle axis.

Abstract: An exhaust system for a diesel engine, includes an exhaust passage adapted to be attached to the diesel engine. A diesel oxidation catalyst is provided in the exhaust passage along with a selective catalyst reduction device disposed downstream from the diesel oxidation catalyst. A diesel exhaust fluid mixing system includes a diesel exhaust fluid injection nozzle and a mixing device defining a single inlet opening and a single outlet opening connected to one another by a partial spiral flow passage. The diesel exhaust fluid injection nozzle injects diesel exhaust fluid directly into the inlet opening of the partial spiral flow passage.

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.
