Abstract: A snorkel assembly for reading optimization of a sensor, wherein the snorkel assembly may be configured to be positioned around and spaced apart from the sensor. The snorkel assembly may include an upstream side and a downstream side. The snorkel assembly may include a cup section and a tube section extending from the cup section. The tube section may include an inlet opening on the upstream side of the snorkel assembly. The cup section may include an exhaust opening on the downstream side of the snorkel assembly.

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: In one aspect, a swirl can mixer assembly for mixing a fluid with exhaust gas exhausted from an internal combustion engine is provided. The assembly includes an inlet portion including an injection area configured to receive a fluid injector for dispensing the fluid into the exhaust gas for mixing with the exhaust gas in the mixing assembly to produce an exhaust gas/fluid mixture, an outlet portion, and an extended mixing conduit fluidly coupled between the inlet portion and the outlet portion. The extended mixing conduit is curved about at least a portion of a circumference of the outlet portion to induce a swirl in the exhaust gas/fluid mixture such that the exhaust gas/fluid mixture enters the outlet portion tangentially thereto.
