Exhaust Sampling System Including A Mixer That Mixes Exhaust Gas And Dilution Gas

摘要

A mixing system for an exhaust sampling system is disclosed. In one example, the mixing system includes a mixing passage, an exhaust pipe, and a mixer. The mixing passage has a dilution gas inlet configured to receive a dilution gas. The exhaust pipe provides exhaust gas to the mixing passage. The mixer is disposed within the mixing passage and is configured to mix the dilution gas and the exhaust gas. The mixer has an inlet and an outlet, where the mixer inlet is configured to receive the exhaust gas, and the mixer outlet is disposed downstream of the mixer inlet. The mixer includes a plurality of radially extending lobes that are circumferentially disposed about a longitudinal axis of the mixer.
