Abstract
A mixer assembly for a vehicle exhaust system includes a mixer shell defining an internal cavity, wherein the mixer shell includes an upstream end configured to receive exhaust gases and downstream end, and a reactor positioned within the internal cavity. The reactor has a reactor inlet configured to receive injected fluid and a reactor outlet that directs a mixture of exhaust gas and injected fluid into the internal cavity. An inlet baffle is mounted to the upstream end of the mixer shell. The inlet baffle includes at least one opening that directs exhaust gas into at least one exhaust gas inlet to the reactor and a plurality of bypass openings that direct exhaust gas to bypass entry into the reactor. The inlet baffle includes a crowned portion that curves away from the reactor to provide for an increased open area within the internal cavity between the inlet baffle and the reactor.
