Abstract
A system to mitigate diesel exhaust fluid deposits in vehicle exhaust system flexible couplings includes a diesel exhaust pipeline. A diesel exhaust fluid injector is connected to the diesel exhaust pipeline to inject a diesel exhaust fluid into the diesel exhaust pipeline. A flexible coupling is connected to the diesel exhaust pipeline. A diesel exhaust fluid collection device is positioned in the diesel exhaust pipeline between a connection location into the diesel exhaust pipeline of the diesel exhaust fluid injector and the flexible coupling. The diesel exhaust fluid collection device includes a liquid diesel exhaust fluid collection volume where an un-vaporized portion of the diesel exhaust fluid is collected.
