Burner-Based Exhaust Replication System with Rapid Exchange of Exhaust Aftertreatment Devices: 11,408,802


A burner-based exhaust replication system that includes mechanisms for rapidly exchanging exhaust aftertreatment devices for testing. The exhaust replication system has a test leg for delivering exhaust to an exhaust aftertreatment device and a bypass leg for bypassing exhaust around the test leg. The test leg is equipped with a rotating drum that holds a number of exhaust aftertreatment devices. The drum is rotatable to selectively align the aftertreatment devices with the test leg and is moveable laterally in a direction parallel to the test leg to aid in sealing the test leg to the aftertreatment device.
