Systems and methods for implementing compensation strategies for a metering module with removable metering insert

摘要

A dosing module includes: a frame assembly comprising a plurality of plates; a first manifold configured to separately receive reductant and air and comprising: a first port and a second port; and a dosing insert, comprising: a base plate, a second manifold configured to separately receive the air and the reductant and return the air and the reductant to the first manifold, a third port selectively coupled to the first port , and a fourth terminal selectively coupled to the second terminal. When the third port is coupled to the first port and the fourth port is coupled to the second port, the reductant or air becomes the first port, from the first port to the third port, from the third port to the fourth port, from the fourth port to the second port Connection and led out of the dosing module from the second connection.
