See full text

An aftertreatment system includes an inlet exhaust section, an outlet exhaust section, a first aftertreatment component, a first dosing module, and a second dosing module. The inlet exhaust section receives exhaust. The outlet exhaust section is in fluid communication with the inlet exhaust section. The first aftertreatment component receives the exhaust from the inlet exhaust section, treats the exhaust, and provides the exhaust to the outlet exhaust section. The first dosing module is positioned along the inlet exhaust section. The first dosing module is structured to selectively dose the exhaust with reductant. The second dosing module is positioned along the outlet exhaust section. The second dosing module is structured to selectively dose the exhaust with the reductant.
