Abstract
An emission reduction system is provided. The emission reduction system includes a tank configured to store a reductant. The emission reduction system also includes a pump configured to draw the reductant from the tank and supply the reductant to an exhaust system. The pump is further configured to draw in air from an ambient air source. The emission reduction system further includes a control assembly disposed in fluid communication with the ambient air source and the pump. The control assembly is configured to selectively allow the pump to access the ambient air source for purging the pump.
