Abstract
An exhaust treatment fluid delivery system () may include a supply passageway (), a supply manifold (), injectors (), a bypass passageway () and first and second pressure sensors (). The supply passageway () receives the exhaust treatment fluid from a tank () and provides the exhaust treatment fluid to the supply manifold (). The bypass passageway () connects the supply passageway () with the return passageway () and includes a bypass valve () controlling fluid flow therebetween. The first pressure sensor () measures a first pressure of exhaust treatment fluid in the supply passageway () based upon which the bypass valve () is controlled. The second pressure sensor () measures a second pressure of exhaust treatment fluid in the supply manifold () based upon which the injectors () are controlled.
