Abstract

A common rail assembly used in a urea injection system, comprising at least a first common rail and a second common rail which are connected to each other, wherein the first common rail comprises a first housing, a pressure detecting device mounted on the first housing and a pressure adjusting device. The first housing comprises a first urea inlet channel, a first urea outlet channel, at least one first feeding inlet connected to the first urea inlet channel and at least one first back-flow outlet connected to the first urea outlet channel. The pressure detecting device is connected to the first urea inlet channel. The pressure adjusting device can connect/disconnect the first urea inlet channel to/from the first urea outlet channel. Also disclosed are a urea injection system and the application of the common rail assembly. A proper number of common rails selected based on different application requirements can be combined together by at least connecting the first common rail to the second common rail in series. The extension capability thereof is relatively high.
