An apparatus for metering a urea or a urea-water solution for delivery to a catalytic converter assembly for removing nitrogen oxides from the exhaust gases of a Diesel engine, includes a housing block supporting function components communicating via a line, formed by recesses in the housing block, for transporting the reducing agent, and the walls of the line are formed by the housing block. This apparatus assures a simple line layout for reducing agent with a minimum number of sealing points that is accordingly appropriate for large-scale mass production. |
