    摘要： 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.

    摘要： An apparatus for posttreatment of exhaust gases of an internal combustion engine, using a reducing agent to be introduced into the exhaust gases, in particular a urea or a urea-and-water solution, having an improved mixing chamber into which stored reducing agent, via a reducing agent line, and compressed air via a compressed air line can be introduced to create a reducing agent-air mixture, and means for preventing a reverse flow of reducing agent or reducing agent-air mixture from the mixing chamber into the compressed air line are provided which have a spring-loaded sealing hose. This arrangement assures secure sealing off of an attachable compressed air system from the corrosive reducing agent.

    摘要： A method for mutual adaptation of a delivery module and a metering module of an exhaust emissions control system that has an exhaust gas conduit and a control module, the delivery module having a reservoir that has a venting valve and contains a uric acid solution that is conveyed via a delivery pump to a pressure regulating valve; and in the metering module, an air stream being compressed with the aid of a pump, conveyed to a pressure accumulator, and conveyed via a regulating valve, together with the uric acid solution, out of the pressure regulating valve to a metering valve, and being conveyed from there to an atomizer unit disposed in the exhaust gas conduit, the value of a reference pressure based on the pressure forming in the exhaust gas conduit being stored in the control module. A method for mutual adaptation of a delivery module and a metering module of an exhaust emissions control system having a control module, a respective parameter or characteristic curve being created for the delivery module and for the metering module and being introduced into the respective module as a machine-readable code. An apparatus for mutual adaptation of a delivery module and metering module for an exhaust emissions control system having an exhaust gas conduit and a control module, the value of a reference pressure based on the pressure forming in the exhaust gas conduit in the context of a calibration cycle being stored in the control module. A mutual adaptation of any arbitrary metering and delivery modules can thereby be implemented in a simple and economical fashion.
