    摘要： A method for metering ammonia into the exhaust-gas region of an internal combustion engine and a device for implementing the method. The ammonia storage capacity of an SCR catalytic converter situated in the exhaust-gas region of the internal combustion engine is utilized. After the internal combustion engine has been switched off, ammonia is introduced into the exhaust-gas region in front of the SCR catalytic converter. Thus, following a renewed start-up of the internal combustion engine, the ammonia required in the SCR catalytic converter for reducing the nitrogen oxides contained in the exhaust gas of the internal combustion engine are already available before an ammonia source is ready for operation. The procedure eliminates the need for a pressure storage of ammonia in the switched-off state of the internal combustion engine.

    摘要： The invention relates to a procedure for controlling the reducing agent in an exhaust gas post-processing system of a combustion machine with an exhaust gas duct, in which an SCR catalytic converter is provided in the direction of flow of the exhaust, wherein a reducing agent generation system has an NOx and CO/H2 generation unit,, an oxidation catalytic converter and a combined NOx storage / ammonia generation unit in the standard gas route of the reducing agent generation system, and, in order to reduce nitrogen oxide, ammonia is added as a reducing agent in front of the SCR catalytic converter by the reducing agent generation system, wherein source materials for the generation of ammonia are at least intermittently added to the NOx and CO/H2 generation unit via a fuel supply line and via an air supply line, wherein during the fat phase the air/fuel composition is changed in front of the oxidation catalytic converter in the form of a lambda modulation for a lambda value. It can thus be achieved that, in pulse mode, a high H2/CO yield can be achieved with a simultaneously low HC slip and the higher HC penetrations associated with the natural aging of the catalytic converter and the decreasing H2/CO yields are compensated. Influences resulting from the reactor geometry of the oxidation catalytic converter can be influences or compensated with the procedure in terms of its drive-away characteristic.

    摘要： A method of and apparatus for controlling the reducing agent in an exhaust gas aftertreatment system of an internal combustion engine with an exhaust gas duct in which an SCR catalyst is provided in the direction of flow of the exhaust gas. A reducing agent-generating system (RGS) comprising an NOx and CO/H2 production unit as well as a combined NOx storage/ammonia production unit in the standard gas path of the reducing agent-generating system. Ammonia is delivered upstream from the SCR catalyst to reduce nitrogen oxides, starting materials for producing the ammonia being fed at least in part to the NOx and CO/H2 production unit via a fuel inlet and an air inlet. An AGC matrix of the combined NOx storage/ammonia production unit is cooled at least intermittently by means of an inner and/or outer cooling device. Cooling results in the longest possible section of the running length (L) and thus the largest possible volume percent of the AGX matrix within the combined NOx storage/ammonia production unit having an optimum temperature range regarding the highest possible ammonia yield, which overall contributes to a great ammonia production rate.
