摘要： Exhaust gas aftertreatment system for internal combustion engines operated with a lean mixture, wherein nitrogen oxides are reduced by an SCR catalyst, and particulates are removed by a particle separator or filter. A thermolysis catalyst is located near the engine in the exhaust gas split stream downstream of the supply point of the reducing agent. At temperatures above 135° C., this thermolysis catalyst vaporizes the water component of the aqueous urea solution. It contains a catalyst material that is thermally stable at exhaust gas temperatures occurring near the engine and preferentially reacts with the urea to form isocyanic acid. A hydrolysis catalyst is located in the exhaust gas stream downstream of the return of the split stream into the main stream of exhaust gas. The hydrolysis catalyst converts the isocyanic acid formed during thermolysis to ammonia and carbon dioxide using water vapor formed in the thermolysis catalyst.

摘要： A particle separator for the separation of particles from the exhaust gas stream of an internal combustion engine. The particle separator includes different heat transfer zones arranged at least in the main flow direction of an exhaust gas stream through the particle separator, different, that is, with respect to heat storage capacity and/or thermal conductivity and/or the heat-transfer properties from the exhaust gas stream to the particle separator. Each of these different zones makes it possible for a precisely defined amount of heat to be transferred from the exhaust gas stream to the individually assigned sections of the particle separator.

摘要： A particle separator and method for removing particles from an exhaust gas stream of an internal combustion engine. Differing flow regions having different flow conditions are formed in the particle separator. The differing flow regions are configured such that essentially particles having different, defined sizes and/or masses are adapted to be separated out of the exhaust gas stream in the differing flow regions. The exhaust gas stream is adapted to flow through at least portions of the particle separator.

摘要： A method for application in conjunction with an exhaust gas post-treatment system for metering an ammonia-releasing reducing agent into the exhaust gas stream of an internal combustion engine installed in a motor vehicle and operated with excess air. A control unit meters the quantity of reducing agent as a function of a stored model and during the operation of the internal combustion engine varies the metered quantity during certain operating phases and compares the change in the measured value of at least one NOx sensor installed downstream of the SCR catalyst with an expected value.
