Method for the Operation of an Internal Combustion Engine Comprising an Emission Control System that Includes an SCR Catalyst |
摘要 |
A method for operating an internal combustion engine comprising an exhaust gas cleaning system that includes a SCR catalyst. In conjunction with a cold start and/or a warm-up of the internal combustion engine, the internal combustion engine is operated using a cold start engine operation method having predefineable values for predefineable operating parameters of the internal combustion engine. An amount of nitrogen oxides stored in the SCR catalyst is estimated, and the cold start engine operation method is activated when the estimation indicates that the nitrogen oxide storage amount exceeds a predefineable nitrogen oxide storage amount limit value.
