Abstract (en)
[origin: EP1854985A2] The method involves storing soot particles of exhaust gas in an exhaust gas after treatment system (2), and providing characteristic diagrams, which reproduce a functional correlation between soot concentration and nitrogen oxide concentration for different operating conditions of an internal combustion engine. The actual nitrogen oxide in the gas is determined by a nitrogen oxide sensor (3), and the determined concentration is used together with parameters for reading actual soot concentration as output signal, where the parameters describe the conditions as an input signal for the diagrams. An independent claim is also included for a direct injection internal combustion engine for executing an exhaust gas soot concentration determining method.
