Abstract (en)
[origin: WO2009033597A1] The invention relates to a method and a device for determining specific emissions as an exhaust gas characteristic of an internal combustion engine. Said method is characterised in that the exhaust gas mass flow (3) is determined as the first operating parameter and the engine power output (2) as the second operating parameter, the nitrous oxide mass flow (3) and the engine power output (2) are derived from a respective measured value that deviates from the operating parameter and the exhaust gas characteristic is calculated as a quotient from the corrected exhaust gas mass flow (3) and the engine power output (2).
