Method for determining a pollutant concentration in exhaust gases and for determining emission masses in exhaust gas and measuring system for exhaust gas measurement

摘要

The invention relates to a method for determining a pollutant concentration in exhaust gas of an internal combustion engine, having a measuring system (10) comprising at least one pollutant concentration detector (16), wherein the measurement result of the pollutant concentration detector (16) is corrected with a moisture correction factor, in the determination of which a condensation of Water is considered during a cold start. Furthermore, a measuring system (10) for measuring exhaust gas is provided, comprising a pollutant concentration detector (16) for measuring a pollutant concentration in an exhaust gas, a temperature sensor (18) for measuring the exhaust gas temperature and an evaluation unit (20), wherein the evaluation unit (20) is formed to correct the values measured by the pollutant concentration detector (16) with a humidity correction factor, and wherein the evaluation unit (20) is adapted to determine the humidity correction factor taking into account a condensation of water during a cold start.
