Method for calibrating nitrogen oxide sensor for determining concentration of nitrogen oxide in exhaust gas of internal combustion engine of motor car, involves adjusting sensor parameter based on determination of capacity of gas sensor

摘要

The method involves determining a decomposition product of exhaust gas component i.e. nitrogen oxide, in a storage chamber (30). Capacity of a gas sensor i.e. nitrogen oxide sensor (100), for storage of the decomposition product and/or charge and/or time-dependent course of a filling degree is determined, and a sensor parameter e.g. sensor characteristic, is adjusted based on the determination of the capacity of the gas sensor. A decomposition electrode (21) is provided in a decomposition chamber (20), and a hollow chamber electrode (31) is provided in the storage chamber. Independent claims are also included for the following: (1) a computer program comprising a set of instructions to perform a method for calibrating a gas sensor (2) a computer program product comprising a set of instructions to perform a method for calibrating a gas sensor.
