Quick Details

[brief introduction] Germany, nitrogen oxide NOx sensor 5WK9 66141   NOX; the nitrogen oxide sensor assembly [details] "NOx sensor" in ppm (PPM) determination of nitrogen oxides in the exhaust gas level (NOx) concentration of nitrogen oxides, even small will not miss. This is a high precision real-time measurement of nitrogen oxides in the exhaust gas concentration of the world's first vehicle sensor, built in the application of zirconia ceramic oxygen pump function of the elements.
, the group and its partners NGK (NGK Insulators) intelligent sensor NOx joint development can play an important role in this respect. This sensor of ceramic sensor NOx concentration measurement in automobile exhaust and will be based on the input signal to the engine electronic control unit (ECU), to achieve the most efficient process control and postprocessing of engine combustion exhaust. In the diesel locomotive, this by ammonia selective catalytic reduction (SCR) injection system; in a gasoline engine through the combination of lean burn engine control technology of NOx storage catalyst regeneration period to achieve.
