| titleOfInvention | A kind of NOx emission monitoring method that real-time online calculates |
| abstract | The present invention relates to the NOx emission monitoring methods that vehicle exhaust post-processing technology field more particularly to a kind of real-time online calculate.Normally meet the urea injection arteries and veins spectrogram of discharge according to engine first, engine pedestal cycle bleeder test is carried out in the way of reducing urea injecting quantity, so that the downstream the SCR NOx ratio discharge value under the rack state of cyclic operation of laws and regulations requirement is reached OBD limit value, obtains urea injection limit value arteries and veins spectrogram；Engine Universal Characteristics test is carried out based on urea injection limit value arteries and veins spectrogram；The downstream the SCR NOx concentration limit value arteries and veins spectrogram under different operating conditions is established, and then obtains the downstream SCR NOx mass flow limit value arteries and veins spectrogram；Meet under the conditions of monitoring enables in engine and judges whether the integrated value of NOx actual mass flow in the downstream SCR in set period of time is greater than the integrated value of the downstream SCR NOx mass flow limit value, if more than exceeded fault alarm is then discharged, the accuracy and stability of NOx emission monitoring are improved. |
