| titleOfInvention | Method and device for calculating NOx emission value of diesel engine |
| abstract | The invention relates to the technical field of diesel engine tail gas aftertreatment, and particularly discloses NO for a diesel engine X Method for calculating emission values for diesel engines NO X The method for calculating the emission value comprises the following steps: according to engine's original engine NO X Calculating urea injection quantities of different working condition points according to the emission value and the ammonia nitrogen ratio; calculating initial NO of each working condition point according to urea injection quantity, exhaust temperature, exhaust flow and SCR volume X The conversion efficiency; calculating the ammonia distribution uniformity coefficient, and calculating the ammonia distribution uniformity to the initial NO according to the ammonia distribution uniformity coefficient X A correction value of the conversion efficiency; initial NO based on uniformity of ammonia distribution X Correction value of conversion efficiency to obtain corrected NO X The conversion efficiency; according to engine's original engine NO X Emission value and corrected NO X Calculation of the conversion efficiency Final NO X The emission value. The invention also discloses NO used for the diesel engine X And calculating the emission value. The invention provides NO for a diesel engine X Method of emission value calculation for increasing NO X Accuracy of emission value calculation. |
