| titleOfInvention | Method, device, equipment and medium for predicting nitrogen oxide emission characteristics of diesel engine |
| abstract | The invention discloses a method for predicting the emission characteristics of nitrogen oxides of a diesel engine, which comprises the following steps: selective catalyst for obtaining ammoniaExhaust gas temperature value, exhaust gas flow rate value, NO at inlet of chemical conversion device X Concentration value, NO 2 Concentration value and NH 3 A concentration value; the temperature value, the flow value and NO of the exhaust gas at the inlet are measured X Concentration value, NO 2 Concentration value and NH 3 Inputting the concentration value into a pre-constructed nitrogen oxide prediction model; outputting the predicted ammonia-selective catalyst outlet equivalent NO X And (4) concentration. According to the nitrogen oxide emission prediction method disclosed by the invention, the nitrogen oxide emission concentration under various input conditions can be accurately predicted by establishing the nitrogen oxide prediction model, the calculation of the concentrations of various products is omitted, the model has strong stability and low calibration difficulty, and convenience is provided for the nitrogen oxide feedback control of SCR. |
