摘要： A method of predicting nitrogen dioxide emission from an engine may include an initial nitrogen dioxide formation prediction operation of predicting an amount of nitrogen dioxide which is originally formed in the engine using a nitrogen dioxide formation model by an electronic control unit (ECU) while engine combustion is underway, a nitrogen dioxide reduction prediction operation of determining an amount of nitrogen dioxide which is reduced to nitrogen monoxide using a reverse reaction of the nitrogen dioxide formation model by the ECU based on the amount of formed nitrogen dioxide in the initial nitrogen dioxide formation prediction operation, and a final nitrogen dioxide emission determination operation of determining an amount of nitrogen dioxide which is ultimately generated by the engine by the ECU based on a difference between the amount of formed nitrogen dioxide and the amount of reduced nitrogen dioxide.
