  • Patent number: 10989701
    Abstract: 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.

  • Patent number: 10927737
    Abstract: A system for purifying exhaust gas includes a controller to predict a possibility of ammonia (NH3) slip occurring at the rear end of a selective catalytic reduction on a diesel particulate filter (SDPF) by comparing a convective heat transfer value (h) with a first predetermined value. The controller determines whether an engine is rapidly accelerated, and performs a control to prevent introduction of ammonia downstream of the SDPF when the ammonia slip is predicted to occur.
