    摘要： An engine exhaust purification device comprises: a selective reduction type NOx catalyst; an oxidation catalyst disposed on an upstream side of the NOx catalyst; a reducing agent adding device which adds an NOx reducing agent to an exhaust gas of an engine; a control device which controls the reducing agent adding device; and an NO2 ratio calculation device which estimates an NO2 ratio of the exhaust gas flowing into the NOx catalyst. The NO2 ratio of the exhaust gas flowing into the NOx catalyst is calculated by a catalytic reaction model where the oxidation reaction of NO in the oxidation catalyst is numerically formulated, and the NO2 ratio is reflected to calculate an amount of ammonia adsorbed on the NOx catalyst by a catalytic reaction model where a chemical reaction concerned with the reduction of NOx in the NOx catalyst is numerically formulated.

    摘要： In order to maintain a high NOx purification rate of a NOx reduction catalytic converter even in the case in which an NOx emission amount from an engine changes suddenly, in an exhaust emission purifying apparatus for an engine that reduces and purifies NOx in exhaust gas using ammonia generated from an injection-supplied urea aqueous solution, after engine starting, when an exhaust temperature exceeds a predetermined temperature T (step S1), an amount of urea aqueous solution corresponding to an actual engine operating state is injection-supplied (steps S3 to S5). On the other hand, at a change of the transmission speed ratio based on a driver's shift operation, an engine operating state after the change of the transmission speed ratio is predicted (steps S2, S6), and an amount of urea aqueous solution corresponding to the predicted engine operating state is injection-supplied before the change of the transmission speed ratio is completed (steps S7, S8).
