    Abstract: An object of the invention is to prevent a situation in which failure diagnosis for an exhaust system component in an internal combustion engine cannot be completed from continuing for an unduly long period of time. A warm-up system for an exhaust system of an internal combustion engine according to the invention includes a warm-up control performing unit that performs warm-up control for warming up an exhaust system component upon start-up of the internal combustion engine and a failure diagnosis performing unit that performs failure diagnosis for the exhaust system component after the completion of warm-up of the exhaust system component. If a situation in which the operation of the internal combustion engine is stopped after the start of operation of the internal combustion engine before the completion of the failure diagnosis for the exhaust system component performed by the failure diagnosis performing unit has been repeated for a predetermined period of time, the warm-up control performing unit changes the warm-up control performed upon start-up of the internal combustion engine after the predetermined period of time has elapsed to a control that can raise the temperature of the exhaust system component more quickly than the warm-up control performed during the aforementioned predetermined period.

    Abstract: 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).

    Abstract: A method is provided for controlling a Diesel Emission Fluid (DEF) injected quantity in a NOx reduction system employing a Selective Catalytic Reduction (SCR) catalyst, and a DEF injector for injecting the DEF to reach said SCR catalyst. The method includes determining a required quantity of DEF for the SCR catalyst at a given time. If the required quantity of DEF is at least equal to a threshold quantity, then a DEF injection is activated, otherwise the required quantity of DEF is stored in memory of an Electronic Control Unit (ECU). After a period, a further required quantity of DEF to be added to the required quantity is determined to determine a new required quantity of DEF. The new required quantity of DEF is continuously updated until the new required quantity of DEF is at least equal to said threshold quantity, at which point the DEF injection of the new required quantity of DEF is activated.
