    Abstract: An object is to reduce the increase in the fuel consumption or the increase in emissions caused by processing for raising the temperature of an NOx catalyst in an exhaust gas purification apparatus for an internal combustion engine having the NOx catalyst arranged in an exhaust passage of the internal combustion engine. To achieve the above object, an exhaust gas purification apparatus for an internal combustion engine according to the present invention executes processing for raising the temperature of the NOx catalyst on condition that a temperature change ratio with a predetermined amount of assumed temperature rise of the NOx catalyst is equal to or higher than a reference value. According to the present invention, it is possible to activate the NOx quickly while keeping the unwanted increase in the fuel consumption and emissions caused by the temperature raising processing small.

    Abstract: A control apparatus for an internal combustion engine is provided which can accurately correct a valve timing deviation of an intake valve caused by a variable operating angle mechanism or variable phase mechanism.A variable operating angle mechanism (28a) for making the operating angle of an intake valve (24) variable is provided. Operating angle command values (operating angles 1 and 3) of two points in front and back at which the intake air amount is decreased by a predetermined amount with respect to the value that is judged to be a maximum value of the intake air amount when the operating angle (command value) is kept changing, are acquired. Then, an intermediate value which is at an equal distance from the operating angle command values of the two points is calculated as the maximum operating angle command value. Then, this maximum operating angle command value is compared with a reference characteristic to execute the calculation of the deviation amount of the valve timing and the correction of the deviation.

    Abstract: The present invention pertains to a control system for an internal combustion engine equipped with an exhaust gas purification apparatus including an NOx catalyst having an ability of reducing NOx and a particulate filter, and its object is to prevent deterioration in the acceleration performance while preventing an increase in exhaust emissions when the temperature of the NOx catalyst is low. The control system for an internal combustion engine according to the present invention includes an exhaust gas purification apparatus provided in an exhaust passage of the internal combustion engine and including an NOx catalyst having an ability of reducing NOx and a particulate filter, intake air quantity restriction means for restricting the intake air quantity in relation to the temperature of the NOx catalyst, fuel restriction means for restricting the fuel injection quantity in relation to the intake air quantity of the internal combustion engine, and trapped PM amount obtaining means for obtaining the amount of PM trapped in the particulate filter. When the amount of PM trapped in the particulate filter is not larger than a predetermined amount and the internal combustion engine is in an accelerating operation state, the control system corrects a restriction value of the fuel injection quantity in relation to the intake air quantity of the internal combustion engine and the temperature of the NOx catalyst.
