Abstract: An EGR control apparatus for an internal combustion engine, which is capable of accurately controlling an inert gas amount and an inert gas ratio of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state and reduced exhaust emissions. The EGR control apparatus includes a low-pressure EGR device, a high-pressure EGR device, and an ECU. The ECU calculates a target low-pressure opening, calculates an estimated value of an in-cylinder low-pressure inert gas flow rate, which is the estimated value of an inert gas amount included in low-pressure EGR gas supplied to the cylinders via an intake passage, calculates a target high-pressure opening using the estimated value, and controls low-pressure and high-pressure EGR control valves, using the target low-pressure opening and the target high-pressure opening.

Abstract: An exhaust gas purifying apparatus for an internal combustion engine is provided. A selective reduction catalyst is disposed in an exhaust passage of the engine for reducing NOx in exhaust gases from the engine under existence of a reducing agent. The reducing agent or a reactant for generating the reducing agent is supplied to the upstream side of the selective reduction catalyst. Occurrence of a reducing-agent slip in which the reducing agent is discharged to the downstream side of the selective reduction catalyst is determined. A storage amount indicative of an amount of the reducing agent stored in the selective reduction catalyst is temporarily reduced from the state where the storage amount is at the maximum, and thereafter the storage amount is increased until the occurrence of the reducing-agent slip is detected. An accuracy of the reducing agent supply is determined according to an occurrence state of the reducing agent slip when the storage amount is changed.

Abstract: An ECU controls to inject a small amount of fuel in an expansion/exhaust stroke under constraint of the minimum fuel injection capability of an injector at the time of warming-up of a catalyst. The ECU controls injection of fuel in expansion/exhaust strokes (expansion/exhaust stroke injection) at the time of warming-up of a catalyst. Fuel injection control is performed so that when temperature of the catalyst becomes higher than a predetermined temperature, fuel injection in the expansion/exhaust strokes is performed for a period of a predetermined ratio in a selected cycle period. The expansion/exhaust stroke injection is not performed in the other period. By effectively utilizing oxygen absorbed on the catalyst, while suppressing slip HC, the activation time of the catalyst can be shortened.

Abstract: A control system for an internal combustion engine, which is capable of enhancing the accuracy of fuel control and ignition timing control even when there is a possibility that the reliability of a calculated intake air amount lowers, and enables reduction of manufacturing costs. An ECU of the control system calculates a first estimated intake air amount according to a valve lift, a cam phase, and a compression ratio, calculates a second estimated intake air amount according to the flow rate of air detected by an air flow sensor. The ECU determines a fuel injection amount according to the first estimated intake air amount when an estimated flow rate Gin_vt calculated based on an engine speed, the valve lift, the cam phase, and the compression ratio is within the range of Gin_vt≦Gin1, and according to the second estimated intake air amount when Gin2≦Gin_vt.

Abstract: A control apparatus capable of ensuring high control accuracy even if a controlled object is in a transient state, when a control input is calculated based on a value obtained by correcting a value calculated by a feedforward control method using a value calculated by a feedback control method. The control apparatus calculates a fuel correction coefficient such that an output from an oxygen concentration sensor converges to a target output, and multiplies a basic injection amount by the coefficient to calculate a fuel injection amount. The basic injection amount is selected from three values according to the cause of a mapping error. Two of them are calculated by searching respective maps according to corrected throttle valve opening values and engine speed. The other is calculated by multiplying a value obtained by searching a map according to the opening and the speed by a correction coefficient.
