Abstract: A control device of an exhaust purification device is provided with a plurality of addition valves that supply an additive pressure-fed from a pump, to exhaust purification catalysts separately from each other. As for addition valves constituting the plurality of addition valves the addition period of at least one addition valve is set so as to be different from the addition period of another addition valve.

Abstract: An internal combustion engine has a separate exhaust passage for each one of banks. An exhaust purifying catalyst is provided in each exhaust passage. The mass flow rates G1, G2 of exhaust gas that flow through the exhaust passages are individually estimated. The flow rate of exhaust gas is individually adjusted per each bank by controlling the operation of each one of exhaust gas recirculation valves such that the difference between the estimated mass flow rates G1, G2 is decreased.

Abstract: A preset waiting period is previously set on the basis of a signal in correspondence to a detection of a start point of a detection of a no-tooth portion of a signal rotor. In the case of a control for injecting a fuel after the preset waiting period has elapsed, an output of a signal indicating a start point of an actual detection of the no-tooth portion by a waveform shaping portion is delayed due to the existence of the no-tooth portion. A control computer corrects the preset waiting period to be shorter by an amount corresponding the delay. Accordingly, an accuracy of a fuel injection start timing control is improved.

Abstract: PM elimination or sulfur release are performed on both exhaust systems (exhaust passages 13L, 13R) using a common procedure regardless of the state of a catalyst arranged in each one of the exhaust systems. This reduces the number of recovery cycles of the catalysts and suppresses increase of fuel consumption caused by the PM elimination and the sulfur release compared to a case in which the PM elimination/sulfur release is carried out each time a request for catalyst control is generated by one of the exhaust systems. In the PM elimination control, the PM elimination is performed using a catalyst exhibiting a lowest catalyst bed temperature of the catalysts as a reference. In this manner, PM is prevented from remaining unburned. Further, in the sulfur release control, the sulfur release is performed using an average of catalyst bed temperatures of the catalysts as a reference. This maximally suppresses thermal deterioration of the catalysts and ensures sufficient release of sulfur.

Abstract: When conditions for regenerating purifiers are established, a control computer first causes an addition nozzle to supply a reducing agent to a first exhaust path. At this time, the control computer reduces a vane opening degree in a first supercharger and increases a vane opening degree in a second supercharger. Accordingly, the flow rate of exhaust gas discharged to the outside from the first exhaust path is reduced, and the flow rate of exhaust gas flowing to the intake path via a first exhaust gas supply path is increased. Also, the flow rate of exhaust gas discharged to the outside from a second exhaust path is increased, and the flow rate of exhaust gas flowing to the intake path via a second exhaust gas supply path is reduced. As a result, the purifiers are regenerated in a reliable manner, while suppressing variations in the flow rate of exhaust gas supplied to the intake path.

Abstract: Cylinder heads are each provided with a fuel injection valve, and an addition nozzle for adding fuel for activating an exhaust purifying catalyst to an exhaust manifold. There exists a non-exhaust period in which an exhaust gas does not flow out to exhaust passages from the exhaust manifolds during an operation of an engine. An ECU controls the addition nozzles in such a manner that the addition nozzles execute a fuel addition during periods except the non-exhaust period. Accordingly, the fuel added to the exhaust manifolds for activating the catalysts is avoided from collecting on a wall surface of an exhaust system without getting on an exhaust stream.

Abstract: Catalysts are respectively provided in a plurality of parallel exhaust paths of an internal combustion engine. A flow rate adjusting section adjusts a flow rate of an exhaust gas discharged from a first exhaust path to a downstream side, and a flow rate of an exhaust gas supplied to an intake path from the first exhaust path via a first exhaust gas recirculating path. A control section controls the flow rate adjusting section in such a manner that a ratio of the flow rate of the exhaust gas discharged from the first exhaust path with respect to the flow rate of the exhaust gas discharged from the other exhaust paths than the first exhaust path becomes smaller in the case that a temperature of the catalyst exists in a preset low temperature region than in other cases. Accordingly, it is possible to achieve an early activation in at least one of a plurality of catalysts while avoiding an addition of mechanisms.

Abstract: In an exhaust gas control apparatus and exhaust gas control method for an internal combustion engine, in which fuel is supplied to a purification mechanism provided in an exhaust passage so that a function of the purification mechanism is recovered. A flow rate of exhaust gas flowing in the exhaust passage or a value correlated with the flow rate is detected, and fuel supply timing is controlled based on a result of the detection. Accordingly, even when the flow rate of the exhaust gas flowing in the exhaust passage is variously changed based on the engine operating state, the fuel supply timing can be set based on the flow rate that is appropriately detected. Thus, it is possible to appropriately convey the supplied fuel to the purification mechanism using force of the exhaust gas.

Abstract: A main control computer commands a second sub-control computer to perform a reduced-cylinder operation when the coolant temperature detected by a coolant temperature sensor is greater than or equal to a reference temperature, and the exhaust temperature detected by a temperature sensor is less than a reference exhaust temperature and is within a reduced-cylinder operation allowable range in which a combination of the engine speed and the engine load is set in advance. The second sub-control computer deactivates a second cylinder group based on a command of the reduced-cylinder operation.
