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.

Control device and control method to exhaust purification device

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.

Exhaust gas purifying apparatus and method in internal combustion engine

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.
