Abstract: PROBLEM TO BE SOLVED: To provide a controller for an internal combustion engine capable of reducing vibration and noise caused in the multi-cylinder internal combustion engine in which an interval of explosion process occurs at unequal interval.
SOLUTION: Post injection is performed in such a way that amount of increase of crank shaft angle speed by post injection performed during a period of time when interval is longer among intervals of explosion process which occurs at unequal interval is larger than amount of increase of crank shaft angle speed by post injection performed during other period of time to reduce difference in fluctuation of crank shaft angle speed in each period of time. Consequently, it is possible to reduce vibration and noise in the internal combustion engine.

Abstract: PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine, in which a negative pressure can be controlled so that a physical quantity changing corresponding to an operating condition becomes a target value by taking the change in the negative pressure supplied to the negative actuator into consideration. SOLUTION: The controller is provided with an electric vacuum pump 81 for supplying the negative pressure to a movable vane actuator 23, an EVRV 82 for controlling the negative pressure supplied from the electric vacuum pump 81 into the movable vane actuator 23 by the difference between a target suction air quantity, and an actual suction air quantity of the suction air quantity and a negative sensor 85. When it is judged with the negative sensor 85 that the negative pressure between the electric vacuum pump 81 and the EVRV 82 changes, the motion of the EVRV 82 is adjusted and the movable vane actuator 23 is driven so that the negative pressure supplied into the movable vane actuator 23 is not changed by the difference in the negative pressure.

Abstract: PROBLEM TO BE SOLVED: To provide an exhaust emission control system for an internal combustion engine with a storage-reduction type NOx catalyst for elongating the retention time of a reducing agent in the storage-reduction type NOx catalyst.
SOLUTION: When the internal combustion engine is in a fuel-cut state, the reducing agent is supplied from a reducing agent supply device to the storage-reduction type NOx catalyst and a time for the reducing agent to reach the storage-reduction type NOx catalyst is computed. At the calculated time, a period for negative overlap between an intake valve and an exhaust valve is increased. With an increase of the period for negative overlap, the flow amount and rate of exhaust gas are reduced, and so the reducing agent resides in the storage-reduction type NOx catalyst for a longer time. As a result, the small amount of reducing agent can clean up nitrogen oxides (NOx) and sulfur oxides (SOx).
