摘要： Provided is a technology enabling a temperature of an exhaust gas purifying device to rise more surely by operating an electric heater for a catalyst attached with the electric heater more steadily without exerting an excessive load on a battery. Included are the battery and the electric heater operating upon being supplied with electric power from the battery and heating an occlusion-reduction type NOx catalyst, wherein it is predicted, from a point that a SOx occluded quantity into the occlusion-reduction type NOx catalyst is equal to or larger than S1, that a SOx poisoning recovery process will be executed in near future (S102), and a charging level of the battery is increased (S106) by raising a voltage of power generation of an alternator (S103).

摘要： An object of the invention is to provide a technique for improving the efficiency of performance regeneration process that is executed on NOx storage reduction catalysts provided in a plurality of branch passages branching from the exhaust passage and reduce emissions of NOx from an internal combustion engine to the atmosphere. When the quantity of NOx discharged from an internal combustion engine and flowing into an exhaust pipe is smaller than a predetermined quantity, fuel serving as reducing agent is added through a fuel addition valve while torque change moderating process is executed (from T0 to T1). After that, a first flow rate control valve is closed to make the flow rate of the exhaust gas flowing in the first branch passage smaller than that in the second branch passage (from T1 to T3).

摘要： An exhaust gas purifying system for an internal combustion engine includes a first exhaust passage (22a) and a second exhaust passage (22b) into which an exhaust passage (21) of the internal combustion engine is bifurcated. NOx storage reduction catalysts (23a, 23b) and particulate filters (24a, 24b) are provided in each of the exhaust passages (22a, 22b). Fuel is supplied from a fuel valve (32) when NOx is to be released from the NOx storage reduction catalysts (23a, 23b). At a timing when the supplied fuel attaches to the NOx storage reduction catalysts (23a, 23b), one of exhaust control valves, for example, a first exhaust control valve (26a) is temporarily closed so as to keep the air-fuel ratio of exhaust gas rich. When NOx is released from the NOx storage reduction catalysts (23a, 23b) next time, a second exhaust control valve (26b) is temporarily closed after the fuel is supplied .

摘要： The problem is to regenerate the purification ability of an exhaust gas purification device more reliably or efficiently in an exhaust gas purification system that combines a plurality of branch passages (10a, 10b) branch off from an exhaust gas passage and exhaust gas purification devices (11a, lib). When the purification ability of an exhaust gas purification device (11a, lib) is regenerated, in the branch passage (10a, 10b) where the exhaust gas purification device (11a, lib) is provided whose purification ability is to be regenerated, the opening angle of an exhaust gas flow volume control valve (12a, 12b) is set to the minimum opening angle that can reliably transport a reducing agent that is added from a reducing agent addition means (14a, 14b) (S102 to S103). While the opening angle is maintained, the reducing agent is added (S105). After the addition of the reducing agent is complete, the opening angle of an exhaust gas flow volume control valve (12a, 12b) is closed completely (S108).

摘要： A low-octane fuel and a high-octane fuel stored in a low-octane fuel tank (5) and a high-octane fuel tank (7), both having known octane numbers, are injected from fuel injection valves (13a, 13b) into an intake port (12) at a mixing proportion that achieves a standard octane number set in accordance with the engine operation state. If knocking occurs during a predetermined steady engine operation state, the knocking is detected by a knock sensor (10b) and, corresponding to the knocking, the ignition timing is retarded from a basic ignition timing. A deviation in octane number is determined from the amount of ignition timing retardation with reference to a map, and is then corrected by the intake air pressure. On the basis of the corrected deviation in octane number, a deviation in the mixing proportion of the high-octane fuel is determined with reference to a map. The thus-determined deviation is added to a target mixing proportion computed corresponding to the standard octane number, thereby computing the present mixing proportion.
