    摘要： In an exhaust passage, a pressure detection means is provided on the upstream side of a filter, and an exhaust throttle valve is provided on the downstream side of the filter. And, when the operational state of the internal combustion engine is a steady operational state (in a step S101), the opening amount of an exhaust throttle valve is controlled so that the upstream pressure detected by the pressure detection means becomes a constant value (in a step S103).

    摘要： An internal combustion engine system is capable of reducing soot and NOx simultaneously, and prevents the occurrence of an undesirable situation where a generation amount of soot is increased in accordance with frequent transitions between a first combustion mode and a second combustion mode. In the system, the first combustion mode in which an amount of inert gas supplied to the combustion chamber is larger than an amount of the inert gas that causes the generation amount of soot to become a peak, such that soot is hardly generated, and a second combustion mode in which an amount of the inert gas supplied to the combustion chamber is smaller than the amount of the inert gas that causes the generation amount of soot to become a peak, are selectively performed. When conditions are such that switching between the first combustion mode and the second combustion mode has or may occur frequently, the execution of the first combustion mode is controlled. The frequency of switching can be determined, for example, based on a frequency of change of the engine load, an operational state of the engine, or road information.

    摘要： An internal combustion engine performs a second mode of combustion where the EGR is less than the EGR gas that peaks the production of soot. The engine then performs a first mode of combustion where the EGR is greater than the EGR that peaks the production of soot. During the second mode, the engine curbs hydrocarbon supplied to an exhaust gas control catalyst by performing a combustion where hydrocarbon does not increase. The exhaust gas temperature discharged becomes relatively high and the EGR rate is set to zero. The engine then increases the hydrocarbon supplied to the catalyst by performing a combustion that increases the hydrocarbon. The temperature of exhaust gas discharged becomes relatively high, and the EGR rate is gradually increased. Accordingly, the engine quickly warms up the catalyst while preventing problems that occur, like clogging of an exhaust gas recirculation passage.

    摘要： An engine where first combustion where the amount of the EGR gas in the combustion chamber is larger than the amount of EGR where the amount of production of soot peaks and a second combustion where the amount of EGR gas in the combustion chamber is smaller than the amount of EGR gas where the amount of production of soot peaks are selectively switched between and where an NOx absorbent is placed in the exhaust passage of the engine. When SOx should be released from the NOx absorbent, the first combustion is performed under a rich air-fuel ratio, while when the second combustion is performed, auxiliary fuel is injected during the first part of the suction stroke or the expansion stroke and the injection timing of the main fuel is delayed by a large extent.

    摘要： An internal combustion engine that selectively switches from a first combustion in which an amount of an exhaust gas recirculation gas within a combustion chamber is more than the amount of the exhaust gas recirculation gas when an amount of soot generated reaches a peak amount to generate substantially no soot, that is, a low temperature combustion, and a second combustion in which the amount of the exhaust gas recirculation gas within the combustion chamber is less than the amount of the exhaust gas recirculation gas when the amount of soot generated reaches the peak amount. The switching is selectively performed, such that, a stable low temperature combustion corresponding to the air fuel ratio is performed by shifting the area for performing the low temperature combustion to the high load side as the air fuel ratio is reduced.
