摘要： An exhaust emission control system of an internal combustion engine is provided which controls the oxygen concentration of exhaust passing through the exhaust emission control device according to the flow rate of exhaust flowing through an exhaust passage when the exhaust emission control device is regenerated, so that the regeneration is completed within a short period of time while the filter is prevented from being damaged by melting during the regeneration. This improves the exhaust emission control performance and reliability of the filter.

摘要： An exhaust emission control system of an internal combustion engine capable of post injection is disclosed which provides control such that the injection timing in sub injection is set to a point earlier than the target injection timing when the sub injection is started, and the injection timing in the sub injection is then delayed to the target injection timing. This realizes the post injection under the optimum conditions and enables an efficient rise in the exhaust temperature while inhibiting deterioration of the drivability due to a rapid change in torque.

摘要： A method for restricting an excessive temperature rise in an internal combustion engine according to the present invention can provide a technology that enable to restrict an excessive temperature rise of a filter more reliably in an internal combustion engine having the filter provided in the exhaust passage for collecting particulate matter in the exhaust gas. In that method, when the running state of the internal combustion engine becomes idle running during the filter regeneration process, the oxygen concentration in the exhaust gas flowing into the filter is reduced. After that, when the running state of the internal combustion engine shifts from the idle running to a running state with an engine load higher than in the idle running, the oxygen concentration in the exhaust gas flowing into the filter is gradually increased.

摘要： A filter is arranged in an exhaust passage of an engine. The filter supports a catalyst. An accumulating amount estimating means detects differential pressure of the filter to estimate an amount of soot accumulating on the filter. An oxidizing condition detecting means detects an oxidizing condition of soot accumulating on the filter. A forcible oxidizing means increases temperature of the filter more than oxidizing temperature of soot for forcibly oxidizing soot accumulating in the vicinity of the catalyst of the filter. When the oxidizing condition detecting means detects a condition, in which soot accumulating on the filter is only partially oxidized, the accumulating amount estimating means estimates the amount of soot accumulating on the filter after oxidizing soot accumulating in the vicinity of the catalyst using the forcible oxidizing means.
