摘要： An object of the present invention is to provide a technology that enables reduction of NOx stored in an NOx catalyst with improved efficiency in an exhaust gas purification system for an internal combustion engine. According to the present invention, when NOx stored in the NOx catalyst is to be reduced, if the temperature of the NOx catalyst is lower than a specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased only by decreasing the air-fuel ratio of the exhaust gas discharged from the internal combustion engine, and if the temperature of the NOx catalyst is not lower than the specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased either only by adding reducing agent through reducing agent addition means, or by decreasing the air-fuel ratio of the exhaust gas discharged from the internal combustion engine and adding reducing agent through the reducing agent addition means.

摘要： An object of the present invention is to prevent, in connection with an exhaust gas purification apparatus regeneration system of an internal combustion engine, the possible travel distance of a vehicle after warning by a warning apparatus for warning excessive smallness of the fuel quantity is started from being unduly shortened even if regeneration control is executed while the warning is given by a warning apparatus. The system according to the invention has a warning apparatus that gives warning when the remaining fuel quantity is equal to or smaller than a first specified fuel quantity. When it is predicted that the regeneration control in which fuel is supplied to the exhaust gas purification apparatus will be executed when the remaining fuel quantity is equal to or smaller than the first specified remaining quantity, warning by the warning apparatus is started before the remaining fuel quantity becomes equal to the first specified remaining quantity (S104, S105).

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： During a rich spike control for an exhaust gas purification system for an internal combustion engine, a base air-fuel ratio AFb is decreased in a range where a combustion variation ΔCC does not exceed a permissible limit ΔCCL (S108). When the combustion variation ΔCC exceeds the permissible limit ΔCCL, the spike base air-fuel ratio AFbs is increased (S213). When the torque decrease amount ΔTD is above the permissible value ΔTDL, the spike base air-fuel ratio AFbs is decreased (S215). When the combustion variation ΔCC is above the permissible limit ΔCCL, and the torque decrease amount ΔTD is above the permissible value ΔTDL, the spike base air-fuel ratio AFbs is increased, and a fuel discharge time number EN is increased (S216).
