摘要： An exhaust gas purification system for an internal combustion engine includes rich spike execution means for executing rich spike control in which the air-fuel ratio of an exhaust gas flowing into an NOx storage reduction catalyst is lowered to a target rich air-fuel ratio by supplying fuel to the exhaust gas while reducing oxides stored in the NOx storage reduction catalyst. The rich spike execution means executes the rich spike control (S 108) when the fuel injection amount has increased at a predetermined fuel increase rate or more by a predetermined fuel increase amount or more (S102, S105). It is possible to restrict the excessive amount of fuel to be supplied to the exhaust gas in rich spike control, and to sufficiently reduce oxides stored in the NOx storage reduction catalyst.

摘要： A fuel adding nozzle 17 is embedded including its front end member 17c into an internal wall of an exhaust port 40a formed within a cylinder head 100a. An injection passageway 101c guides, into the exhaust port 40a, the fuel jetted out of the front end member 17c of the fuel adding nozzle 17. A wall 102 provided between the front end member 17c and the exhaust port 40a decreases a heat receiving quantity of the fuel adding nozzle 17. A water jacket 110 is proximal to an outer edge of a nozzle seat 103, thereby efficiently transferring the heat contained in a gasket 17d to cooling water in the water jacket 110.
