摘要： An internal combustion engine includes an intake port (5) leading to an engine cylinder (2). The intake port is divided into first and second passage section by a partition (11) extending in the intake port in a longitudinal direction of the intake port. A gas motion control valve (31) is arranged to open and close an upstream end of the second passage section (5B). A connection passage (12) connects an upstream end portion of the second passage section (5B) to the first passage section (5A). A fuel injector (41) is directed to inject fuel toward a valve opening of the intake valve through a space (5C) on the downstream side of the downstream end of the partition (11).

摘要： Sulphur oxides in the exhaust gas of a vehicle engine (1) are trapped by a nitrogen oxide trapping catalyst (5A). A controller (6) calculates the sulphur oxide poisoning amount of the trapping catalyst (5A) from the running condition of the vehicle (S13), and desulphating the sulphur oxides by a removing mechanism (3, 4, 14). The release amount of sulphur oxides per unit time due to desulphating is set as a parameter based on the sulphur oxide poisoning amount (S11), and by integrating the calculated release amount using the parameter, the current poisoning amount is calculated, and the release completion timing is precisely found.
