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.

摘要： A zoom lens includes at least two lens groups that move for zooming. An object-side lens group is formed of a lens component having negative refractive power and a meniscus shape and a second lens component having positive refractive power and a meniscus shape, which may be in that order from the object side. Each of these lens components may be formed of a single lens element. Lens elements of the lens components satisfy certain conditions related to the half-field angle at the wide-angle end and the Abbe numbers of the lens elements. The zoom lens may include a third lens group, which may be stationary, with a middle lens group that moves nearer the object-side lens group and farther from the third lens group during zooming from the wide-angle end to the telephoto end. At least one surface of a lens component may be an aspheric surface.
