The system includes a NOx storage reduction catalyst in an exhaust pipe of an engine, and a desulfurization process control unit that controls an amount of intake air introduced to the engine to enrich the exhaust gas, and performs a desulfurization process to the NOx storage reduction catalyst. The desulfurization process control unit is configured to gradually reduce an amount of intake air when the desulfurization process is commenced.

Abstract: An exhaust gas purification system with a diesel particulate filter in an exhaust passage of an internal combustion engine. A surface filtration cake layer formation enhancement control or a particulate matter generation amount reduction control is temporarily performed immediately after a forced regeneration treatment on the diesel particulate filter. The system and a method are directed to a particulate matter slip-through phenomenon in which the particulate matter slip-through amount temporarily increases immediately after particulate matter re-combustion in a forced regeneration treatment on the diesel particulate filter. The diesel particulate filter is disposed in the exhaust passage of the internal combustion engine and reduces the total amount of particulate matter emitted to the atmosphere immediately after the particulate matter re-combustion in the forced regeneration treatment on the diesel particulate filter.

Abstract: A photograph classification unit classifies the photographs for each scene in a music-feature information determination unit. A photograph feature acquisition unit identifies a feature of the photograph based on additional information of the photograph and a result of face recognition of the image. A tempo determination unit determines a tempo of music based on a time zone of image capturing, a range of the number of people captured in a photograph, the degree of smile, activities, etc. A melody determination unit determines information that confines a title, a feature value, a genre, etc., based on an event, a time zone, and a season at the time of image capturing, a city and a country in which the image capturing has occurred, etc. Based on the determined feature of the music, a music data output unit extracts and then presents matching music.
