An exhaust gas purification system includes an adsorbent containing an adsorbent element for adsorbing harmful compounds such as hydrocarbon in an exhaust gas and a catalyst containing a catalyst element for lowering the harmful compounds in the exhaust gas, each disposed in the exhaust gas pipe of an internal combustion engine. When an oxidizing gas is added to the exhaust gas or amounts of combustion gas and fuel are regulated, for a given period, in the process in which the hydrocarbon in the exhaust gas produced at the cold start-up of the internal combustion engine are adsorbed by the adsorbent and desorbed from the adsorbent as a temperature of the adsorbent is increased by the exhaust gas, an exhaust gas composition containing excessive oxygen is provided and the desorbed hydrocarbon are oxidized on the catalyst. With this arrangement, the harmful compounds in the exhaust gas, in particular, the hydrocarbon produced in a large amount at the cold start-up of the engine can be effectively purified.
摘要:
An exhaust gas purification system for an internal combustion engine is herein disclosed which comprises an exhaust system having an adsorption flow path provided with an adsorbent capable of adsorbing harmful components such as hydrocarbons in an exhaust gas, and a catalyst flow path provided with at least one catalyst for decreasing the harmful components in the exhaust gas, the exhaust gas purification system being characterized in that an outlet of the adsorption flow path is joined to the catalyst flow path at a predetermined position on the upstream side of the catalyst to form a joint portion; the exhast gas produced at least at the time of the operation start of the internal combustion engine is divided so as to flow through the adsorption flow path and the catalyst flow path in a predetermined ratio, so that part of harmful components such as the hydrocarbons are adsorbed by the adsorbent in the adsorption flow path; and when the adsorbed harmful components begin to desorb from the adsorbent with the temperature rise of the adsorbent, the catalyst on the downstream of the joint portion is activated.

A storage apparatus has a physical storage area used by an external apparatus, a drive interface unit, a power supply unit, and a storage controller executing data write processing from the external apparatus to the storage drive and data read processing from the storage drive through the drive interface unit, and a drive control interface unit. The power supply unit inputs power supply information to the drive interface unit. Any one of the processing units acquires the power supply information of the power supply unit through a data network path to the drive interface unit for the data write processing and the data read processing, and determines whether or not a failure occurs in the power supply unit supplying the operation power to the storage drive and the drive interface unit, on the basis of the acquired power supply information.
摘要:
A power device of the present invention makes a plurality of DC/DC converters redundant, and supplies power individually to a plurality of disk drives. Each first DC/DC converter is respectively made correspondent to a subgroup. One first DC/DC converter is connected to the disk drives respectively inside one subgroup, and the other first DC/DC converter is connected to the disk drives inside the other subgroup. A second DC/DC converter is made correspondent to all of the subgroups. Second DC/DC converters respectively supply direct-current power to any one disk drive of the disk drives in the subgroups.
