  • Publication number: 20140060016
    Abstract: An exhaust gas purification control device for an internal combustion engine is provided with: a detection unit for detecting an air-fuel ratio or rich/lean state of exhaust gas that flows out of a first catalyst disposed at upstream side; estimating unit for estimating the oxygen adsorption amount on the first catalyst and a second catalyst; and an enrichment control unit for enriching or set the degree of richness temporarily by varying the degree of richness of injected fuel when the amount of the oxygen adsorption on the first catalyst and the second catalyst is estimated to be equal to or greater than a predetermined value. The enrichment control unit sets the degree of richness of the injected fuel to a first degree of richness that is greater than stoichiometry from the start of the enrichment process, and maintains the first degree of richness even after the output of the detection unit has reached a stoichiometric air-fuel ratio or rich/lean value.

  • Publication number: 20130330508
    Abstract: The present invention is transportable economically in a flat state, and easy to attach and detach, and can provide a curved surface simply while maintaining decoration and strength without craftsmanship. Slits are provided on a rectangular board panel comprising two or more layers of a hard material and a soft material. Two or more layers comprising a hard material and a soft material are laminated on a rectangular board panel, and slits having a length of ½ to ¾ of the vertical side are provided thereto. The use of slits makes formation of curved surfaces easy. Since there is no need to reinforce the outside to maintain the strength thereof, the board panel can be removed easily. Even if in external pressure is applied to the board panel, the flexibility of the hard material divided by the slits and the elastic characteristic of the soft material cause the pressure to be dispersed and absorbed.

  • Patent number: 8341937
    Abstract: An apparatus for an exhaust gas system includes a main exhaust passage, a main catalytic converter disposed in the main exhaust passage, a bypass exhaust passage, a bypass catalytic converter disposed in the bypass exhaust passage, and a valve configured to open or close a section of the main exhaust passage. The bypass exhaust passage bypasses the main exhaust passage between a branch point of the bypass exhaust passage out of the main exhaust passage and a junction with the main exhaust passage at a upstream side of the main catalytic converter. A first sensor indicates a first air-fuel ratio of exhaust gas in the bypass exhaust passage. A second sensor indicates a second air-fuel ratio of exhaust gas flowing into the main catalytic converter. A controller determines whether the valve in the closed configuration leaks exhaust gas based on the first and second air-fuel ratios of exhaust gas.
