  • Patent number: 10677125
    Abstract: An exhaust gas purification apparatus for an internal combustion engine includes the adsorbent, the catalyst and the heat generating element, wherein in cases where the residual capacity of the battery is smaller than a first predetermined value required for raising the temperature of the catalyst to an activation temperature thereof, and in cases where the residual capacity of the battery is larger than a second predetermined value which is smaller than the first predetermined value and which is required for raising the temperature of the adsorbent to a predetermined temperature at which the adsorbent exhibits adsorption performance required at the time of starting of the internal combustion engine, an amount of electric power to be supplied to the heat generating element from the battery is adjusted such that the temperature of the adsorbent becomes the predetermined temperature.

  • Patent number: 10648391
    Abstract: A controller estimates a first estimated adsorption amount which is an amount of adsorption of ammonia in the SCR catalyst at the time when the SCR catalyst is assumed to be in a predetermined abnormal state, estimates a second estimated adsorption amount at the time when the SCR catalyst is assumed to be in a predetermined normal state, calculates a first slip development temperature based on the first estimated adsorption amount, and calculates a second slip development temperature based on the second estimated adsorption amount. The controller, when carrying out an abnormality diagnosis based on a concentration of ammonia in an exhaust gas at the downstream side of the SCR catalyst, carries out diagnostic temperature control so as to control the temperature of the SCR catalyst to a temperature which is equal to or more than the first slip development temperature and is less than the second slip development temperature.

  • Patent number: 10626778
    Abstract: When a user requests start-up of an internal combustion engine while PM removal control is in execution or immediately after execution of the PM removal control is completed, an electronic control unit informs the user of the vehicle of a first alarm, so that the user recognizes that the internal combustion engine cannot be started up immediately. This makes it possible to suppress the discomfort caused because the internal combustion engine is not started up.

  • Patent number: 10556262
    Abstract: A tool storage device is disposed on a side of a press brake. In the tool storage device, a lower tool holder is lifted up from lower tool holder support members, is moved forward or backward, and both end sides in a left-and-right direction of the lower tool holder are lowered after being passed through recessed portions formed on the lower tool holder support members (step (a)). The lowered lower tool holder is conveyed forward, and is positioned to a same height as a height of a lower tool mounting portion in a lower table (step (b)). The lower tool held in the lower tool holder is transferred to the lower tool mounting portion by a tool replacement device, and is mounted on the lower table (step (c)). The lower tool mounted on the lower table is returned into the tool storage device (step (d)).
