  • Patent number: 10221741
    Abstract: An exhaust gas control apparatus has an exhaust gas control element other than an SCR catalyst. A temperature increase treatment unit executes temperature increase treatment that increases temperature of exhaust gas flowing into the exhaust gas control apparatus so as to increase the temperature of the exhaust gas control element to a specified target temperature. In this case, when operation of the internal combustion engine is stopped while the temperature increase treatment unit is not executing the temperature increase treatment, addition of an additive to the SCR catalyst from an addition valve is executed after operation stop of the internal combustion engine. When operation of the internal combustion engine is stopped while the temperature increase treatment unit is executing the temperature increase treatment, addition of the additive to the SCR catalyst from the addition valve is not executed after operation stop of the internal combustion engine.

  • Publication number: 20180236518
    Abstract: In a tool storing device handling a tool mounting stocker in which a punch and a die of a press brake are mounted in one stocker with rear surfaces facing each other, each of the stockers is supported on both sides by endless belts having one driving shaft, and the endless belts are circulated so that each of the supported stockers does not protrude to a worker side, whereby a position of a path line of the appropriate one of the stockers can be freely positioned at a position of the path line PL of a tool holder on the press brake side. This enables rapid and easy tool replacement by a bending robot by storing not only the tool made of the punch and the die but also the hand for the robot together.

  • Publication number: 20180179932
    Abstract: When it is determined that there is a possibility of start-up of an internal combustion engine while regeneration control is in execution during stop of the internal combustion engine, processing of the regeneration control is stopped. Accordingly, as compared with the case where the regeneration control is continuously executed when the internal combustion engine is started up, temperature increase in a filter can be suppressed: Therefore, even when an increased amount of oxygen is supplied to the filter, an oxidation reaction is suppressed, so that overheating of the filter can be suppressed.
