  • Publication number: 20210272395
    Abstract: Generally, the current threshold value is set as a fixed value. Therefore, even in a case where an abnormality occurs in the load and the resistance value is small, when the power supply voltage applied to the load is low, the current value is also low, and falls below the threshold value, and there is a possibility that the overcurrent is not detected. In the present invention, by providing a second detection means that detects a load abnormality by calculating the resistance value of the load from information of the power supply voltage applied to the load, in addition to a first detection means that detects an overcurrent state that indicates the load abnormality using only current value information, it is possible to detect an overcurrent indicating an abnormality of the load even when the power supply voltage applied to the load is low.

  • Patent number: 8420272
    Abstract: In order to reliably avoid freezing in the generation stop state during intermittent operation, in the control device of the present invention that controls a fuel cell system to operate intermittently by switching between the generation state and the generation stop state of a fuel cell, it is determined whether to stop the generation operation during intermittent operation based on at least the temperature of a specific component that contains moisture from among the components constituting the fuel cell system. A valve, a passage, or a humidifier arranged on a flow path for a fuel gas or oxidizing gas may be selected as the specific component mentioned above. The temperature of the specific component is measured either directly by a temperature sensor provided corresponding to the specific component or indirectly based on either the operating state of the fuel cell system or the external air temperature.

  • Publication number: 20100282871
    Abstract: A fuel injection valve can be provided, with which temperature at needle valve seating position can be decreased and carburization of fuel and deposition of the carbide near the needle valve seating position can be prevented resulting in stable normal fuel injection control, and which is applicable to small and middle and also to large engines, particularly gas engines. The fuel injection valve is composed such that distance (A) from a seating face of the nozzle in the nozzle supporting body to a seating position of the needle valve in the nozzle is determined to be smaller than distance (B) from the nozzle seating face in the nozzle supporting body to the lower end of clearance between a nozzle insertion hole of the nozzle supporting body and a fitting part of the nozzle inserted into the nozzle insertion hole, thereby suppressing heat flow to the needle valve seating position.
