  • Publication number: 20140136086
    Abstract: A vehicle controller performs a throttle-valve-late-close control in which the throttle valve is held open until a delay time has passed after the fuel cut is started, and an EGR-valve-open-close control in which the EGR valve is repeatedly opened and closed. Then, the throttle valve is closed and the EGR valve is opened. In a period from a latter period of an exhaust stroke to a preceding period of an intake stroke, a valve-overlap control is executed so that a variable valve timing controller is controlled to make both an intake valve and an exhaust valve opened. A pumping loss of an engine is sufficiently reduced and an energy-regenerate efficiency can be effectively improved.

    Abstract: A fuel cut-off valve assembly may include a housing disposed within a fuel tank and defining therein a float chamber communicating with a space defined in the fuel tank. The housing has a fuel vapor outlet hole, so that fuel vapor can flow from within the float chamber to a fuel vapor processing device. A float valve may be received within the float chamber so as to be vertically movable for opening and closing the fuel vapor outlet hole in response to change in a level of fuel within the fuel tank. The float valve may have a valve body and a buoyancy center positioned at a level higher than a central position of the valve body with respect to the height of the valve body.

  • Patent number: 7301245
    Abstract: A control system for a vehicle power supply for supplying power to a predetermined power receiving portion includes a first power generating power supply portion, second power generating power supply portion, and controller. The controller is arranged to set the voltage to be output to the power receiving portion from one of the power generating power supply portions in accordance with the output voltage of the other of the power generating power supply portions. With this arrangement, the power receiving portion is prevented from being supplied with an excessive amount of power, and when power regeneration is being performed by the second power generating power supply portion, the regenerated power is effectively used. Thus, the fuel economy of the vehicle can be increased.

  • Patent number: 6597180
    Abstract: A fault point location system comprises substation 1 installed along transmission and distribution line (TD line) to send a surge detection time (SD time), and master station 2 locates fault points based on the information. Substation 1 stores and updates past voltage or current waveforms of the TD line, stores a surge recognition level L2 (higher than a noise level), and a surge waveform starting level L1 (set lower than level L2), determines as the SD time, in the case where the voltage or current of the TD line exceeds level L2, the time at which the voltage or current first exceeded level L1 after going back through the waveforms stored from the time at which the surge recognition level was exceeded, and sends the SD time to master station 2 via the communication network.
