  • Patent number: 10526984
    Abstract: A fuel evaporative emission control device including an electronic control unit that, when fuel tank inner pressure exceeds a first predetermined pressure, performs tank purge of closing a bypass valve and opening a sealing valve, discharging fuel evaporative gas inside the fuel tank into an air intake path of an engine in an operated state through a purge pipe and a vapor pipe, and treating the fuel evaporative gas, where, when tank purge is performed, if a first predetermined period of time passes after closing of the bypass valve without the fuel tank inner pressure falling to or below the first predetermined pressure, the sealing valve is closed and tank purge is stopped.

  • Patent number: 10369881
    Abstract: An evaporative fuel treatment apparatus, which is loaded on a hybrid vehicle equipped with a fuel tank and a battery mounted forward of the fuel tank, has a sealing valve for sealing evaporative fuel in the fuel tank. The sealing valve is disposed between the battery and the fuel tank and is arranged above the battery. The evaporative fuel treatment apparatus can prevent fuel leakage from the sealing valve more reliably.

  • Patent number: 10232712
    Abstract: A display device is provided with a fuel gauge (40) that displays the amount of fuel remaining in a fuel tank (24) (remaining amount) of a hybrid vehicle (10) provided with an engine (13) that consumes fuel supplied from the fuel tank (24) and generates power by driving wheels (15) or rotating a motor (11). The hybrid vehicle is provided with a non-traveling/non-power generating mode, or in other words, a fuel consumption mode or an engine maintenance mode in which the engine (13) is forced to run and consume fuel for purposes other than traveling or generating power. Of the fuel (41a) displayed in the fuel gauge (40), the region (41aa) corresponding to the amount of fuel consumed in the non-traveling/non-power generating mode is displayed so as to be distinguishable by color from another region (41ab).
