Patent number: 10369881Abstract: 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.Type: GrantFiled: October 27, 2016Date of Patent: August 6, 2019Assignees: MITSUBISHI JIDOSHA ENGINEERING KABUSHIKI KAISHA, MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventors: Kenichi Kunii, Takayuki Sano

Patent number: 10232712Abstract: 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).Type: GrantFiled: October 21, 2015Date of Patent: March 19, 2019Assignee: MITSUBISHI JIDOSHA KOGYO KABUSHIKI KAISHAInventors: Norifumi Iwaya, Kenichi Kunii
