Patent number: 8955545Abstract: Provided is a fuel tank system wherein the liquid levels of fuel in two fuel storage portions can be equally maintained, and the fuel amount in each fuel tank can be estimated with a high degree of accuracy. The fuel tank system is provided with a fuel tank in which a main tank portion and a subsidiary tank portion are formed; a siphon tube which extends from the main tank portion to the subsidiary tank portion, to transfer fuel from one tank portion to the other tank portion; and an electronic control unit (ECU) for determining whether or not the fuel is transferred via the siphon tube (in the transfer state). The ECU determines that the fuel is in the transfer state when the change rate of a sender signal is equal to or less than a predetermined threshold value (VF_th).Type: GrantFiled: March 31, 2011Date of Patent: February 17, 2015Assignee: Honda Motor Co., Ltd.Inventors: Shinya Murabayashi, Tamon Kimura, Kiyofumi Shida, Hiroaki Watanabe, Kengo Kobayashi, Yutaka Utsumi

Patent number: 8944268Abstract: A fuel introducing member is connected to an opening end of a siphon pipe forming a fuel tank. The fuel introducing member has an opening for introducing fuel within the tank, and the opening is formed in the upper surface of a cover section. A lid body is pivotably mounted to the upper surface. When the opening is above the level of fuel, the lid body closes the opening by the weight of the lid body, and when the opening is below the level of the fuel, the lid body floats in the fuel to open the opening. The opening is located below the upper end of the inner diameter of the opening end of the siphon pipe.Type: GrantFiled: February 2, 2010Date of Patent: February 3, 2015Assignee: Honda Motor Co., Ltd.Inventors: Shinya Murabayashi, Takeaki Nakajima, Kiyofumi Shida, Hiroaki Watanabe, Yutaka Utsumi, Kengo Kobayashi

Patent number: 8763656Abstract: A device for preventing a fueling error reliably prevents a fueling error by accurately preventing an insertion of a small-diameter nozzle without blocking an insertion of a large-diameter nozzle whose entrance should be permitted. Even if an end of a nozzle is strongly pressed to left-and-right shutter members (22), the shutter members (22) never rotate and move in an opening direction unless the shutter members (22) slide and move to an outside of a radial direction. Thus, the structure prevents the shutter members (22) from erroneously moving to a position in which the nozzle is allowed to enter from a blocking position.Type: GrantFiled: July 14, 2009Date of Patent: July 1, 2014Assignees: Nifco Inc., Honda Motor Co., Ltd.Inventors: Takahide Ichimaru, Yuki Takikawa, Syouichi Hokazono, Takeaki Nakajima, Shinya Murabayashi

Patent number: 8739821Abstract: A fuel introduction member is connected to an open end of a siphon tube which constitutes a part of a fuel tank. The fuel introduction member is provided with an opening through which a fuel is introduced from the tank into the siphon tube and from the siphon into the tank, a lid portion which is swung by the hydraulic pressure from the siphon tube so as to open the opening, and a float member which floats on the fuel in accordance with the rise of a fuel liquid surface in the tank to displace the lid portion in order to open the opening.Type: GrantFiled: June 25, 2010Date of Patent: June 3, 2014Assignee: Honda Motor Co., Ltd.Inventors: Shinya Murabayashi, Kengo Kobayashi

Patent number: 8590565Abstract: An improved fuel tank is disclosed. In the fuel tank, a shock-absorbing member comprising a plurality of foam members is mounted to an in-tank functional component provided inside a resin fuel tank body. When the fuel inside the tank sloshes up and down, the fuel strikes the shock-absorbing member, causing the force of the waves to be dispersed, and reducing the fuel sloshing sound created by the sloshing of the fuel.Type: GrantFiled: November 17, 2008Date of Patent: November 26, 2013Assignee: Honda Motor Co., Ltd.Inventors: Hiroaki Watanabe, Shinya Murabayashi, Kiyofumi Shida

Patent number: 8567458Abstract: A fuel filler apparatus of a vehicle of the invention, during normal operation, only permits insertion of fuel dispensing nozzles of a diameter within a predefined range, and prevents insertion of fuel dispensing nozzles whose diameter is smaller a lowest value or larger than a highest value of this range. The fuel filler apparatus includes a manual operation override mechanism which by a manual operation permits the insertion of only fuel dispensing nozzles of a diameter smaller than the lowest value of the range under special circumstances.Type: GrantFiled: October 6, 2008Date of Patent: October 29, 2013Assignee: Honda Motor Co., Ltd.Inventors: Yu Sato, Takeaki Nakajima, Shoichi Hokazono, Shinya Murabayashi

Patent number: 7997306Abstract: In an inner structure of a filler neck of a fuel filler tube, a nozzle support section for supporting a nozzle of a fuel filling gun at a gas station includes a pipe member having an inner diameter substantially equal to the outer diameter of the nozzle, and the nozzle is inserted in the pipe member when fueling. Fuel emitted from the nozzle is directed through the pipe member to an outlet end (distal end) of the nozzle support section, at which it starts flowing along an intermediate bent section of the filler tube. Thus, even when the fuel filling gun is not sufficiently inserted in the filler neck, i.e. inserted short of a standard inserted amount, the fuel is allowed to properly jet out in the bent section just as when the fuel filling gun is sufficiently inserted in the filler neck up to the standard inserted amount.Type: GrantFiled: July 11, 2008Date of Patent: August 16, 2011Assignee: Honda Motor Co., Ltd.Inventors: Kazuhiro Kobayashi, Shinya Murabayashi, Yutaka Utsumi, Takeshi Ohishi
