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: 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: 6851458Abstract: An on board refueling vapor recovery system includes a first fuel vapor passage for connecting a fuel tank with a canister, a second fuel vapor passage for connecting an inlet portion of a fuel filler pipe with the fuel vapor passage (a tank main body) and a check valve in the second fuel vapor passage. The check valve is integrated with a first quick connector of a resin hose (a resin tube) which constitutes the second fuel vapor passage. Therefore, the number of man hours required for assembling the on board refueling vapor recovery system can be reduced. In addition, the space required for installing any of the on board refueling vapor recovery system can also be reduced. Furthermore, the amount of released fuel evaporative emissions or fuel evaporative emissions can be reduced.Type: GrantFiled: August 16, 2002Date of Patent: February 8, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takeaki Nakajima, Tadahisa Nakamura, Takeshi Honda, Kiyofumi Shida, Hiroto Inoue

Patent number: 5858034Abstract: A dust filter unit for a canister is provided. An inlet port and an outlet port are formed in a housing and opening into the atmosphere. A communication port is formed in the housing and leading to the canister. A filter is arranged within the housing at a location between the inlet port and the output port. A first one-way valve is arranged within the housing at a location between the communication port and the outlet port, for allowing evaporative fuel to flow from the communication port to the outlet port. A second one-way valve is arranged within the housing at a location between the filter and the communication port, for allowing fresh air to flow from the filter to the communication port. Thus, the inlet port, outlet port, communication port, and first and second one-way valves are all provided in one piece within the housing.Type: GrantFiled: March 20, 1997Date of Patent: January 12, 1999Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kiyofumi Shida, Takeaki Nakajima

Patent number: 5855198Abstract: A canister system is installed in a vehicle having a body having a substantially closed space defined therein, and a subframe mounted on the body and having a substantially closed space defined therein. An air intake passage is connected to a canister for drawing and delivering fresh air into the canister, and an air exhaust passage is connected to the canister for exhausting air resulting from removal of evaporative fuel components from an evaporative fuel-air mixture by adsorption of the evaporative fuel components by the canister into the atmosphere. An open end of the air intake passage remote from the canister is formed in the body of the vehicle, and an open end of the air exhaust passage remote from the canister is formed in the subframe.Type: GrantFiled: May 5, 1997Date of Patent: January 5, 1999Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takeaki Nakajima, Shoichi Hokazono, Koichi Hidano, Kiyofumi Shida, Masaaki Horiuchi
