A saddle-ride type vehicle for enabling the placement of canisters with a required absorption-chamber capacity in a compact manner. The saddle-ride type vehicle includes a head pipe supporting a steering shaft connecting with a handlebar; a vehicle-body frame connecting with the head pipe; a fuel tank placed to the rear of the head pipe and supported on an upper portion of the vehicle-body frame; and a pair of canisters for absorbing evaporated fuel introduced from the fuel tank. The canisters are vertically placed under one side portion of the fuel tank in a position along the vehicle-longitudinal direction.

A multi-use fuel tank flange assembly facilitates the attachment and removal of multiple components thereto, such as a draw and return tube assembly, a fuel filler neck, and a cover plate. Each of these components may be removed from the flange without damage to the component, the flange or the fuel tank. Multiple flanges may be used on a single fuel tank to allow multiple components to be secured to the single fuel tank.

The present invention relates to a flange that includes a base region, a raised region, and a sloped region there between. The sloped region includes concave and convex curved regions positioned in a plane parallel to an elongate axis of the flange, and concave and convex curved regions positioned in a plane perpendicular to the elongate axis of the flange so as to reduce stress within and fatigue failures of the flange.

The present invention relates to an all in one fuel tank assembly, and a process of manufacturing the same, for use in commercial vehicles, and more particularly, to an all in one fuel tank assembly that allows multiple components to be manufactured as a single integral structure, such as a single extruded device including a draw tube, a return tube, a fuel sender device, and a vent, for example.

A vapour recovery system recovers vapour coming from a vehicle tank. The system includes a valve that is positionable in a closed position, an open position creating a passageway with a first size, and one or more intermediate positions each creating a passageway with a size smaller than the first size. The system also includes an electronic controller to control an actuator to position the valve in a sequence of positions over time. The sequence includes at least one of the intermediate positions during a time period larger than 1 second. The valve is arranged in a line of the vapour recovery system between a vapour outlet of the vehicle tank and the atmosphere. The actuator is a stepper-motor based linear actuator. The controlling includes selecting at least one intermediate position, and the selection includes selecting a number of steps to be set from a predetermined reference position.

One embodiment of a molded fuel tank includes a fuel tank molded as one piece of rotationally molded cross-linked polyethylene material. One embodiment may include molding a fuel tank wall as a single layer of material with a metal component fastening structure positioned within the single layer fuel tank wall as it is molded.

An evaporative emissions control system configured for use with a vehicle fuel tank includes a purge canister, an accelerometer, first and second vent tubes that terminate at first and second vent openings, a first vent valve, a second vent valve, a vent shut-off assembly and a control module. The accelerometer senses acceleration in an x, y and z axis. The first vent valve is fluidly coupled to the first vent tube. The second vent valve is fluidly coupled to the second vent tube. The vent shutoff assembly selectively opens and closes the first and second valves. The control module estimates a location of liquid fuel based on the sensed acceleration from the accelerometer and determines which vent opening is one of submerged and about to be submerged based on the estimated location of the liquid fuel. The control module closes the vent valve associated with the determined vent opening.

A tank tube bracket for a tank comprises a receptacle extending along an axis and receiving a tank tube and a passage adapted to pass a fluid through the tank tube bracket. A distal end of the passage is directed toward the axis of the receptacle.

A stiffness reinforcement device for a fuel tank of a vehicle may include a body including a pair of pillars formed at both lateral end portions of the body; an upper fusing portion molded to an upper part of the body integrally and fused to an upper plate of the fuel tank; and a lower fusing portion molded to a lower part of the body integrally and fused to a lower plate of the fuel tank.

When the internal combustion engine is stopped, a pressure reduction pump performs a pressure reduction while a first open/close valve and a second open/close valve are closed. After that, a control unit determines whether a fault occurs in a second purge pipe between the second open/close valve and an intake pipe based on a measured value obtained by an obtaining portion immediately after the second open/close valve is opened.
