  • Patent number: 11326567
    Abstract: The present disclosure is related to a method and an assembly for delivering fuel in a fuel tank (10), wherein the fuel tank comprises at least a first chamber (12) having a module pot (18) disposed therein and at least a first pump (30) adapted to deliver fuel from the first chamber to the module pot, and wherein a fuel pump (20) for delivering fuel to an engine is disposed within the module pot. In order to minimize the duty cycle of the pumps and therefore the energy consumption, it is proposed according to the present disclosure that a sensor device (22) is used to detect a predetermined minimum fill level in the module pot, wherein the pump disposed in the first chamber is activated when the minimum fill level is reached and is deactivated after a predetermined time interval or when a predetermined higher fill level in the module pot is reached.

  • Patent number: 11053898
    Abstract: A saddle riding vehicle includes: a body frame; a fuel tank; an upright internal combustion engine; a fuel injection device; and a high-pressure fuel pump. The high-pressure fuel pump is configured to be driven by one of an intake-side camshaft and an exhaust-side camshaft. The high-pressure fuel pump is mounted on an upper surface of a cylinder head cover in an attitude inclined rearward toward the other of the camshafts. The high-pressure fuel pump can thus be protected from disturbances from the sides, and the length of a high-pressure pipe for feeding fuel from the high-pressure fuel pump to the fuel injection device can be shortened. The vehicle protects the high-pressure fuel pump from disturbances from the sides, and prevents acceleration of vaporization of fuel by reducing heat which the high-pressure fuel pump receives from the cylinder block.

  • Patent number: 10145342
    Abstract: A fuel supply device includes a fuel pump, a filter case, a fuel passage, a discharge passage, and a residual pressure holding valve. A communication port opens at a shifted position of the fuel passage that is positionally shifted from the residual pressure holding valve toward the discharge passage. The fuel passage includes an outside passage part through which fuel flows from the communication port toward the discharge passage, and an inside passage part that throttles a flow of fuel flowing from the communication port toward the residual pressure holding valve more than the outside passage part. When a passage cross-sectional area of the inside passage part is converted into a passage cross-sectional area of a circular pipe, D which is a passage diameter of the circular pipe, and L which is a length of the inside passage part satisfy a relational expression of L/D?3.

    Abstract: A common width direction, along which a passage width of a communication passage section and a passage width of a pressurizing passage are defined, is perpendicular to an extending direction of a flow restricting passage section. A first passage wall surface and a second passage wall surface, which define the communication passage section therebetween, are opposed to each other in the common width direction. The flow restricting passage section opens in the first passage wall surface. The second passage wall surface is concavely curved relative to the first passage wall surface toward the flow restricting passage section, so that the passage width of the communication passage section is progressively reduced toward the flow restricting passage section within a predetermined range that is equal to or smaller than the passage width of the pressurizing passage.

    Abstract: A vehicle includes a fuel tank, a jet pump and a controller. The fuel tank has a passive side and an active side. Each of the sides includes a fuel level indicator. The jet pump is disposed within the active side and is configured to maintain a fuel level above a first threshold, based on each of the indicators, on the active side by siphoning fuel from the passive side during operation in a combustion mode. The controller is configured to, in response a battery charge level being below a second threshold during operation in an electric mode and a detected hill climb via a route guidance system, activate the jet pump to siphon fuel such that a fuel level within the active side rises above the first threshold.
