A multi-vessel reservoir assembly is provided. The multi-vessel reservoir assembly comprises a first fluid vessel, a second fluid vessel, and at least one linkage positioned between the first and second fluid vessels. The at least one linkage serves to maintain the first and second fluid vessels in fixed and spaced-apart relationship relative to one another. The first and second fluid vessels are independent and separately operable.

A work vehicle including: a drive device that has an internal combustion engine for driving a vehicle body; a first tank for storing fuel to be supplied to the internal combustion engine; and a second tank for storing fuel to be supplied to the internal combustion engine; wherein the first tank is disposed in front of or behind the drive device, and the second tank is disposed below the drive device so as to be separated from the first tank by a predetermined distance.

A work vehicle including a tank (31,131) formed so as to extend from a rear part of a vehicle body toward a center, wherein the tank includes: a first storage tank (32) located on the rear side of the vehicle body, and stores stored fluid (9); a second storage tank (34) located on a side close to the center in the front-rear direction of the vehicle body, and stores the fluid; a partition part (36) that separates the first storage tank and the second storage tank; a discharge member (49) that has a discharge opening (49a) extending and opened inside the second storage tank, and discharges, from the second storage tank, the fluid stored in the second storage tank; and a hollow tube member (60) that has a first end communicated with the first storage tank through the partition part so as to enable the stored fluid to flow, and a second end having a hollow tube opening (62) extending and opened toward the center of the vehicle body inside the second storage tank, wherein the hollow tube opening of the hollow tube member is located on the central side of the vehicle body with respect to the discharge opening of the discharge member.

Methods and systems are provided for enabling a vehicle for which a jet pump that functions to transfer fuel from a passive side to an active side of a saddle fuel tank is degraded, to reach a desired destination by the taking of mitigating action. The mitigating action includes conducting a driving maneuver in response to an indication that the jet pump is degraded, the driving maneuver conducted in order to transfer a desired amount of fuel from the passive side to the active side. In this way, a vehicle may reach a desired destination even under circumstances where the vehicle may otherwise be unable to reach the desired destination.

A multiple fuel tank purge system and method includes providing a pair of fuel tanks, including a main fuel tank for containing impure fuel and a separate, auxiliary fuel tank that contains commercial canned fuel. The engine runs on the impure fuel from the main fuel tank while the engine is in normal use, and then employs a shutdown cycle that switches to the commercial canned fuel from the auxiliary fuel tank for some pre-set time period. This arrangement allows the engine to be purged of the impure fuel (by burning the impure fuel during the shutdown cycle) and replaced by the commercial pre-mixed fuel before the engine is finally shut down. The system may further include a novel fuel cap with a fuel line, a tank within a tank fuel container, and/or an electronically actuated shutdown cycle mechanism.

Provided is a compressed natural gas (CNG) fuel system that can include a frame and at least one container. The frame can include a first side and a second side, with each side being configured to partly define a portion of an interior space. The at least one container can be configured to house or contain CNG and can be engaged to and partly encased by the frame. The at least one container can be partly located within the interior space of at least one of the first side or the second side. The frame assembly can be engaged to a chassis of a vehicle such that the at least one container is located either at least partially underneath a cab of the vehicle or at least partially behind a cab of the vehicle.

Methods and systems are provided for increase a rate at which a saddle fuel tank is depressurized responsive to a request for refueling. In one example, a method may include, responsive to the request for refueling, depressurizing a primary side of the saddle fuel tank to a secondary side of the saddle fuel tank, and commanding open a refueling lock coupled to the primary side to allow fuel to be delivered to the primary side when pressure in the primary side drops below a threshold pressure. In this way, the secondary fuel tank may be maintained at atmospheric pressure prior to the request for refueling, which may increase the rate of depressurization of the saddle fuel tank responsive to the request.

A fuel delivery unit for use within a vehicle fuel tank includes: a surge tank arranged on a wall of the fuel tank, a feed line extending from a region of the surge tank to a connector stub on the flange, and a wiring harness extending from the fuel pump to the flange. A flange-side holder forms a first force application point for fixing the wiring harness on a flange side, and a surge tank-side holder forms a second force application point for fixing the wiring harness on the surge tank side. The wiring harness, the flange-side holder and the surge tank-side holder together form a force absorber configured to protect the feed line and the connector stub during a vehicle impact by absorbing kinetic energy from the impact acting on the fuel delivery unit, thereby dissipating the kinetic energy.

A multi-vessel reservoir assembly is provided. The multi-vessel reservoir assembly comprises a first fluid vessel, a second fluid vessel, and at least one linkage positioned between the first and second fluid vessels. The at least one linkage serves to maintain the first and second fluid vessels in fixed and spaced-apart relationship relative to one another. The first and second fluid vessels are independent and separately operable.

Fuel pump for an internal combustion engine, wherein the fuel pump has: an auxiliary tank designed to receive a fuel flow from a low-pressure fuel pump; a pumping device drawing the fuel from the auxiliary tank through a suction duct; a Venturi choke arranged along the suction duct; and a degasification duct, which originates in a ceiling of the auxiliary tank and leads to the middle of the Venturi choke.
