A method of managing wheel slip in a vehicle. The vehicle has a frame, an internal combustion engine, front and rear wheels operatively connected to the engine, a throttle valve for controlling a supply of air to the engine, a steering assembly operatively connected to at least the front wheels for steering the vehicle, and an unassisted continuously variable transmission (CVT) operatively connecting the front wheels and the rear wheels to the engine. The method includes: determining a sensed deceleration of the vehicle; comparing the sensed deceleration of the vehicle to a threshold deceleration; and increasing a torque output of the engine from a current engine torque output value to an increased engine torque output value when the sensed deceleration of the vehicle is greater than the threshold deceleration. A method for managing wheel slip in accordance with a drive mode of the vehicle is also disclosed.

A work machine includes an engine, a fluid path via which a fuel oil is supplied to the engine, a first filter provided in the fluid path, a pump provided between the engine and the first filter in the fluid path to suck and output the fuel oil, a second filter provided between the engine and the pump in the fluid path, and a third filter provided between the engine and the second filter in the fluid path.

A fuel supply structure for a saddled vehicle, includes: an upstream-side fuel supply system guiding fuel from a fuel tank to a fuel pump side; a downstream-side fuel supply system guiding the fuel from the pump to a fuel injection valve side; and an excess fuel return system returning excess fuel from the downstream-side fuel supply system to the tank side. A fuel hose joint is attached to the tank and includes: an insertion tube portion inserted into the tank and formed into a dual tube structure where an inner tube is covered by an outer tube; a first connection tube portion communicating with inside of the inner tube; and a second connection tube portion communicating with inside of the outer tube. A fuel suction hose is connected to one of the first and second connection tube portions, and a fuel return hose is connected to an other thereof.

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 canister includes a fresh air introducing port for introducing a fresh air into the canister. The fresh air introducing port is opened in a space formed by at least a tank cover. The canister is connected to a drain pipe for draining a liquid in the canister to the outside of the canister. The drain pipe extends rearward at a height same as or higher than a lower end of the tank cover. The drain pipe merges with a supplied-fuel drain pipe and extends to a lower portion of a vehicle. The supplied-fuel drain pipe drains a fuel around a fuel supply port of a fuel tank.

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.

A railway traction vehicle comprising a plurality of axles, a fuel gas power unit (112), a fuel gas storage assembly (118) including a predetermined number of fuel gas storage modules (122), and a fuel gas delivery network (120). The fuel gas storage assembly (118) comprises a plurality of identical fuel gas storage module receiving devices (124), and, for each of said receiving devices, an identical fuel gas coupling (126) for coupling a module (122) with said network (120). The modules (122) share a standardised configuration such that each of them can be received in any of said receiving devices (124) and coupled to the corresponding fuel gas coupling (126). They are distributed over said fuel gas storage module receiving devices (124) such that the load on the axles is optimised. The predetermined number is adapted to the amount of fuel gas needed by the vehicle to operate on a predetermined railway line. Preferred application to regional passenger multiple units.

Provided is power work equipment using a fuel container and/or a lubricating oil container that is/are easily replaced for the power work equipment, and supply(ies) liquid fuel and/or lubricating oil optimized for driving. A chainsaw (1A) (power work equipment) includes a main body (10) having an internal combustion engine (50), and a fuel container (90A) and/or a lubricating oil container (100A) detachably attached to the main body (10). A connection part (92) of the fuel container (90A) is connected with the fuel suction unit (60) in a liquid-tight manner, and the bag (91) is configured to collapse as liquid fuel (F) in the bag (91) decreases. A connection part (102) of the lubricating oil container (100A) is connected with a lubricating-oil suction unit (70) in a liquid-tight manner, and a bag (101) is configured to collapse as lubricating oil (L) in the bag (101) decreases.

An electrostatic discharge assembly for a vehicle includes a conductive plastic tether and a pipe connector. The conductive plastic tether has a first end and a second end. The first end is configured to be connected to a vehicle frame. The pipe connector is configured to connect the second end of the conductive plastic tether to a first fuel pipe of the vehicle.

A mower may include a body frame, a mower unit installed to the body frame, a grass collection container optionally installed at a rear portion of the body frame, a front-wheel support arm provided at a front portion of the body frame, a left front wheel and a right front wheel supported by the front-wheel support arm, a counterweight, and a weight bracket. The weight bracket may be provided on the front-wheel support arm and configured to attach the counterweight thereto. The counterweight may include a plurality of weight elements. The weight bracket may include a plurality of attachment portions. The at least one weight element may be attached to each attachment portion.
