摘要： Methods and systems are provided for reducing degradation and issues related to noise, vibration and harshness (NVH) for a canister purge valve. In one example, a method may include sequentially increasing a duty cycle of a canister purge valve over a course of a purging operation to purge fuel vapors stored in a fuel vapor canister to an intake of an engine, while timing opening and closing events of the canister purge valve to coincide with pressure differences lower than a threshold in terms of pressure oscillations across the canister purge valve. In this way, purging of the canister may be efficient while additionally reducing degradation and NVH issues related to the CPV.

摘要： Methods and systems are provided for carrying out diagnostics of a variable orifice housed in a fuel vapor recovery line. In one example, a method may include, during a refueling event, comparing an expected fuel system pressure to an estimated fuel system pressure to detect if the variable orifice is stuck in an open position or a closed position.

摘要： A vehicular propulsion system, a vehicular fuel system and a method of operating an internal combustion engine. A separation unit that makes up a part of the fuel system includes one or more adsorbent-based chambers such that the separation unit may selectively receive and separate at least a portion of onboard fuel into octane-enhanced and cetane-enhanced fuel components. A supply tank includes three compartments where the first contains the onboard fuel, the second receives a vaporized adsorbate from the separation unit and condenses at least a part of it into one of an octane-rich fuel component or a cetane-rich fuel component, while the third may either store the condensed and enriched fuel component or help condense more of the vaporized adsorbate. The condensing takes place through heat exchange between the onboard fuel and the vaporized adsorbate that are present within the various compartments of the supply tank. A controller may be used to determine a particular operational condition of the internal combustion engine such that the onboard fuel can be sent to one or more combustion chambers within the internal combustion engine without first passing through the separation unit, or instead to the separation unit in situations where the internal combustion engine may require an octane-rich or cetane-rich mixture.

摘要： An exemplary system for improving gaseous venting from a fluid storage vessel includes a hollow member configured to receive a fuel nozzle, the fuel nozzle having an aspirate opening, a vent line fluidly connecting the fluid storage vessel and the hollow member, and a flow guide device fluidly connected to the hollow member and the vent line. The flow guide device includes a flow guide chamber having an inlet, a plurality of sidewalls, and an outlet, and a plurality of directional blades formed within the flow guide chamber. The plurality of directional blades direct a fluid flow through the flow guide chamber and the hollow member toward the aspirate opening of the fuel nozzle.

摘要： An evaporated fuel treatment device executes a pressure reducing control while monitoring inner pressure of a fuel tank, so that when the inner pressure of the fuel tank exceeds a predetermined value prior to fueling to the fuel tank, pressure reduction progresses within a range that the flow rate of a vapor passage does not exceed the boundary flow rate where the vapor passage is closed by a valve element of an ORVR valve, and also a valve opening speed of the closing valve is made higher as the inner pressure of the fuel tank becomes lower.

摘要： Methods and systems are provided for reducing degradation and issues related to noise, vibration and harshness (NVH) for a canister purge valve configured to regulate a flow of fuel vapors from a fuel vapor canister to an engine in response to a request to purge the fuel vapor canister of fuel vapors. In one example, a method may include purging the fuel vapor canister by synchronizing a timing of opening and closing events of the canister purge valve to correspond with instances where a pressure difference across the canister purge valve is lower as compared to higher in terms of pressure oscillations across the canister purge valve during the purging. In this way, higher loads and stress on the canister purge valve may be avoided, thus reducing degradation and NVH issues.

摘要： Example methods and apparatus to ensure grounding between vehicles during a vehicle-to-vehicle refueling operation are described herein. An example vehicle described herein is to receive fuel from a refueling vehicle via a vehicle-to-vehicle refueling operation. The example vehicle includes a fuel door to cover an inlet nozzle of a fuel tank, a lock to lock or unlock the fuel door, and a controller to cause the lock to unlock the fuel door if the vehicle and the refueling vehicle are electrically coupled.

摘要： An evaporative fuel treatment apparatus includes a canister, a vapor passage, an outside air introduction passage, a purge passage that connects the canister and an intake passage to each other, a sealing valve configured to open/close a flow channel of the vapor passage, a tank internal pressure sensor, a pressure sensor configured to detect a vapor pressure; and an electronic control unit. The electronic control unit is configured to determine whether or not there is an abnormality in the tank internal pressure sensor based on a change in the vapor pressure in changing over the sealing valve from a closed state to an open state, when an amount of change in the tank pressure in changing over the sealing valve from the closed state to the open state is lower than a first predetermined value.

摘要： A side-by-side off-road vehicle has a frame defining at least in part a cockpit area, and a power pack area being disposed rearward of the cockpit area. The vehicle has driver and passenger seats connected to the frame and disposed in the cockpit area on first and second sides of a longitudinal centerline of the vehicle. The vehicle further has a power pack connected to the frame and disposed at least in part in the power pack area. The power pack includes an internal combustion engine, an exhaust pipe, a muffler, and a fuel vapor containment system including a fuel evaporation canister. The fuel evaporation canister is disposed forward of the muffler, and at least a majority of the exhaust pipe and the fuel evaporation canister being disposed on opposite sides of the longitudinal centerline of the vehicle.

摘要： A straddled vehicle includes a vehicle body frame supporting a front wheel and a rear wheel, a seat fixed to the vehicle body frame, an engine, a fuel tank, and a canister to adsorb vaporized gas generated by evaporation of a fuel inside the fuel tank. The engine includes a crankshaft that rotates around a crank axis extending in the left-right direction and located lower than the seat. The fuel tank is located farther forward than the seat and higher than the engine. The canister is connected to the fuel tank through a gas pipe. The canister is located farther forward than the crank axis and lower than the fuel tank.
