摘要： A storage tank having a wire or wire winding embedded in the wall of the storage tank is disclosed. The wire may be positioned such that it is compromised if the storage tank is deformed to a certain degree. The wire, for example, may form a helical shape proximate to the outer surface of the wall of the storage tank.

摘要： A fuel system, a vehicle, and a method of controlling an evaporative emissions system for the vehicle are provided. The fuel system has a fuel tank having a fuel fill port with a closure member. An evaporative emissions canister has a first port fluidly coupled to the fuel tank to receive vapor therefrom and a second port, with the canister positioned between an air intake for an engine and a vent to atmosphere. A filter or a second canister is supported by a bracket for movement between first and second positions, with the filter fluidly coupling the second port of the canister to the vent in the first position, and the filter spaced apart from and decoupled from the second port of the canister in the second position. The second port of the canister is in direct fluid communication with atmosphere when the filter is in the second position.

摘要： A method for a vehicle, comprising: indicating a true fill level of a fuel tank based on a fuel vapor canister temperature profile during a refueling event. In this way, a quantity fuel dispensed over the maximum fill level of the fuel tank may be accounted for, regardless of the fuel level sensor reading.

摘要： Methods and systems are provided for aging a new plastic fuel tank in a vehicle. In one example, during a plug-in event to recharge a battery of the vehicle, the fuel tank is isolated and the fuel pump is actuated to agitate fuel within the tank and increase fuel vapors until the plastic fuel tank becomes aged to a predetermined degree by fuel vapors generated therein. In this manner, the fuel tank is aged more rapidly, resulting in more accurate fuel level readings and less noise and vibration.

摘要： Methods and systems are provided for regulating evaporative emissions from a fuel system. In one example, a method may comprise spinning an engine unfueled responsive to a hydrocarbon concentration at a fresh air end of a fuel vapor canister increasing above a first threshold. The method may comprise spinning the engine to pull hydrocarbons away until a hydrocarbon concentration at a purge end of the fuel vapor canister, opposite the fresh air end, increases above a second threshold.

摘要： Methods and systems are provided for diagnosing a vehicle fuel system for a presence or absence of undesired evaporative emissions. In one example, a method comprises evacuating the fuel system of a vehicle to a variable vacuum target as a function of a volatility of fuel in a fuel tank positioned in the fuel system and a loading state of a fuel vapor storage canister configured for capturing and storing fuel vapors from the fuel tank. In this way, analysis of a pressure-bleedup portion of the diagnostic may be more reliable and completion rates of the diagnostic may be improved, while conducting the test in an environmentally fashion.

摘要： Methods and systems are provided for a fuel vapor canister with a modular configuration that may include a number of physically and releasably coupled canister modules, each module including a temperature sensor embedded therein and filled with one of a number of adsorbents. The temperature sensors may be utilized in combination with information regarding module position and the adsorbents within each module to indicate whether one or more of the individual canister modules are not functioning as desired, where such indications are determined during either refueling events, or during canister purging events. In this way, costs associated with servicing fuel vapor canisters may be reduced, the lifetime of fuel vapor canisters may be improved, an overall reduction in undesired evaporative emissions may be achieved, and the capacity of the canister may be readily adjusted based on emissions standards.

摘要： A pick-up truck bed having controllably magnetized areas for retaining cargo or attachment devices. A first permanent magnet may be attached below the lower surface of the truck bed with a second permanent being rotatable relative to the first permanent magnet to control the magnetic flux provided to retain objects in the truck bed. Alternatively, one or more electromagnets may be provided that may be turned on to retain objects in the truck bed and turned off to allow removal of objects.

摘要： Methods and systems are provided for the integration of a fuel level sensor and a fuel pressure sensor in a fuel tank within a fuel system. In one example, an integrated fuel pressure and fuel level sensor for a fuel tank may include a float arm of the fuel sensor coupled to a floating body and a pressure sensor (e.g., a fuel tank pressure transducer) coupled to the floating body, the integrated fuel pressure and fuel level sensor adapted to simultaneously measure fuel level and fuel vapor pressure of the fuel tank.

摘要： A fuel system is provided, including a fuel tank isolation valve comprising an actuation coil and a latchable valve shaft at least partially disposed within the actuation coil. A controller may be configured to indicate a position of the valve shaft based on a measured current-voltage relationship between the first and second terminal wires during a condition in which the magnetic field generated by actuation coil current has a flux density below a threshold required to adjust a position of the latchable valve shaft. In this way, the position of the latchable valve shaft may be indicated without moving the valve shaft, and without requiring a dedicated valve position sensor.
