Abstract: Methods and systems are presented for improving operation of an evaporative emissions system. In one example, the methods and systems estimate a fuel vapor concentration based on output of a fuel tank level sensor and output of a fuel pressure sensor. A canister purge valve is adjusted to an initial position at a beginning of a fuel vapor purging cycle to reduce a fuel vapor purging time.

Abstract: User interface customization based on user navigational signals is described herein. A computer system causes a device to present first information associated with a first item in a first network page. The computer system receives first data indicating a first interaction with the first information and determines whether the first interaction corresponds to a first request for information about a set of items associated with the first item or to a second request for a removal of the presentation of the first information. If the first interaction corresponds to the first request, the computer system causes the device to present a second network page that shows second information associated with a second item of the set of items. If the first interaction corresponds to the second request, the computer system causes the device to remove the first information from being presented in the first network page.

Abstract: An apparatus and a system are disclosed for preventing fuel starvation in an off-road vehicle that may be operated on a severely inclined surface. A vehicle having a fuel tank for a fuel delivery module disposed in the fuel tank. A fuel pump assembly is disposed in the fuel tank and a slip ring joint is assembled to the fuel delivery module. One or more tubes are assembled to the slip ring joint that extends and retracts relative to the slip ring joint toward and away from the walls of the fuel tank. A remote fuel pick-up is assembled to the tube so that when the vehicle is operated on an inclined surface, the remote fuel pick-up is extended and rotates inside the fuel tank to move toward and away from an inner surface of the fuel tank and follows the fuel contained in the fuel tank.

Abstract: Systems and methods are presented herein for detecting a degradation condition in a variable volume device of a fuel tank of a vehicle. In one example, the issues described above may be addressed by a diagnostic method for a vehicle with a valve and a fuel tank having a variable volume device internal to the tank, comprising: operating the fuel tank over a diurnal cycle; and differentiating between degradation of the fuel tank and the variable volume device based on a fuel tank pressure at a plurality of different valve conditions; and indicating the differentiated degradation.

Abstract: Methods and systems are provided for diagnosing leaks in a fuel system. In one example, a method may include monitoring a fuel level in a vehicle fuel tank of the fuel system during refueling and indicating degradation of the vehicle fuel tank and/or a bellows coupled to the vehicle fuel tank based on the monitored fuel level. In some examples, indicating the degradation may further be based on a rate of fuel supplied to the vehicle fuel tank during the refueling and/or a vehicle fuel economy. In this way, degradation to the vehicle fuel tank and the bellows may be passively determined with minimal specialized components in the fuel system.

Abstract: Methods and systems are provided for conducting diagnostics to indicate whether a fuel system and/or an evaporative emissions system of a vehicle has a source of undesired evaporative emissions, or not. A method comprises conducting such a diagnostic via evacuating the fuel system to a target vacuum, then sealing the fuel system from atmosphere and monitoring a pressure bleed-up in the fuel system, and dynamically adjusting a pressure bleed-up threshold responsive to one or more conditions that impact the pressure bleed-up during the diagnostic, and indicating undesired evaporative emissions responsive to the pressure bleed-up reaching the adjusted pressure bleed-up threshold. In this way, interpretation of the results of such a diagnostic may be more robust, completion rates may improve, and engine operation may be improved.

Abstract: A method for operating a vehicle with an internal combustion engine is provided that includes regulating a pressure in a fuel tank by scheduling an engine start-up event based on a rate of change of the fuel tank pressure to reduce fuel tank venting emissions, where the rate of change of the fuel tank pressure is determined based on an ambient temperature and an in-tank pressure.

Abstract: 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 conducting a test for undesired evaporative emissions stemming from a fuel system of a vehicle via in a first operating mode, evacuating the fuel system to a variable vacuum level through an entirety of a fuel vapor canister configured to capture and store fuel vapors, and in a second operating mode, evacuating the fuel system to the variable vacuum level through a portion of the fuel vapor canister. In this way, the diagnostic may be conducted in an environmentally friendly fashion, where analysis of a bleed-up portion of the test is not impacted by fuel volatility at the time of the diagnostic.
