Methods and systems are provided for estimating a level of water in real time for a vehicle and using the said estimation to perform one or more vehicle control strategies. In one example, a method may include adjusting a valve in a fuel system of the vehicle responsive to a level of water through which the vehicle is passing. In this way, water inhalation into the vehicle fuel system may be avoided.

Mitigation for driving through high water

A system for an engine, comprising: a fuel vapor canister coupled to a fuel tank; a thermal jacket comprising a phase-change material, the thermal jacket spatially sheathing the fuel vapor canister; and an engine coolant passage positioned to transfer thermal energy between engine coolant and the phase-change material. In this way, the phase-change material may buffer the temperature of the fuel vapor canister by absorbing heat generated during hydrocarbon adsorption, and returning the heat to the vapor canister during hydrocarbon desorption. By coupling the phase-change material to engine coolant, the thermal capacity of the thermal jacket can be increased, as heated coolant can thus transfer thermal energy to the phase-change material to replace the thermal energy transferred to the canister during hydrocarbon desorption.

System and methods for managing fuel vapor canister temperature

A system for an engine, comprising: a fuel tank; a thermal regulator comprising a phase-change material, the thermal regulator coupled to the fuel tank; and an engine coolant passage positioned to transfer thermal energy between engine coolant and the phase-change material. In this way, the temperature of the fuel tank may be managed passively by the phase-change material, and actively by engine coolant, thereby allowing heat energy to be shunted away from the fuel tank, cooling the fuel within the fuel tank, and reducing fuel vapor concentration, thus enabling a fuel vapor canister with a reduced size.

System and methods for managing fuel tank temperature

A fuel storage system includes a storage vessel including a dielectric liner, a voltage sensor formed by a pair of plates disposed on opposing surfaces of the liner, and a controller configured to determine a gas pressure in the storage vessel based on voltages measured by the sensor.

Fuel storage system and method for detecting a gas pressure therein

A refueling assembly of an engine is provided. The refueling assembly includes a housing, a door positioned within the housing and a flow guide positioned within the housing and downstream of the door including an inlet in fluidic communication with the door, an outlet to flow fuel into a downstream filler pipe in fluidic communication with a fuel tank during a refueling operation, a planar nozzle seating section receiving a fuel nozzle during the refueling operation, and a contraction section positioned downstream of the planar nozzle seating section.

Refueling assembly including a flow guide

A capless nozzle for a vehicle fuel filler canal, includes a conical portion; and a non-conical portion having a stop formed therein configured to limit travel of a filler pipe in one direction when the pipe is inserted in the filler canal.

Vehicle fueling apparatus

A fuel filler system for an automotive vehicle includes a filler pipe connected with a fuel tank and an interceptor mounted about an open end of the filler pipe, with the interceptor and filler pipe defining a generally annular contaminant collector having a drain extending from the collector. A filler cap closes both the open end of the filler pipe and the open end of the interceptor, so as to prevent ambient contamination from entering either the contaminant collector or the filler pipe. Removal of the filler cap from the filler pipe first causes venting of the fuel tank into the collector before a sealing condition between the filler cap and the interceptor is released.

Fuel filler system for automotive vehicle

Systems and methods for performing leak testing on fuel system components in hybrid vehicles during engine-off operating conditions are disclosed. For example, a fuel tank may include a pressure accumulator which may be filled with fuel via a fuel pump in order to generate a vacuum which may be used to diagnose leaks in the fuel system.

Automotive fuel system leak testing

An alternative fuel vehicle having a fuel economy control module with associated logic that allows the vehicle to operate in a fuel economy mode based on a desired fuel economy preference. The fuel economy control logic is in electrical communication with a vehicle system controller (VSC) and may be integrally formed as a sub-module within the VSC. A fuel economy control switch controlled by the fuel economy control logic toggles between an on and an off position to enable or disable a fuel economy mode. A fuel economy control selector allows a user to select a desired fuel economy mode preference once the fuel economy control switch is on. The fuel economy mode selected represents a predefined desired fuel economy preference such as a distance per amount of fuel consumed, or alternatively, a percentage of a balance between a fuel economy operation and a fuel performance operation.
