A fuel tank system for a vehicle includes a fuel tank, a fuel supply passage, a canister, an evaporated fuel gas supply passage, a communication passage, a backflow prevention device, first and second pressure measurement devices, and a control device. The fuel tank stores fuel supplied by the fuel supply passage. The canister adsorbs evaporated fuel gas generated in the fuel tank and supplied through the evaporated fuel gas supply passage. The backflow prevention device is provided in a pipe line of the fuel supply passage, and prevents a backflow of the fuel from the fuel tank. The first and second pressure measurement devices respectively measure pressures in the fuel supply passage and the evaporated fuel gas supply passage. The control device diagnoses the communication passage as being blocked when a difference between pressure values measured by the first and second pressure measurement devices exceeds a predetermined value.

A vehicle safety system is for preventing child abandonment in a vehicle. The vehicle safety system may include a controller coupled to a flow sensor, a temperature sensor, and a seat sensor. The controller may be configured to detect when the vehicle is in a fueling state based upon the flow sensor, detect occupancy of a child safety seat based upon the seat sensor, and detect when a driver side door is in an open state based upon a driver side door sensor in the vehicle. The controller may be configured to when the driver side door has entered the open state, when the child safety seat is occupied, and when the vehicle does not enter the fueling state within a time period, then cause the vehicle to enter an alert state.

A tank closure that includes a first tank closure member, a second tank closure member, and a bias member having a spring force to brace the second tank closure against the first tank closure member. The first tank closure member has a first stop member, while the second tank closure member has a second stop member. The second tank closure member is flexibly mounted in an axial direction relative to the first tank closure member, the second tank closure member. The second stop member, in a closed position of the tank closure, forms a mechanical stop relative to the first stop member to prevent axial movement of the second tank closure member relative to the first tank closure member against the spring force of the bias member.

This driving device for energy replenishment port visor member includes: a visor member which advances/retracts between an advanced position for covering, from above, a replenishment port exposed at a vehicle-body-side opening and used for replenishing a vehicle with energy, and a retracted position where the visor member is retracted from above the replenishment port; a visor driving unit which advances/retracts the visor member between the advanced position and the retracted position; a gun connection detection unit which detects whether or not an energy replenishment gun is connected to the replenishment port; and a control unit which causes the visor driving unit to execute advancing-driving for advancing the visor member from the retracted position to the advanced position, when the gun connection detection unit has detected that the energy replenishment gun is connected to the replenishment port in a state in which the visor member is at the retracted position.

A fluid port assembly includes a tube configured for positioning with a fluid container to provide access to a fluid contained in the fluid container. The tube includes at least one annular tube recess. The at least one annular tube recess forms a plurality of inner tube surfaces extending circumferentially within the tube. The assembly includes a plug configured for positioning inside the tube to releasably seal the fluid container and contain the fluid within the fluid container. The plug includes at least one annular plug protrusion, and the at least one annular plug protrusion forms a plurality of outer plug surfaces extending circumferentially around the plug. The plurality of inner tube surfaces of the tube interfaces with the plurality of outer plug surfaces of the plug to seal the fluid container.

An air filter device includes an air filter and a filter case having a filter housing for housing the air filter. The filter case has a pipe part enclosing an outer circumference of a second end of a filler pipe. The second end of the filler pipe defines a fuel filler opening and is opposite to a first end of the filler pipe connected to a fuel tank of a vehicle. A distance between the pipe part and the fuel filler opening is less than a distance between the filter housing and the fuel filler opening. The pipe part is configured to be inserted into a fixed member fixed to a vehicle body. The pipe part has a flange that extends radially outward from the pipe part and is spaced apart from the filter housing in an axial direction.

A refueling adapter for an alternative fuel vehicle includes a first filling port that is fluidly coupled to an inlet nozzle of a fuel tank of the alternative fuel vehicle. The first filling port is configured to fit an inlet nozzle of a first dispensing type. A second filling port fluidly coupled to a dispenser nozzle of an alternative fuel dispenser. The second filling port is configured to fit a dispenser nozzle of a second dispensing type, the second dispensing type being different from the first dispensing type. An adapter controller is configured to communicate with a vehicle fueling system of the alternative fuel vehicle and a valve providing a fluid connection between the first filling port and the second filling port and is operated by the adapter controller to selectively open and close the fluid connection.
