A fuel filling and vapor recovery system for a vehicle is described. The system includes: a canister that is in communication with a fuel receptacle in the vehicle to collect and filter fuel vapor; a first tube that is connected to the canister; a second tube that is connected to the fuel receptacle; and a canister box that is configured for connection to the first and second tubes. The canister box includes an upper member, and a lower member that is configured for engagement with the upper member such that a watertight seal is formed therebetween to prevent external water intrusion into the canister box. The lower member includes an integral connector that is configured for connection to the first tube to allow the fuel vapor to enter the canister box.

An apparatus comprises a passive RFID tag designed to provide information identifying at least one fuel compatible with a vehicle.

A fuel lid opener-has: a heart cam mechanism that is structured so as to, each time a lifter is push-operated via a fuel lid, cause the lifter to alternately repeat advancing-out and withdrawing, and so as to push the fuel lid open due to advancing-out of the lifter; and a locking mechanism-that can restrict operation of the heart cam mechanism. At the locking mechanism, a time when a stopper is moved by operation of a motor, and the aforementioned restricting is released, the aforementioned stopper engages with the heart cam mechanism and operates the heart cam mechanism. Due thereto, the lifter advances-out, and the fuel lid is pushed open.

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 vehicle fueling control system according to an exemplary aspect of the present disclosure includes, among other things, a fuel inlet conduit configured to receive a fuel dispensing nozzle, and a blocking assembly. The blocking assembly is configured to move back and forth between a fill blocking position that blocks airflow through a port of the fuel dispensing nozzle and a fill permitting position that permits airflow through the port of the fuel dispensing nozzle.

A fueling system for an engine includes a fuel tank, a controller, a fuel nozzle receptacle connected to the fuel tank, the fuel nozzle receptacle including a receptacle sensor configured to send a signal to the contoller indicative of whether a fuel nozzle of a fuel dispenser is received in the fuel nozzle receptacle, and an electric fill slop valve between the fuel tank and the fuel nozzle receptacle, the electric fill stop valve being, configured to be controlled to open and close in response to a signal from the controller. The controller can be configured to receive at least one of (a) a signal whether a fuel nozzle of a fuel dispenser is received in a fuel nozzle receptacle connected to the fuel tank, and (b) a signal whether a fuel level of the fuel tank is full, and to control the electric fill stop valve to close when a signal is sent to the controller that at least one of (a) the fuel nozzle is not received in the fuel nozzle receptacle when the controller is configured to receive the signal whether the fuel nozzle of a fuel dispenser is received in the fuel nozzle receptacle, and (b) the fuel level of the fuel tank is full when the controller is configured to receive the signal whether the fuel level of the fuel tank is full.

Methods and systems are provided for a filler inlet of a fuel fill line of a motorized vehicle. In one example, a filler inlet includes a fuel/air separation chamber extending at an angle relative to an opening of the filler inlet, with the opening adapted to receive a fuel nozzle. Fuel may be guided from the fuel nozzle toward a curved wall of the fuel/air separation chamber by a flow guide, and the fuel may separate from entrained air within the fuel/air separation chamber.

An opening device for a urea water inlet may include a first body configured to be provided on an external side of an inlet of a urea filler neck; a second body disposed at an upper end portion of the first body with a ventilation gap between the first body and the second body, and provided with an internal space to be disposed above the inlet; a cover disposed at an upper end portion of the second body, and configured to receive a force to open the internal space of the second body; an opener provided in the second body, and configured to hold the cover at the upper portion of the second body when the cover is configured to close the internal space, and to release holding of the cover when being pressed toward an interior of the second body; and a membrane disposed between the first body and the second body to pass only air therethrough while covering the ventilation gap.

In a fuel port forming portion that forms a fuel port, a portion of a peripheral wall located on a perpendicular lower side when a fuel supply device is in a mounting posture of being mounted to a vehicle formed as a convex drain groove from a corner portion at which an insertion-side open/close member for opening/closing the fuel port makes contact with an open base portion of the fuel port to an open end side of the fuel port. The drain groove is inclined in a horizontal direction such that the open end side of the fuel port is located closer to the perpendicular lower side than a corner portion side when the fuel supply device is in the mounting posture, to thereby improve draining function of the drain groove provided to the fuel port.

A capless filler pipe closure is provided for a tank filler pipe. The capless closure permits a fuel pump nozzle to be inserted into the tank filler pipe without first removing a fuel cap from the outer end of the tank filler pipe.
