摘要： 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 controller 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.

摘要： A vehicle including a pressurized liquid fuel system includes a first pressurized liquid fuel tank arrangement, a second pressurized liquid feel tank arrangement, and a balancing conduit open to a first fuel tank and to a second fuel tank at least one of above a maximum liquid level of the first fuel tank and a maximum liquid level of the second fuel tank and below a minimum liquid level of the first fuel tank and a minimum liquid level of the second fuel tank. A first return line and a second return Sine to the first and second fuel tanks are configured such that a pressure drop across the first, return line from a pressurized liquid fuel circulation system to the first fuel tank is adapted to be the same as a pressure drop across the second return line from the pressurized liquid fuel circulation system to the second fuel tank. Methods for operating a pressurized liquid fuel system are also disclosed.
