Abstract
A vehicle has a fuel system that includes a controller that determines when the vehicle is in a refuel mode or a run mode based on a connection of a refuel nozzle to a vehicle connection of the vehicle. The controller controls a fuel pump input selector, a vehicle fuel pump, and a fill/run fuel selector such that fuel is pumped from a storage tank external to the vehicle into a vehicle fuel tank by way of the vehicle fuel pump in the refuel mode, and fuel is pumped to an engine of the vehicle from the vehicle fuel tank by way of the vehicle fuel pump in the run mode.
Claims20
A fuel system for a vehicle, the fuel system comprising:
- a vehicle fuel tank comprising:
- a tank inlet port configured to receive fuel from a source tank, and
- a tank outlet port configured to supply fuel to an engine supply line of the vehicle;
- an in-tank fuel pickup configured to receive fuel from the vehicle fuel tank;
- and
- a fuel pump input selector including a first inlet port configured for connection to the tank inlet port, a second inlet port coupled to the in-tank fuel pickup, and an outlet port, the fuel pump input selector configured to selectively direct fuel to the outlet port from the first inlet port during a refuel mode or from the second inlet port during a run mode.
A refueling system, comprising:
- a refueling appliance, the refueling appliance comprising:
- a storage tank configured to store fuel, and
- a refueling nozzle coupled to the storage tank and configured to couple to a refueling connector to dispense fuel from the source tank to a fuel tank of a fuel system, wherein the fuel system comprises a fuel pump input selector including a first inlet port configured to receive fuel from the refueling connector, a second inlet port configured to receive fuel from the fuel tank, and an outlet port,
- wherein the fuel pump input selector is configured to selectively direct fuel to the outlet port from the first inlet port during a refuel mode or from the second inlet port during a run mode.
A fuel system for a vehicle, the fuel system comprising:
- a vehicle fuel tank configured to store fuel, the vehicle fuel tank comprising:
- a tank inlet port configured to receive fuel from a source tank,
- a tank outlet port configured to supply fuel to an engine supply line of the vehicle, and
- a tank fill port configured to receive fuel from the engine supply line of the vehicle;
- a fill/run fuel selector having a receiving port coupled to the tank outlet port, a first outlet port coupled to the tank fill port, and a second outlet port coupled to the engine supply line of the vehicle,
- wherein the fill/run fuel selector is configured to selectively direct fuel from the receiving port to the tank fill port during a refueling mode or to the engine supply line during a run mode.
