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.
Claims16
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;
- 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;
- and
- a vehicle fuel pump coupled between the outlet port of the fuel pump input selector and the tank outlet port and operable to pump fuel to the tank outlet port from one of the source tank or the in-tank fuel pickup.
A fuel system for a vehicle, the fuel system comprising:
- a refueling connector configured for receiving fuel from a storage tank;
- a vehicle fuel tank configured to store fuel;
- a fuel pump input selector including a first inlet port configured for receiving fuel from the refueling connector, a second inlet port configured for receiving fuel from the vehicle fuel tank, 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;
- and
- a vehicle fuel pump coupled to the outlet port of the fuel pump input selector and operable to pump fuel from one of the storage tank or the vehicle fuel tank.
