Abstract
A vehicle fuel tank arrangement is provided for a fuel that includes at least a first fluid and a second fluid. The tank arrangement includes a tank and a partition wall arranged inside the tank in order to create at least a first compartment for storing the first fluid and a second compartment for storing the second fluid. The position of the partition all inside the tank can be changed to set the volume of the first compartment and the second compartment to predetermined values.
Claims16
A vehicle fuel tank arrangement for a fuel comprising at least a first fluid and a second fluid, the tank arrangement comprising:
- a tank;
- and
- a partition wall arranged inside the tank in order to create at least a first compartment t for storing the first fluid and a second compartment for storing the second fluid;
- wherein the position of the partition wall inside the tank can be changed to set the volume of the first compartment, respectively the second compartment, to a predetermined value;
- wherein the vehicle fuel tank arrangement comprises an actuator which is coupled to the partition wall and which is arranged to change a position of the partition wall inside the tank to set a volume of the first compartment and a volume of the second compartment to predetermined values that are predetermined according to predicted consumptions of the first and second fluids.
A method for managing the supply of fuel to a vehicle engine, the method comprising:
- providing a vehicle fuel tank arrangement for a fuel comprising at least a first fluid and a second fluid, the tank arrangement comprising;
- a tank:
- and
- a partition wall arranged inside the tank in order to create at least a first compartment for storing the first fluid and a second compartment for storing the second fluid;
- wherein the position of the partition wall inside the tank can be change to set the volume of the first compartment, respectively the second compartment, to a predetermined value;
- wherein the vehicle fuel tank arrangement comprises an actuator which is coupled to the partition wall and which is arranged to chance a position of the partition wall inside the tank to set a volume of the first compartment and a volume of the second compartment to predetermined values that are predetermined according to predicted consumptions of the first and second fluids,
- predicting respective consumptions of the fluids contained in the fuel tank, based on at least one operational parameter, and
- before the compartments are refilled, changing the position of the partition wall according to the prediction.
