Abstract
A system includes a fuel tank and a fuel vapour cooling arrangement connected to the fuel tank. The fuel vapour cooling arrangement is arranged to receive fuel vapour evaporated from the fuel in the fuel tank. In the fuel vapour cooling arrangement, the evaporated fuel is condensed into liquid fuel. The fuel vapour cooling arrangement is arranged outside of the fuel tank. A valve is arranged between the fuel tank and the fuel vapour cooling arrangement to control the opening and closing of the connection between the fuel tank and the fuel vapour cooling arrangement.
Claims14
A system for handling fuel vapour in a fuel tank of a vehicle, wherein the system comprises:
- a fuel tank,
- a fuel vapour cooling arrangement connected to the fuel tank, arranged to receive fuel vapour evaporated from fuel in the fuel tank, in which the evaporated fuel is condensed into liquid fuel, wherein
- the fuel vapour cooling arrangement is arranged outside of the fuel tank, and
- a valve is arranged between the fuel tank and the fuel vapour cooling arrangement to control the opening and closing of a fuel vapour cooling arrangement connection between the fuel tank and the fuel vapour cooling arrangement, wherein the system is configured for performing:
- condensing the evaporated fuel by cooling the fuel vapour and by pressurizing either a cooling medium in the fuel vapour cooling arrangement or by pressurizing the fuel vapour.
A method for handling fuel vapour in a fuel tank of a vehicle, wherein a fuel vapour cooling arrangement is connected to the fuel tank and arranged outside of the fuel tank, wherein the method comprises:
- receiving fuel vapour in the fuel vapour cooling arrangement evaporated from fuel in the fuel tank,
- condensing the fuel vapour to liquid fuel in the fuel vapour cooling arrangement,
- controlling the opening and closing of a fuel vapour cooling arrangement connection between the fuel tank and the fuel vapour cooling arrangement by means of a valve arranged between the fuel tank and the fuel vapour cooling arrangement, and
- condensing the evaporated fuel by cooling the fuel vapour and by pressurizing either a cooling medium in the fuel vapour cooling arrangement or by pressurizing the fuel vapour.
