Abstract
A multilayered fuel tank (10) for a motor vehicle is disclosed having a fuel tank body (32) for holding liquid and vapor fuel comprising a bottom wall (46), side walls (45) and a top wall and a plurality of fuel tank components (35) located on the top wall and seams (37) located on the side walls. A tank cover (36) is connected to the fuel tank body to define a vapor collection chamber (34). The tank cover encapsulates the top wall and the fuel tank components and seams thereby trapping any fuel vapors that may escape from the tank body, the fuel tank components and the seams. Also disclosed is a method of making the multilayered fuel tank and a method of preventing fuel vapors from escaping from a fuel tank to the environment.
Claims17
A multilayered fuel tank for a motor vehicle, comprising:
- (a) a fuel tank body for holding liquid and vapour fuel comprising a bottom wall, side walls and a top wall;
- (b) a plurality of fuel tank components located on the top wall and scams located on the side walls;
- and
- (c) a tank cover connected to an upper portion of the fuel tank body and defining a vapour collection chamber around the upper portion of the fuel tank, the tank cover protecting and encapsulating the top wall and the fuel tank components and seams thereby trapping any fuel vapours that escape from the tank body, the fuel tank components and the seams.
An accessory for a motor vehicle fuel tank comprising a bottom wall, side walls, a top wall, seams and a plurality of fuel tank components located on the top wall, the accessory comprising:
- a tank cover for connection to an upper portion of the fuel tank to define a vapour collection chamber around the upper portion of the fuel tank, the tank cover protecting and encapsulating the top wall, the fuel tank components ad the seems thereby trapping any fuel vapour that may escape from the tan body, the fuel tank components and the seams during use of the fuel tank.
A method of making a multilayered fuel tank for preventing the escape of fuel vapour to the environment, the method comprising:
- (a) providing a fuel tank body for holding liquid fuel and vapour comprising a bottom wall, side walls and a top wall mud a plurality of fuel tank components located on the top wall and scans located on the side walls;
- and
- (b) connecting a tank cover to an upper portion of the fuel tank body, the tank cover defining a vapour collection chamber around the upper portion of the fuel tank and protecting and encapsulating the top wall and the fuel tank components and seams thereby trapping any fuel vapours that may escape from the tank body, the fuel tank components and the seams when in use.
A method of preventing fuel vapour from escaping from a fuel tank for motor vehicles to the environment, comprising:
- (c) providing a fuel tank body for holding liquid fuel and vapour comprising a bottom wall, side walls and a top wall, and a plurality of fuel tank components located on the top wall and seams located on the side walls;
- (d) connecting a tank cover to an upper portion of the fuel tank body, the tank cover defining a vapour collection chamber around the upper portion of the fuel tank and protecting and encapsulating the top wall and the fuel tank components and seams thereby trapping any fuel vapours that may escape from the tank body, the fuel tank components and the seams;
- and
- (e) directing the trapped fuel vapours through a charcoal cannister filter to the motor vehicle engine for combustion.
