Abstract

A container with a tube is disclosed, which is suitable for receiving therein urea-containing liquids and which, especially due to its material properties, can easily be installed subsequently into vehicles and engines. The tube can consist of TPV.

Claims (11)

1. A kit comprising a fluid line and a container, for vehicle engines, said fluid line consists essentially of thermoplastic vulcanizate (TPV), the fluid line used for filling, venting or emptying the container, which is adapted to accommodate a urea-containing liquid, as well as for conveying the urea-containing liquid, wherein the fluid line is implemented as a monotube, has a flexural stiffness of 11 to 13 MPa and an outer to inner diameter ratio of 2:1 to 1.3:1, with a wall thickness of at least 0.7 mm to not more than 5.3 mm and wherein at least the fluid line is arranged partially within the container.

2. The kit according to claim 1 , wherein the fluid line comprises more than 90% by weight of TPV.

3. The kit according to claim 1 , wherein the fluid line has a breaking elongation of 12 to 18 MPa.

4. The kit according to claim 1 , wherein the fluid line comprises at least one layer, wherein at least one fluid line layer that comes into contact with the urea solution consists essentially of TPV.

5. The kit configured according to claim 1 for a selective catalytic reduction process in a vehicle engine.

6. The kit according to claim 1 , wherein said container consists essentially of TPV.

7. The kit according to claim 1 , wherein the urea-containing liquid is a urea solution.

8. The kit according to claim 1 , wherein the fluid line comprises more than 99% by weight of TPV.

9. The kit according to claim 1 , wherein the fluid line has a wall thickness of at least 1 mm to 5 mm.

10. A vehicle comprising a fluid line and a container, for an engine of the vehicle, said fluid line consists essentially of thermoplastic vulcanizate (TPV), the fluid line used for filling, venting or emptying the container, which is adapted to accommodate a urea-containing liquid, as well as for conveying the urea-containing liquid, wherein the fluid line is implemented as a monotube, has a flexural stiffness of 11 to 13 MPa and an outer to inner diameter ratio of 2:1 to 1.3:1, with a wall thickness of at least 0.7 mm to not more than 5.3 mm and wherein at least the fluid line is arranged partially within the container.

11. The vehicle according to claim 10 , wherein the container is adapted to accommodate a urea solution.
