Abstract
Official abstract text for this publication.
Fuel tank ( 1 ) having: a wall ( 12 ) defining an internal volume ( 20 ) of the tank, and a temperature sensor ( 4 ) located inside the internal volume of the tank and at least partially enveloped with a material ( 21 ) having a thermal diffusivity comprised between 2×10 −7 and 2×10 −5 m 2 /s at 20° C. The temperature sensor measure an internal tank temperature, such as a vapor dome temperature.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel tank comprising: a wall defining an internal volume of the fuel tank, the wall having a top portion, a down portion, and a lateral portion, and a temperature sensor located inside the internal volume of the fuel tank and attached to an inner side surface of the top portion of the tank wall, the temperature sensor being at least partially enveloped with a material having a thermal diffusivity comprised between 2×10 −7 and 2×10 −5 m 2 /s at 20° C., wherein the temperature sensor has a thermal inertia and the material has a thermal inertia according to the following formula: 1 3 < thermal inertia of the temperature sensor thermal inertia of the temperature sensor + thermal inertia of the material < 1. 2. The fuel tank according to claim 1 , wherein the material has a thickness comprised between 0.1 and 20 mm. 3. The fuel tank according to claim 1 , wherein the temperature sensor is totally enveloped with the material. 4. The fuel tank according to claim 1 , wherein the material forms a coating enveloping at least partially the temperature sensor. 5. The fuel tank according to claim 1 , wherein the material forms a housing for housing at least partially the temperature sensor. 6. The fuel tank according to claim 1 , wherein the material is a steel. 7. The fuel tank according to claim 1 , wherein the material is a stainless steel. 8. The fuel tank according to claim 1 , wherein the temperature sensor is attached to the fuel tank via a support. 9. The fuel tank according to claim 1 , wherein the temperature sensor is welded to the fuel tank. 10. The fuel tank according to claim 1 , further comprising an electrical wire and an electronical board, wherein the electrical wire connects the temperature sensor to the electronical board, and at least a portion of the electrical wire is contiguous to the temperature sensor being enveloped with the material. 11. A vehicle comprising a fuel tank according to claim 1 . 12. A fuel tank comprising: a wall defining an internal volume of the fuel tank, a temperature sensor located inside the internal volume of the fuel tank and at least partially enveloped with a material having a thermal diffusivity comprised between 2×10 −7 and 2×10 −5 m 2 /s at 20° C., an electrical wire, an electronical board, and a pressure sensor having a pressure port forming a hole through the wall of the fuel tank or the pressure sensor having a pressure port, wherein the temperature sensor is attached to the pressure port of the pressure sensor, wherein the electrical wire connects the temperature sensor to the electronical board through the pressure port. 13. A fuel tank comprising: a wall defining an internal volume of the tank, the wall having a top portion, a down portion, and a lateral portion, a temperature sensor located inside the internal volume of the tank and at least partially enveloped with a material having a thermal diffusivity comprised between 2×10 −7 and 2×10 −5 m 2 /s at 20° C., wherein the temperature sensor has a thermal inertia and the material has a thermal inertia according to the following formula: 1 3 < thermal inertia of the temperature sensor thermal inertia of
