Abstract
Official abstract text for this publication.
A fuel storage system may be configured for a vehicle and may include a fuel tank, at least one inflatable bladder extending inside the tank, and at least one heat storage member, extending inside the tank, comprising a phase change material having a melting point in a range of from 18 to 40° C. The heat storage member may be attached to a bottom wall of the tank and/or attached to the bladder. The system may include several heat storage members.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A fuel storage device configured for a motor vehicle, the device comprising: a fuel tank; an inflatable bladder extending inside the fuel tank; and a first heat storage member, extending inside the fuel tank, comprising a phase-change material with a melting point in a range of from 18 to 40° C., wherein the first heat storage member is attached to the inflatable bladder. 2 . The device of claim 1 , further comprising: a second heat storage member, wherein the second heat storage member is attached to a bottom wall of the tank. 3 . The device of claim 1 , further comprising: a second heat storage member, wherein the second heat storage member is constructed as a floating body configured to float on a fuel in the tank. 4 . The device of claim 1 , further comprising: further heat storage members. 5 . The device of claim 4 , wherein the further heat storage members are attached to a support plate configured to float on a fuel in the tank. 6 . The device of claim 1 , wherein the phase-change material has a melting point in a range of from 20 to 30° C. 7 . The device of claim 1 , wherein the phase-change material comprises calcium chloride hexahydrate, octadecane, cyclohexanol, and/or a glycerine derivative. 8 . The device of claim 1 , further comprising: a second heat storage member. 9 . The device of claim 1 , wherein the phase-change material comprises calcium chloride hexahydrate. 10 . The device of claim 1 , wherein the phase-change material comprises octadecane. 11 . The device of claim 1 , wherein the phase-change material comprises cyclohexanol. 12 . The device of claim 1 , wherein the phase-change material comprises a glycerine derivative. 13 . The device of claim 1 , further comprising: further heat storage members, wherein the further heat storage members are attached to the inflatable bladder.
