Definitions

  • This invention relates to a fuel tank.
  • the liquefied fuel In an internal combustion engine that uses liquefied fuel, the liquefied fuel is stored in a tank. However, when the temperature is elevated, the liquefied fuel is gasified to elevate the pressure in the tank which may cause the tank to burst. Therefore, for example, the ratio of gas space to the whole internal volume of the tank with liquefied petroleum gas (LPG) must not be more than 85 percent, according to the Japanese standard for handling LPG automobiles.
  • LPG liquefied petroleum gas
  • a space of a predetermined ratio must remain in the fuel tank that stores the liquefied fuel after the tank has been filled with liquefied fuel.
  • Patent literature (PTL) 1 discloses a technique that utilizes a liquid surface sensor.
  • PTLs 2 and 3 relate to the fuel tanks having complex structures.
  • a fuel tank wherein the fuel tank is of a form in which a number of cylindrical containers are arranged in parallel and are coupled together in a manner that the cylindrical containers neighboring each other share common partitioning walls, respectively; each of the partitioning walls has a passage through which the neighboring cylindrical containers are communicated with each other; the upper ends of the passages are formed leaving partly the inner partitioning walls so that the liquid will not enter into the upper parts of the cylindrical containers; and when the liquid is fed into the fuel tank, space of a predetermined volume is formed on the surface of the liquid.
  • cylindrical containers becomes the position of the upper end portions, and gas formed by the gasification of the liquefied fuel remains over the surface of the liquid. That is, a gaseous space forms on the surface of the liquid in each cylindrical container.
  • the ratio of the gaseous space to the whole internal volume of the tank has been specified for filling the storage tank with the liquefied fuel.
  • a fuel tank wherein the fuel tank is of a form in which a number of spherical containers are arranged in parallel and are coupled together in a manner that the spherical containers neighboring each other share common partitioning walls, respectively; each of the partitioning walls has a passage through which the neighboring spherical containers are communicated with each other; the upper ends of the passages are formed leaving partly the inner partitioning walls so that the liquid will not enter into the upper parts of the
  • the fuel tank is of a form in which a number of spherical containers are arranged in parallel and are coupled together to provide the fuel tank that exhibits the same effects as those of the fuel tank described in claim 1.
  • the fuel tank of claim 1 or 2 wherein the volume of the space is not less than 15 percent of the whole internal volume of the fuel tank.
  • the invention of claim 3 provides the fuel tank which when, for example, the LPG is to be stored, meets the filling ratio of not more than 85 percent specified under the Japanese standard for handling LPG automobiles.
  • the inventions described in claims provide a fuel tank of a simple structure without any special device but having a space of a predetermined ratio after the fuel tank has been filled with the liquefied fuel.

  • Fig. 3 shows the appearance of fuel tank 1 of the invention for storing a liquefied fuel such as LPG, ammonia, etc.
  • Fuel tank 1 is of a form in which a number of cylindrical containers are arranged in parallel and are coupled together.
  • Fig. 2 is a sectional view of a portion indicated by an arrow II-II in Fig. 3, and shows a portion where there is no communication passage in inner partitioning walls 8.
  • the cylindrical containers as is well known, have excellent resistance against the pressure, and the thickness of the cylindrical containers can be easily designed so as to satisfy the standards of pressure resistance. Namely, fuel tank 1 can be easily designed to satisfy the standards of pressure resistance required for the liquefied fuel.
  • Fig. 1 is a sectional view of a portion indicated by an arrow I-I in Fig. 3, and shows a portion having communication passages in inner partitioning walls 8. If the liquefied fuel is injected into fuel tank 1 through fuel inlet port 2, injected liquefied fuel 5 flows through the communication passages of the inner
  • the cylindrical containers of the fuel tank 1 do not have to be all of the same size, do not have to be arranged in parallel on the same plane, but may have a form shown, for example, in Fig. 4 (A) or 4 (B) depending on the limitations of a place on where fuel tank 1 is installed.
  • Fig. 4(A) shows an embodiment in which the cylindrical containers of fuel tank 1 have dissimilar sizes
  • Fig. 4(B) shows an embodiment in which the cylindrical containers of fuel tank 1 are not arranged on the same plane.
  • communication passages are formed in the inner partitioning walls, and upper ends 9 of the
  • fuel tank 1 When mounted on a vehicle, therefore, fuel tank 1 can have a complex shape as shown in Fig. 5.
  • Fig. 5 shows an embodiment of when fuel tank 1 is so formed as can be mounted on a vehicle astride of the driveshaft.
  • the filling ratio has been specified for storing the liquefied fuel in the storage tank.
  • the filling ratio of the LPG has been specified as not more than 85 percent.
