Encyclopedia > Fuel tank

A fuel tank is the part of an engine system in which the fuel is stored and released into the engine.

  • Filling (the fuel tank must be filled in a secure way)
  • Storage of fuel (the system must contain a given quantity of fuel and must avoid leakage and limit evaporative emissions)
  • Gauging (the remaining quantity of fuel in the tank must be measured or evaluated)
  • Venting (if over-pressure is not allowed, the fuel vapors must be managed through valves)
  • Feeding of the engine (through a pump)

Automotive

For each new vehicle a specific fuel system has to be developed, as they must optimize the empty space left by the car architecture.


Moreover, for one car model, different versions of fuel system architectures have to be developed with more or less components, depending on the type of the car, the type of fuel (gasoline or diesel), nozzle models and the region where the car will be circulating.


Two technologies are used to make fuel tanks for automobiles:

  • Plastic High density polyethylene (HDPE) fuel tanks produced through blow moulding. This technology is increasingly used as it now shows its capacity to obtain very low emissions of fuel (see Partial zero-emissions vehicle). HDPE can also allow for complex shapes to be formed, this means the tank to be mounted directly over the rear axle, saving space and improving crash safety. Initially there were concerns over the low fracture toughness of HDPE, when compared to steel or aluminium.
  • Metal (steel or aluminium) fuel tanks obtained by welding of stamped sheets. Although this technology is very good in limiting fuel emissions, it tends to be less competitive and thus less on the market.

Central locking

Cars generally include a fuel tank filler flap (also called fuel filler cap) integrated in central locking. In general, a filler is something that is used to fill gaps. ... The word Flap can refer to several things. ... A cap is a form of headgear. ... Power door locks (aka electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch. ...


Remote opening

Modern cars includes remote opening of the fuel tank fuel filler flap using an electric motor. Some expensive cars even have fuel tanks that cannot be opened by hand or by any way from the outside of the car. A motor is a device that converts energy into mechanical power, and is often synonymous with engine. ...


Reserve Tank

Sometimes called the reserve tank, a light on the instrument panel of autos typically illuminates when the fuel level dips below a certain point in the tank. There is no current standard, although some efforts are made to collect this data for all automobiles.


Aircraft

Aircraft typically use three types of fuel tanks: integral, rigid removable, and bladder.


Integral tanks are areas inside the aircraft structure that have been sealed to allow fuel storage. An example of this type is the "wet wing" commonly used in larger aircraft. Since these tanks are part of the aircraft structure, they cannot be removed for service or inspection. Inspection panels must be provided to allow internal inspection, repair, and overall servicing of the tank. Most large transport aircraft use this system, storing fuel in the wings and/or tail of the airplane.


Rigid removable tanks are installed in a compartment designed to accommodate the tank. They are typically of metal construction, and may be removed for inspection, replacement, or repair. The aircraft does not rely on the tank for structural integrity. These tanks are commonly found in smaller general aviation aircraft, such as the Cessna 172. Cessna 172RG 1964 Cessna 172E 1965 Cessna F172G 1971 Cessna 172 The early Cessna 172 Skyhawks had no rear window and featured a square fin design, like this 1957 model 1977 Cessna 172XP 1977 Cessna 172M Cessna 172R Panel of C-GLFC The Cessna 172 Skyhawk is a four-seat...


Bladder tanks are reinforced rubberized bags installed in a section of aircraft structure designed to accommodate the weight of the fuel. The bladder is rolled up and installed into the compartment through the fuel filler neck or access panel, and is secured by means of metal buttons or snaps inside the compartment. Many high-performance light aircraft and some smaller turboprops use bladder tanks.


Fuel tanks have also been implicated in aviation disasters. For example, the official explanation for the explosion and subsequent crash of TWA Flight 800 is that an explosive fuel/air mixture was created in one of the aircraft's fuel tanks. Faulty wiring then provided an ignition source within the tank, destroying the airliner. While the accuracy of the official findings is still questioned in this case, similar explosions have occurred in other aircraft. It is possible to reduce the chance of fuel tank explosions by a fuel tank inerting system. This article or section does not cite its references or sources. ... Trans World Airlines (TWA) Flight 800, a Boeing 747-131, N93119, crashed on July 17, 1996, about 20:31 EDT (00:31, July 18 UTC), in the Atlantic Ocean near East Moriches, New York. ... An inerting system is a device that attempts to increase the safety of a fuel tank, ball mill, or other sealed or closed-in tank that contains highly flammable material, by pumping nitrogen, steam, carbon dioxide, or some other inert gas or vapor into its air space in order to...


Water Supply

Water supply systems can have primary or backup power supplied by diesel-fueled generators fed by a small "day tank" and a much larger bulk storage fuel tank. [1] [2]


Safety

The proper design and construction of a fuel tank plays a major role in the safety of the system of which the tank is a part.


In automotive applications, improper placement of the fuel tank has led to increased probability of fire in collisions. Circa 1990, General Motors faced over a hundred lawsuits related to fires allegedly caused by GM's decision to place the fuel tanks in its pickup trucks outside the protection of the vehicle's frame [2]. Ford's Ford Pinto also sparked controversy for putting the gas tank in a poorly reinforced area which can cause deadly fires and explosions if the car got into a rear end collision, costing Ford $125 million. In 1993, as one of these lawsuits resulted in a US$101 million judgement against GM (later overturned), the television show Dateline NBC created its own controversy by staging an example of the failures. When it was discovered that Dateline's consultants had rigged the truck with incendiary devices in order to guarantee a fire, GM filed a defamation suit, and several NBC employees were fired.
