A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber, which can absorb fuel when ...
Mark talked with the driver to understand why the two hose system was used, and also why it was not implemented on the standard delivery nozzle, allowing vapors to escape from the vehicle gas tank. After the tanker driver left, Mark drew an idea for a Vapor Recovery Gasoline Nozzle and submitted it to the Chevron Station Management as an ...
If the car's own vapor recovery system is working properly, then the Stage II nozzle will only be vacuuming normal fresh air and depositing that into the gas station's underground fuel storage tanks. That ends up causing evaporation of fuel vapors into the atmosphere, because too much pressure builds up in those fuel storage tanks.
A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids, often gasoline or diesel fuel. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled ( fuel pump ) or released (pressurized gas) into an engine .
Fuel bladders are used in various fields, such as agribusiness, public works, humanitarian, military and industrial areas. Standard tanks are designed for land based use and operations, but can be used in marine settings and in aviation given proper support. Fuel bladders are also commonly used in oil spill recovery operations. [2]
A major problem with welded aluminium tanks is weld decay and metal fatigue in the seams due to vibration in service. In response to this, the company started to develop flexible fuel bladders in the early 1940s. One of the earliest examples of this was a composite flexible fuel bladder with self-sealing coatings for the Supermarine Spitfire MkIX.
A small amount of fuel in the tank leaves pumps on the floor of the tank exposed to the air-fuel mixture, and an electric pump is a potential ignition source. The explosion of a Thai Airways International Boeing 737 in 2001 and a Philippine Airlines 737 in 1990 also occurred in tanks that had a small amount of residual fuel.
