Fuel Tanks

Fuel tanks can be any safe container for flammable liquids. It is important that it is a safe container as containing fuel in a confined space can be a very dangerous thing.

More specifically, fuel tanks refer to a part of an engine system that stores fuel and propels or releases it into the engine. As such fuel tanks are a part of an integrated into a larger system and are not merely passive containers of fuel. They are an active component of the system.

Fuel tanks have several specific qualities. As a storage facility it must avoid any leakage and limit evaporation. This is not just to avoid wasting money but also a safety feature. Have fuel, a flammable substance, leaking out of its container is very dangerous. Even fumes from evaporation can ignite and are an even bigger hazard than leaks. With this being the case, it is as important that fuel tanks can be filled in a secure was without the possibility of sparks being created. It only takes one spark to cause the content of fuel tanks to ignite and cause an explosion.

On a practical level, fuel tanks must have a method of determining the level of fuel in the tank. With fuel tanks in an engine system it is not always possible, it is probably never possible, to actually look inside the tank to see for oneself how much fuel is in there. A system of measurement needs to be in place.

While it is important that fuel tanks must not allow evaporation, it is also important that vapour must not be allowed to collect within the fuel tank. A build up of vapour is dangerous and could lead to an explosion, so fuel tanks must have a system of venting vapour safely.
