Fuel starvation occurs when a device powered by an internal combustion engine can’t access its fuel supply due to problems with the fuel delivery system, caused by blockages, leaks, or water intrusion. Regular maintenance and inspection are crucial to prevent engine failure, especially in aviation.
Fuel starvation occurs when a device powered by an internal combustion engine, especially a vehicle of some form, is unable to make use of its available fuel due to some problem with the fuel delivery system. There are a few different causes for fuel starvation, including blockages, leaks, and the intrusion of water into the fuel tank. A powered device that can’t access its fuel supply can’t work, because internal combustion engines that don’t have fuel to burn don’t work. This can be simply inconvenient if it happens to a device like a lawn mower, but can be deadly if it happens to an airplane, and quite dangerous if it happens to a car in some situations.
There are a few different factors that can lead to a lack of fuel. Unused fuel can be lost through leaks in the system that supplies fuel from the tank to the engine, resulting in an inadequate supply of fuel to the engine. A blockage in the fuel filter or another part of the fuel delivery system can also lead to a lack of fuel. If water mixes with fuel, it tends to pool at the bottom of the tank below the fuel, where it will be drawn out of the tank before the fuel. An internal combustion engine cannot run on water, so this also causes a lack of fuel.
The term “starvation of fuel” only applies to situations where the system responsible for delivering fuel to the engine is faulty. It does not refer to situations where the fuel supply actually runs out, although the consequences are generally similar. “Fuel run out” is the term used to describe situations in which a vehicle or other powered device consumes all of its fuel and is rendered inoperative because there is no more fuel to use.
Aviators should pay special attention to the problem of lack of fuel, because the consequences of engine failure in mid-flight can be quite serious. While proper planning can usually prevent fuel depletion, it can do little to prepare for or prevent fuel starvation. Regular maintenance, inspection, and testing of engines and fuel systems are the best ways to ensure that fuel actually reaches the engine. It’s not particularly common for aircraft fuel supply systems to fail to provide fuel for engines, but it only takes one failure of such a system to endanger the lives of everyone on the plane.
