The Purpose of a Fuel System
A fuel system purpose is to store, transfer, and then to mix the fuel with air. The function of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air, vaporized, and burned to produce energy.
As everyone knows, an internal combustion engine needs fuel to operate. Fuel is delivered to the engine by means of the fuel system. The fuel system must be self-contained and efficient so that it will properly energize the engine and will take up as little space as possible necessary to its mechanical functioning. An internal combustion engines fuel system is, literally, the heart of the engine.
All internal combustion engines need three things to run that is Air, Fuel and Spark. The fuel system is critical in storing and delivering the aviation fuel to the engine that is needed for it to run. Think of it as your vascular system, with a heart (fuel pump), veins (fuel lines) and kidneys (filter). A failure in any of these fuel system components has the same devastating effects as in your body. Proper maintenance of an engine's fuel system is crucial to economically and ecologically efficient operation.
The fuel, which can be either gasoline or diesel, is stored in a fuel tank. For most aircraft, we use Aviation fuel, which is a specialized type of petroleum-based fuel, used to power aircraft. It is generally of a higher quality than fuels used in less critical applications, such as heating or road transport, and often contains additives to reduce the risk of icing or explosion due to high temperature, among other properties. We must choose the specific fuel that is used for that specific kind of aircraft.
The ATA (Air Transport Association) Chapter for fuel system is in ATA 28. Here it is indicated the general use, storage, distribution of fuel to the engine combustion system.
