The word "defuel" is spelled with the letters D-E-F-U-E-L. According to IPA phonetic transcription, it is pronounced as /diːˈfjuːl/.

The term "defuel" refers to the process of removing or reducing the amount of fuel present in a vehicle, aircraft, or machinery. It involves the deliberate action of extracting fuel to decrease the overall quantity of combustible material within a system. Defueling is commonly performed for various reasons, such as during maintenance, repairs, storage, or in emergency situations.
In the context of automobiles or other modes of transportation, defueling typically involves draining the fuel tank of its contents. This can be accomplished through different methods, including siphoning, using specific equipment, or expelling fuel from the fuel line. Defueling is often implemented when a vehicle is being decommissioned or stored for extended periods to prevent deterioration of the fuel and potential safety hazards.
Furthermore, defueling is especially important in the aviation sector. Prior to certain maintenance activities or storage, aircraft need to undergo defueling procedures to reduce the risk of accidents, minimize fire hazards, or comply with safety regulations. This process involves extracting fuel from the aircraft's tanks by means of specialized equipment that ensures the safe removal of flammable material.
Overall, "defuel" refers to the intentional removal or reduction of fuel from a vehicle, aircraft, or machinery, typically performed to enable maintenance, storage, or mitigate potential safety risks associated with the presence of highly flammable substances.
The word "defuel" is a combination of two parts: "de-", a prefix indicating to reverse or remove, and "fuel", meaning a substance used to produce energy or power. The etymology of "fuel" can be traced back to the Old French word "foaile" or "feuaile", which referred to firewood or kindling. It evolved from Latin "focāle" meaning "fuel for a fire" or "domestic hearth". The word "defuel" itself is a modern creation used to describe the act of removing or extracting fuel from a vehicle or system, often for maintenance, repair, or decommissioning purposes.
