- Fuel Dilution
- The amount of raw, unburned fuel that ends up in the crankcase of an engine.

- Fuel Injector
- Electro-mechanical device that precisely meters fuel into an internal combustion engine.
- Fuel Map
- A two-dimensional or three-dimensional series of curves storing the information regarding fuel and ignition for the engine, depending on the engine’s requirements.

- Fuel Processor
- Device used to generate hydrogen from fuels such as natural gas, propane, gasoline, methanol, and ethanol for use in fuel cells.
- Fuel Pump
- A pump used to deliver fuel to the engine.
- Fugacity
- The expression of activity for a component in a mixture of gases.
- Fulcrum
- The support on which a lever turns.
- Full Duplex
- Operational mode of a communication circuit in which each end can simultaneously transmit and receive data.
- Full Flow Filter
- A filter that, under specified conditions, filters all influent flow.
- Full Hard Temper
- In non-heat treatable alloys, it is the hardest temper obtainable by hard cold rolling.
- Full Scale Deflection
- The maximum value on the scale of an instrument.
- Full Wave Voltage Doubler
- Consists of two half-wave voltage rectifiers and is used to reduce the output ripple amplitude.
- Fullerene
- A form of carbon consisting of 60 carbon atoms bound together to make a roughly spherical buckyball.
- Fullering
- The process of hammering grooves in hot iron to spread it out thinner.
- Fully Ionized Plasma
- A plasma in which all the atoms or molecules have been ionized.
- Fulmination
- Any very rapid reaction which produces heat, light, and noise - explosions.
- Function
- A specific purpose of an entity; its characteristic action.
- Functional Group
- A substructure that imparts characteristic chemical behaviours to a molecule, for example, a carboxylic acid group.
- Fundamental
- In periodic forced vibration, the term fundamental refers to the lowest frequency component present in a harmonic train.
- Fundamental Interaction
- In the Standard Model the fundamental interactions are the strong, electromagnetic, weak, and gravitational interactions.
- Fung Yuan-Cheng
- Widely recognized as the father of biomechanics, having established the fundamentals of biomechanical properties in many of the human body′s organs and tissues.
- Fungicide
- A substance that kill fungi.
- Fungus
- A simple organism, e.g moulds, mildews, mushrooms, and toadstools.

- Fusible Plug
- A threaded metal cylinder with a hole that is sealed with a metal of low melting point that flows away if a pre-determined, high temperature is reached.
- Fusion
- The combining of light nuclei to form a heavier nucleus. Also, the complete mixing of two materials along an edge.
- Fusion Zone
- All reflections arriving at the observer's ear within 20 to 40 msec of the direct sound are integrated, or fused together, with a resulting apparent increase in level and a pleasant change of character. This is the Haas effect.
- Fuzzy Logic
- Invented by Lofti Zadeh in 1962.
