22Fuel mass fraction — In combustion physics, fuel mass fraction is the ratio of fuel mass flow to the total mass flow of a fuel mixture. If an air flow is fuel free, the fuel mass fraction is zero; in pure fuel without trapped gases, the ratio is unity. [cite book |… …
23Fuel oil — An oil tanker taking on bunker fuel. Fuel oil is a fraction obtained from petroleum distillation, either as a distillate or a residue. Broadly speaking, fuel oil is any liquid petroleum product that is burned in a furnace or boiler for the… …

25Fuel reserve — In motorcycles and cars, fuel reserve is the extra fuel reserved by the manufacturer in the fuel tank of a car or motorcycle before the main fuel capacity runs out.In motorcycles, when the main fuel runs out, the rider has to manually turn the… …
26flow divider — A component in the fuel control system of a gas turbine engine that routes all the fuel to the primary nozzles when starting the engine and when RPM are low. When the engine speed builds up, the flow divider opens a passage to send a majority of… …
27fuel injection — A form of a fuel metering system for a reciprocating engine that injects fuel directly into the cylinder rather than mixing it with air before it is taken in through the intake valve. The two types of fuel injection systems are the direct… …
28fuel cock — A tap which can allow or restrict the flow of gasoline from the gas tank to the carburetor. An essential item on a motorcycle with gravity feed (i.e., no fuel pump) because if the fuel cock is left on after the engine is shut down, there is the… …
29fuel cut-off switch — A control device which manually or automatically turns off the flow of fuel. Also see inertia fuel cut off switch …
30fuel cock — device for turning the flow of fuel on or off …
