VapourMinute airborne droplets of a liquid or liquid that has been heated to a gas state. |
Vapour LockVapour formation in a fuel line caused by heat. The effect is similar to an air lock and acts to prevent fuel delivery. To clear the vapour lock the fuel line must be bled or allowed to cool. |

Variable Choke CarburettorA carburettor with a variable diameter venturi (choke tube). The variable diameter is obtained by inlet manifold vacuum being applied to one side of a diaphragm or piston and atmospheric pressure to the other side. This arrangement produces a constant depression and relatively accurate fuel metering. |
Variable ResistorA resistor that can have its value changed manually. |
