Glossary “variable DC voltage generator” Definition:
Zirconia oxygen sensor is a galvanic battery that can generate a voltage of 100 to 900 millivolts in response to the amount of oxygen in the exhaust.
variable capacitor
Glossary “variable capacitor” Definition:
Capacitor whose capacitance can be adjusted by rotating a shaft or crew.
variable aperture carburetor
Glossary “variable aperture carburetor” Definition:
Term used for variable venturi carburetor.
variable
Glossary “variable” Definition:
Changeable.
VAPS
Glossary “VAPS” Definition:
Variable Assist Power Steering
vaporize
Glossary “vaporize” Definition:
To change of a solid or liquid into a vapor.
vaporization
Glossary “vaporization” Definition:
Process of turning a liquid, such as gasoline, into a vapor which is often accomplished after the atomized fuel leaves the carburetor or injector.
vapor/liquid separator
Glossary “vapor/liquid separator” Definition:
Part of the EVAP emissions control system that prevents liquid (fuel) from flowing through the vent line to the charcoal canister.
vapor/fuel separator
Glossary “vapor/fuel separator” Definition:
Term used for vapor/liquid separator.
vapor saver system
Glossary “vapor saver system” Definition:
Term used for vapor recovery system.
vapor return line
Glossary “vapor return line” Definition:
Hose or line used to carry fuel vapor from the fuel pump or the liquid vapor separator back to the fuel tank.
vapor recovery system
Glossary “vapor recovery system” Definition:
1). Part of the EVAP emissions control system that prevents fuel vapors from escaping to the atmosphere by trapping them in the charcoal canister to be drawn into the engine and burned when the engine is running. 2). The provisions of a fuel nozzle that prevent fuel vapors from entering the atmosphere when a vehicle is being fueled.
vapor lock
Glossary “vapor lock” Definition:
Condition in carbureted engines where excessive heat has caused the fuel in the fuel line or fuel pump to boil, blocking the flow of fuel to the carburetor and preventing the engine from running or starting.
vapor liquid ratio
Glossary “vapor liquid ratio” Definition:
Measurement of the ratio of vapor to liquid at a given temperature used to help determine a gasoline’s tendency to contribute to vapor lock in an automotive fuel system.
vapor lines
Glossary “vapor lines” Definition:
Lines used to carry gas or vapor.
vapor
Glossary “vapor” Definition:
A gaseous form of matter.
vanes
Glossary “vanes” Definition:
Specifically designed and positioned fins that direct or redirect fluid flow inside the torque converter.
vane pump
Glossary “vane pump” Definition:
Pump having small vanes in an elliptically shaped housing.
vane airflow meter
Glossary “vane airflow meter” Definition:
Sensor with a movable vane, connected to a potentiometer, calibrated to measure the amount of air flowing through the sensor. The output signal is sent to the processor which then translates the information into the amount of air flowing into the engine.
vane air temperature
Glossary “vane air temperature” Definition:
Sensor located in the vane airflow meter which senses the temperature of the air flowing into the engine. Changes in temperature result in changes in the resistive element of the sensor.
