Glossary “variable voltage choke” Definition:
Solid state relay which is duty cycle modulated by the processor to effect variable choke control depending on the choke degree required.

Glossary “variable reluctance sensor (VRS)” Definition:
Electrical device that generates current when the magnet reluctor moves in relation to the location of the coil. The amount of current produced, varies as the reluctor move towards and then awat from the coil.

Glossary “variable resistor” Definition:
Resistor that provides for an infinite number of resistance values within a specific range, such as a rheostat or potentiometer.

Glossary “variable speed fan” Definition:
Fan having a fluid-filled or thermostatic-actuated clutch that senses the temperature of the air coming through the radiator and adjusts its speed accordingly.

Glossary “variable venturi carburetor” Definition:
A carburetor having an aperture that increases or decreases in size as controlled by intake manifold vacuum and engine load.

Glossary “variable rate spring” Definition:
Spring that increasingly resists deflection as the load is increased, such as a coil spring having its coils closer together at one end, or in a single-leaf spring that is thinner near the ends.

Glossary “variable ratio power steering” Definition:
Power steering system in which the response of the wheels, varies the ratio according to how much the steering wheel is turned.

Glossary “variable ratio steering” Definition:
Power steering system that varies the steering ratio at different vehicle speeds.

Glossary “variable reluctance” Definition:
Process of passing a varying magnetic field through wire windings and inducing a voltage.

Glossary “variable pitch stator” Definition:
Torque converter design for transmissions used in off-highway, special-equipment applications.

Glossary “variable rate coil spring” Definition:
Spring having an average spring rate based on load at a predetermined deflection in a variety of wire sizes and shapes.

Glossary “variable pitch spring” Definition:
A valve spring with unevenly spaced coils.

Glossary “variable orifice steering system” Definition:
Additional power steering assistance is provided during low speed cornering and parking; normal power steering assistance is provided at higher speeds.

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.

Glossary “variable displacement engine” Definition:
An engine designed so that displacement can be altered by activating and deactivating cylinders.

Glossary “variable displacement pump” Definition:
A pump that automatically regulates output volume of fluid based on the needs of the transmission.

Glossary “variable dwell” Definition:
In an electronic ignition system, when at low rpm, the dwell is shorter and at higher rpm it is longer.

Glossary “variable aperture carburetor” Definition:
Term used for variable venturi carburetor.

Glossary “variable capacitor” Definition:
Capacitor whose capacitance can be adjusted by rotating a shaft or crew.
