DICTIONARY OF AUTOMOTIVE TERMS - "Ve"

VE:

Value engineering.

VECI:

Acronym for Vehicle Emission Control Information which is on a decal placed on the windshield of a car.

Vector:

A physical quantity which has direction such as force and momentum.

Vector potential:

Potential postulated in electromagnetic field theory. Space differentiation (curl) of the vector potential yields the field. Magnetic vector potential is due to electric currents, while electric vector potential is assumed to be due to a flow of magnetic charges.

Vee-belt:

See V-belt

Veeder root:

The brand name of a common type of odometer.

Vee engine:

A type of engine with two banks of cylinders, each set at an angle to each other (in an end view) to form a "V".

Vega:

See facel Vega

Vehicle:

1. A conveyance on wheels or runners used to carry people or goods over land (e.g., bicycle, motorcycle, car, truck, sleigh, snowmobile).
2. A binder.
3. The liquid portion of an adhesive, coating, or sealer compound consisting of the binder and volatile thinners.

V-eight:

(V-8) An engine with eight cylinders in two rows of four cylinders with a common crankshaft and shaped in the letter V

V-eight engine:

(V-8) An engine with eight cylinders in two rows of four cylinders with a common crankshaft and shaped in the letter V. It is usually smoother and more powerful than an in-line six-cylinder.The intake manifold is located inside the V. The exhaust manifold is found on each side of the engine. Before fuel economy became an important selling point, V-8 engines were found in the manjority of cars produced in North America.

Velocimeter:

Instrument that measures air speeds using a direct-reading air speed indicating scale.

Velocipede:

An early form of bicycle or tricycle propelled by thrusts of the feet against pedals.

Velocity:

1. The rate of motion in a particular direction.
2. Quickness or rapidity of motion, swiftness, speed.

Velocity joint:

See constant velocity joint.

Velocity stack:

A device mounted on the carburetor, typically made of polished or gold anodized aluminum, with or without a wire mesh filter; it looks good, provides greater air intake and increases engine performance but reduces engine life due to the intake of unfiltered or badly cleaned air

Velocity universal joint:

See constant velocity universal joint

Velodrome:

An oval track, often with wooden flooring, where bicycles race.

Vena contracta:

The point of lowest-pressure and highest velocity that's located 0.030 inch below the venturi's throat (minimum diameter). The center of the discharge nozzle or the trailing edge of the booster venturi is placed at the vena contracta

V engine:

See V-type engine.

V-engine:

See V-type engine.

Vent:

1. A small aperture designed to provide an outlet from a confined space or a inlet into it. Air vents (which are also used for heating and are sometimes called "louvres") are usually situated at the top of the dashboard pointing upward toward the windshield), in the center of the dashboard (directing the airflow out into the middle of the passenger compartment), on each side of the dashboard (sending the air back along the sides to the rear of the vehicle), and in the center underneath the dashboard (directing air into the front footwells).
2. A small triangular window for letting air into the passenger compartment.
3. To expel through a vent; e.g., when bleeding air (through a vent valve or bleed screw) out of a diesel fuel system alter running out of fuel.

Vented brake disc:

A brake disc that has cooling passages cast or drilled between its friction surfaces.

Ventilate:

To provide with (fresh) air

Ventilated brakes:

A brake setup which allows air to enter to cool the rotor and caliper.

Ventilated discs:

Two discs in a disc brake system separated by ribs and channels to allow cooling air to disperse the heat between the discs

Ventilated rotor:

A disc brake rotor whose friction surfaces are separated by cooling fins.

Ventilation:

1. A provision of a free or controlled circulation of air.
2. Forced airflow, by design, between one area and another.

Also See:
closed crankcase ventilation
crankcase ventilation
flow-through ventilation
positive crankcase ventilation system
positive crankcase ventilation

Ventilation slot:

A series of gaps in the wheel disc which allow the passage of air to assist brake cooling

Ventilation system:

See positive crankcase ventilation system

Venting:

The act of perforating a textile bias ply tubeless tire above the beads during retreading. Thus air bleeding through the calendering can escape without forming air pockets between plies.

Ventiport:

See porthole

Vent port:

See compensating port

Vent slot:

A series of gaps in the wheel disc which allow the passage of air to assist brake cooling

Venture:

See joint venture

Venturi:

That part of a tube, channel, pipe, etc., so tapered as to form a smaller or constricted area. A liquid, or a gas, moving through this constricted area will speed up and as it passes the narrowest point, a partial vacuum will be formed. The taper facing the flow of air is much steeper than the taper facing away from the flow of air. The venturi principle is used in the air horn throat of the carburetor.
Also See:
air-valve carburetor
carburetor venturi
variable venturi.

Venturi tube:

A short tube with a constricted passage that increases the velocity and lowers the pressure of a fluid conveyed through it. The venturi, or "choke tube," in a carburetor is used to suck the fuel from the float chamber through a discharge nozzle (fixed jet carburetor) or main jet (variable choke carburetor) into the barrel

Venturi vacuum:

A vacuum in the venturi of a carburetor which increases with the speed of the airflow passing through it; an exception are VV carburetors

Venturi vacuum amplifier:

(VVA) used with some EGR system so that carburetor venturi vacuum can control EGR valve operation; venturi vacuum is desirable because it is proportional to the airflow through the carburetor

Vent wing:

A small triangular-shaped side window which is located in front of the main front side windows. Vent wings can be swung out into the air stream to improve ventilation inside the car. Also called wind wings.

VER:

Acronym for "Voluntary Export Restraint."

Vernier caliper:

A short graduated scale that slides along a longer graduated instrument and is used to indicate fractional parts of divisions, as in a micrometer

Vernier gauge:

A short graduated scale that slides along a longer graduated instrument and is used to indicate fractional parts of divisions, as in a micrometer

VERTAC-process:

A process in which car bodies are transported horizontally through the surface treatment plant

Vertical keel:

See center vertical keel

Vertical keiretsu:

A keiretsu system with a production-oriented close partnership between a major company (such as Toyota) and many small suppliers which work exclusively and/or constantly for their giant customer within the just-in-time concept

Vertical position:

Type of weld where the welding is done on a vertical seam and on a vertical surface.

Vertical tire clearance:

The distance between the top of the tread and some part of the vehicle closest above it, after subtracting the axle stop clearance and any increase in tread depth from me existing tire.

Vessel:

See breakbulk vessel

Veteran car:

A car constructed before 1919, especially one made before 1905 Only the latter are permitted to take part in the London-Brighton Commemoration Run
