- VECI
- Acronym for Vehicle Emission Control Information which is on a decal or label 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 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.
- Vee thread
- Any screw thread having a triangular profile. In 1958, the triangular profile of the Unified screw threads was adopted as the basis of a new international system of screw threads, now known as ISO screw threads. The ISO system of screw threads comprises several metric series (which supersede the S. I. screw threads) and also several inch series (which supersede both the screw threads of Whitworth form and the Unified screw threads).

- Vehicle Emission Control Information
- (VECI) a label in the engine compartment, e.g., pasted to the radiator fan cover, providing information about the engine and emission controls
- Vehicle fuel consumption
- Vehicle fuel consumption is computed as the vehicle miles traveled divided by the fuel efficiency reported in miles per gallon (MPG). Vehicle fuel consumption is derived from the actual vehicle mileage collected and the assigned MPGs obtained from EPA certification files adjusted for on-road driving. The quantity of fuel used by vehicles.
- Vehicle fuel expenditures
- The cost, including taxes, of the gasoline, gasohol, or diesel fuel added to the vehicle's tank. Expenditures do not include the cost of oil or other items that may have been purchased at the same time as the vehicle fuel.
- Vehicle Identification Number
- (VIN) Number assigned to a vehicle by the manufacturer primarily for registration and identification purposes (consisting of numerals and letters).
- Vehicle importer
- An original vehicle manufacturer (of foreign or domestic ownership) that imports vehicles as finished products into the United States.
- Vehicle Maintenance Reporting Standards
- (VMRS) A set of codes developed to facilitate computerized tracking of parts and labor used in equipment repair. Established and maintained by the American Trucking Associations.
- Vehicle miles traveled
- (VMT)
- The number of miles traveled nationally by vehicles for a period of 1 year. VMT is either calculated using two odometer readings or, for vehicles with less than two odometer readings, imputed using a regression estimate.
- A unit to measure vehicle travel made by a private vehicle, such as an automobile, van, pickup truck, or motorcycle. Each mile traveled is counted as one vehicle mile regardless of the number of persons in the vehicle.
- Vehicle speed sensor
- (VSS) sensor in speedometer cluster which sends the vehicle speed information (i.e., how fast the car is traveling) to the electronic control module
- 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 majority of cars produced in North America.
V-eight engine
- Velocity
-
- The rate of motion in a particular direction.
- Quickness or rapidity of motion, swiftness, speed.
- 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
- 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
- Vent
-
- 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 louvers) 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).
- A small triangular window for letting air into the passenger compartment.
- A passageway or conduit for conveying products of combustion from fuel utilization equipment, or their vent connectors, to the outside atmosphere.
- 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.
- Vent connector
- That portion of the venting system that connects the flue outlet of fuel utilization equipment to the gas vent or single-wall metal pipe.
- Vent gases
- Products of combustion from fuel utilization equipment plus excess air, plus dilution air in the venting system above the Draft regulator or similar device.
- 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
- Ventilation
-
- A provision of a free or controlled circulation of air.
- Forced airflow, by design, between one area and another.
- The natural or mechanical process of supplying conditioned or unconditioned air to, or removing such air from any space.
- Ventilation air
- That portion of supply air which comes from the outside (outdoors) plus any recirculated air that has been treated to maintain the desired quality of air within a designated space.
- Ventilation slot
- A series of gaps in the wheel disc which allow the passage of air to assist brake cooling
- 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.
- Vent limiter
- A means that limits the flow of air from the atmospheric diaphragm chamber of a gas pressure regulator to the atmosphere. This may be either a limiting orifice or a limiting device.

- 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.
- 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.
- 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
