Gasket

1. A metal ring used on some spark plugs to seal pressure between the plug shell and the cylinder head. 2. A piece of thin compressible material such as cork, rubber, or soft metal, placed between two mating surfaces to form a seal.

Gasket

A component that enhances sealing between two parts. Gaskets are made of a wide variety of materials, including cork, copper and silicone. High-performance gaskets typically provide better sealing than stock parts, which is especially important when an engine has been modified to produce more power or have a higher compression ratio. Some performance gaskets can be reused, too. See exhaust gasket, head gasket.

Gasket Cement

A liquid gel or paste adhesive material used to bond gaskets to their mating surfaces.

Gasket Shellac

A liquid form of gasket cement.

Gasohol

In the United States the term gasohol refers to gasoline which contains 10 percent ethanol. This term was used in the late 1970's and early 1980's but has been replaced by terms such as Super Unleaded Plus Ethanol or Unleaded Plus.

Gasoline

A liquid blend of hydrocarbons used as automotive fuel and processed from crude oil.

Gasoline Alley

The infield-garage area at the Indianapolis speedway.

Gasoline Consumption

A term used for fuel consumption.

Gasoline Container

Specially approved OSHA containers used to safely hold and store gasoline.

Gassing

The conversion of battery water into hydrogen and oxygen gas.

Gate

1. A digital circuit with several inputs and one output that performs a logical function such as AND, OR, NOT, NAND, or NOR. 2.The money that is collected for admission. 3. The starting position for a drag race. 4. To take the lead in a drag race right from the start.

Gauge

1. An instrument used for measuring, such as for compression. 2. A dashboard-mounted component used for visual indication of engine and system conditions, such as oil pressure.

Gauge

A mechanical or electrical device designed to inform a driver of what is going on inside a vehicle. Common gauges track the amount of gas in a gas tank, vehicle speed (speedometer), engine speed (tachometer), water temperature and oil pressure. Some vehicles also are fitted with a boost gauge (if it has a supercharger or a turbocharger), a fuel pressure gauge, a voltmeter to track whether the battery is being charged and a transmission temperature gauge. It is possible to add gauges to a vehicle. Gauges can be mounted in or under the dash, on a console or in a gauge pod on the pillar just in front of the driver. Some enthusiasts also mount a tachometer on the steering column. These specialty gauges come in a variety of designs, ranging from Art Deco style faces to racing-style gauges, including some gauges that glow in the dark and others with carbon fiber faces. It's also possible to modify a vehicle's existing gauges with a gauge-face kit to change the look of its interior.

Gauge Pod

gauge cluster that can be mounted on a vehicle's A-pillar, on a console or on a dash.

Gauge Pressure

A pressure indicated on a scale with atmospheric pressure as 0 psi or kPa.

Gauge Set

1. Two or more instruments attached to a manifold and used for measuring or testing pressure. 2. Two or more instruments used to indicate engine and system conditions, such as oil pressure, coolant temperature, and charging-system indicators.

Gauge-face Kit

A restyling kit that changes the color of a vehicle's gauge faces. Common kits will change black-face gauges to white or even yellow.

Gauging Point

The starting point for measuring a part.

Gauss's Law

Karl Friedrich Gauss (1777 - 1855) A German mathematician knowen for his work in magnetism. Gauss's Law stats that the total of the electric flux out of a closed surface is equal to the charge enclosed devided by the permittivity.

GAWR

An acronym for gross-axle weight rating. The maximum allowable weight each axle is designed to carry, as measured at the tires, therefore including the weight of the axle assemble itself. GAWR is established by considering the rate of each of its components (tires, wheels, springs, axle) and rating the axle on its weakest link. The GAWR assumes that the load is equal on each side. see also WEIGHTS.
