Gas Bypass Line

A term used for hot-gas bypass line.

Gas Bypass Valve

A term used for hot-gas bypass valve.

Gas Cylinder

A container used for the transportation and storage of compressed gas.

Gas Defrosting

The use of hot, high-pressure gas in the evaporator to remove frost or ice buildup.

Gas Fade

Brake fade due to hot gases and dust that reduce friction between the drum or rotor during prolonged hard braking.

Gas Guzzler

A vehicle having excessive fuel consumption.

Gas Hog

A term often used for gas guzzler.

Gas Lift

See gas strut.

Gas Ports

A series of holes drilled from the crown of a piston to the top ring groove, providing combustion pressure to force the ring against the cylinder wall, ensuring a more effective seal.

Gas Prop

See gas strut.

Gas Regulator

A device used to control the delivery of gas at a substantially constant pressure.

Gas Shock

A term used for gas-filled shock absorber.

Gas Strut

A tubular product similar to a shock absorber. One or more typically are used to assist in opening something relatively heavy, such as the lid on a tool box or a tonneau cover. The strut also will hold the lid in the open position, so you have both hands free.

Gas-Filled Shock Absorber

A shock that uses nitrogen gas, at 25 times atmospheric pressure, to pressurize the fluid in the shock to reduce or prevent aeration or foaming. Also known as gas shock.

Gas-Metal Arc Welding (GMAW)

An arc-welding process that uses an arc between a continuous-filler metal electrode and the weld pool.

Gas-Transfer Velocity

The speed at which the air-fuel mixture spreads out in the combustion chamber during the power phase.

Gas-Tungsten Arc Cutting (GTAC)

An arc-cutting process that uses a single tungsten electrode with gas shielding.

Gas-Tungsten Arc Welding (GTAW)

An arc-welding process that uses an arc between a non-consumable tungsten electrode and the weld pool.

Gas-Turbine Engine

An internal-combustion engine in which the shaft is spun by combustion gases flowing against curved turbine blades located around the shaft.

Gasifier Section

The part of a gas-turbine engine that draws in air, mixes it with fuel, and burns the mixture.
