Gas-dynamic trap

The gas-dynamic trap (GDT) is an axially symmetric magnetic mirror device for plasma confinement, first proposed and studied at the Budker Institute of Nuclear Physics in Novosibirsk.

Gas-generator cycle

The gas-generator cycle is an open liquid rocket engine power cycle in which a small fraction of propellant burned in a gas generator drives the turbine pumps, with exhaust dumped overboard.

Gas-insulated line

A gas-insulated line (GIL) is a high-voltage power transmission system in which a conductor inside a compressed insulating gas carries large amounts of power underground or through tunnels.

Gas-operated reloading

Gas-operated reloading, also called the gas-operated action, is a firearm mechanism that uses propellant gas from a fired cartridge to cycle the action and load the next round.

Gas-source molecular beam epitaxy

Gas-source molecular beam epitaxy, also called chemical beam epitaxy or gas source MBE, grows epitaxial semiconductor layers in vacuum from beams of gaseous sources like arsine.

GASBOL Gas Pipeline

The GASBOL gas pipeline (Gasoduto Bolívia-Brasil) is a 3,150-kilometer natural gas pipeline from Rio Grande, Bolivia, to southern Brazil, the longest in South America, operating since 1999.

GASCADE Gastransport

GASCADE Gastransport is a German long-distance gas transmission system operator headquartered in Kassel, running a roughly 3,700-kilometer high-pressure pipeline network and converting growing portions of it to hydrogen.

Gasoducto Norte Gas Pipeline

Gasoducto Norte, the Northern Pipeline, is an Argentine natural gas pipeline built in 1960, running from Campo Durán in Salta toward Buenos Aires.

Gasoline

Gasoline, also known as motor spirit, gasolene, or bensin, is a volatile hydrocarbon fuel refined from crude oil and blended with additives and ethanol, used mainly in vehicle engines.

Gasoline compression ignition

Gasoline compression ignition (GCI) is a low-temperature combustion strategy, first studied by Gautam Kalghatgi, in which gasoline autoignites under compression alone in a diesel-type engine, suppressing soot and NOx.

Gasoline direct injection

Gasoline direct injection, also called petrol direct injection, is a fuel system for spark-ignition engines that injects fuel at high pressure directly into the combustion chamber.

GasPort FSRU

GasPort FSRU is an LNG import terminal at Port Qasim, Pakistan, Pakistan's second, using the floating storage and regasification unit BW Integrity and operating since 2017.
