1Gas turbine — Microturbine redirects here. For turbines in electricity, see Small wind turbine. For turbines driven by the flow of gas, see Turbine. A typical axial flow gas turbine turbojet, the J85, sectioned for display. Flow is left to right, multistage… …
2gas-turbine engine — Introduction any internal combustion engine employing a gas as the working fluid used to turn a turbine. The term also is conventionally used to describe a complete internal combustion engine consisting of at least a compressor, a… …
3Gas compressor — A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are… …
4Gas meter — A gas meter is used to measure the volume of fuel gases such as natural gas and propane. Gas meters are used at residential, commercial, and industrial buildings that consumes fuel gas supplied by a gas utility. Gases are more difficult to… …
5Gas turbine locomotive — A Gas turbine locomotive is a locomotive powered by a gas turbine. The majority of gas turbine locomotives have had electric transmission but mechanical transmission has also been used, particularly in the early days. The advantage of using gas… …
6Gas turbine-electric locomotive — DescriptionIn a GTEL a turbine engine, similar to a turboshaft engine, drives an output shaft that is in turn attached to an electrical generator via a system of gears. This in turn powers the traction motors. In overall terms the system is very… …

8Exhaust gas recirculation — (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in most gasoline and diesel engines.EGR works by recirculating a portion of an engine s exhaust gas back to the engine cylinders. Intermixing the incoming air with recirculated… …
9Compression ratio — For compression ratio in data compression, see data compression ratio. The compression ratio of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its… …
