Broekn links: Some links are incorrect. Mainly this http://www.epa.gov/lmop/res/handbook.htm I believe the correct link is this http://www.epa.gov/lmop/publications-tools/handbook.html I ask someone to fix them please as I do not know how. — Preceding unsigned comment added by 77.125.105.116 (talk) 18:06, 1 November 2013 (UTC)

ICE's and gas turbines
The article was talking about "internal combustion engines" as opposed to "gas turbine engines". Gas turbines ARE internal combustion engines. If the fuel is burned inside the engine, it's an ICE. Even a rocket is technically an ICE. A steam turbine or engine is an external combustion engine, since the fuel is burned outside the engine to heat the steam; the energy is then extracted from the steam inside the engine. One works by heating water outside the engine (usually), the other works by heating air inside the engine. A gas turbine meets this description fully. Also I'm not sure I understand why the gas must be compressed more to use in a turbine than in a piston engine. The only pressurization more normal fuel requires in either case is what comes from the fuel pump, which is powered by the engine at a small loss in efficiency (although typically gas, such as LPG is pressurized, it's only for storage purposes). A diesel engine requires higher pressures to inject into the high pressure of the cylinder, but that's made up for by the greater efficiency. I don't see any reason why the same shouldn't apply to a gas turbine engine. I don't see why either should fundamentally require the gas to be pressurized, although it would probably make storage and transport easier to do so. AnnaGoFast (talk) 19:50, 15 May 2016 (UTC)
