An engine is a mechanical device that produces some form of output from a given input. An engine whose purpose is to produce kinetic energy output from a fuel source is called a prime mover; alternatively, a motor is a device which produces kinetic energy from other forms of energy (such as electricity, a flow of hydraulic fluid or compressed air). A motor car (automobile) has a starter motor and motors to drive pumps (fuel, power steering, etc) – but the power plant that propels the car is called an engine. The term 'motor' was originally used to distinguish the new internal combustion engine -powered vehicles from earlier vehicles powered by a steam engine (as in steam roller and motor roller). Military engines included siege engines, large catapults, trebuchets and battering rams. From Wikipedia under the

Could someone please give me step by step instructions to turn the engines of the Level D 767-300 on? Asked by ZUS - Mon Feb 12 15:28:19 2007 - - 7 Answers - 1 Comments A. You would need the manual for that. From what I know, most of these jets are started with a start switch on the overhead panel and placing the fuel switch to run when the engine reaches 20 percent. Of course, the exact procedures are outlined in the Flight Manual which I don't have access to. Answered by pampapilot99 - Tue Feb 13 22:24:20 2007 Whatever happened to sleeve valve engines? Q. The Hawker Tempest was the fastest piston powered airplane ever made, it had a sleeve valve engine. It was made obsolete, by the Me 262 and other jet engined fighters, But it's engine was the ultimate piston aircraft engine. Then piston engines became something for inexpensive planes, but why has the sleeve valve not undergone further development as a sports car engine? Asked by Cowboy C - Mon Oct 1 22:31:23 2007 - - 4 Answers - 0 Comments A. The main problem was the oil consumption, since a very tight seal required close tolerances that in turn called for very precise lubrication. As Wikipedia states (see link) if one wants to do away with poppet valves, and is willing to accept a very wide lubricated area, one might as well go all the way and go with a Wankel rotary engine which entirely eliminates the need for valve and thus timing gearing. Note that military engines do not have to be certified the way civilian aero engine need be, this in turn makes the process of introducing any change in an engine design extraordinarily expensive, hence general aviation piston engines are rather crude (but proven) design. For automotive engines, one of the concern is the economy of scale:… [cont.] Answered by Vincent G - Tue Oct 2 15:01:32 2007 Jet engines. Is there a specific jet engine that is starting to be build now or in the near future?
Q. Im looking so see how the airline industry is doing. Are their any more jet engines going to be designed, or built soon, or just have gone into production? Specifically with Pratt Whittany. If so do you know the names of the engines? Asked by vnewhalljr - Tue Jun 16 21:20:48 2009 - - 5 Answers - 0 Comments A. Pratt & Whitney is developing the PW1000G which I think is the newest jet engine for that company. Answered by edmundac - Tue Jun 16 22:10:13 2009 From Yahoo Answer Search: "Engines"
