engine - disambiguation

morris da moose says this page sucks cause me spent like an hour searching for a pic of a car engine and not 1 found

Can someone explain the difference between a motor and an engine in the article? basilwhite 18:45 EST Feb 11, 2006

this should be a disambiguation page. strictly, an engine is a device that converts heat into work. new uses of the word are obviously quite different

Yes, please add a disambiguation page. Was just looking for a link for "engine" in the "video game engine"/software sense.

The Difference Between an Engine and a Motor

I have also been puzzled by the difference between an "engine" and a "motor." I think this is a question that is best answered by someone who has the credentials to do so, but I would like to provide two references and state my opinion on the subject.

Frederick J. Carranti, P.E. of Syracuse University posted a message defining the two terms. He defines a motor as a "device which converts electrical energy into mechanical energy." Then he goes on to define engine as a "device that converts chemical energy or heat energy into mechanical energy."

The Wikipedia Article on Internal combustion engines states that "although the terms sometimes cause confusion, there is no real difference between an 'engine' and a 'motor.'" That statement is not referenced, so personally I do not find that to be a credible source for information.

I have yet to find any source that defines the two terms opposite of the first source that I referenced, therefore I think the controversy is only whether or not there is a difference.

I think the first source defined the difference well and should be taken into account in the related Wikipedia articles on the subject. I would, however, like there to be a more stable reference that can be cited rather than just a forum post. SpikeBoy 06:06, 17 February 2007 (UTC)[reply]

Loose definition

"An engine is something that produces some effect from a given input." Sorry, "some effect"? Mechanical/Kinetic energy may fit better?

'modern' engines

This section is extremely skewed. After a huge time jump from the previous section, it briefly hints that other types of engine have existed and then goes on to the history of the internal combustion engine - which ought to be covered by internal combustion engine.

General

This should be the top-level article linking into the various types of steam engine, various types of ICE, and other engines, which surely include windmills, watermills, HEP turbines, etc, etc EdJogg 00:46, 1 March 2007 (UTC)[reply]

Agree totally. And with removal of most of ICE stuff. Intro is horrible, Usage and Antiquity sections are on the right path. Someone get editing ! Jimbowley (talk) 18:58, 29 November 2007 (UTC)[reply]

Aircraft Engine

"Again an aircraft will have many motors installed for operation of its many auxiliary operations and services, but aircraft are propelled by engines, in this case, jet engines." This is not strictly accurate. Not all aircraft have multiple motors, not all even have an engine(s), as in the case of gliders and balloons. Also, not all aircraft that use an engine(s) use jet engines, as in the case of prop planes. If there is no objection in the next month or so I will remove the sentence. 67.160.147.2 (talk) 01:43, 18 February 2008 (UTC)[reply]
