|This is the talk page for discussing improvements to the Throttle article.
This is not a forum for general discussion of the article's subject.
|This article is of interest to the following WikiProjects:|
Some form of this article needs to exist to link together throttle body, carburetor, and gas pedal/accelerator. This article overlaps significantly with those articles, and this article is a tad schizophrenic, but I still think this page is still useful, as many articles want to link to the general idea of a throttle, without specifying fuel-injected or non-fuel-injected throttles. Also, the gas pedal bit doesn't really have a home, and I think that information should be located here while it's still a stub. Also, it may be generally interesting to compare/contrast how different engines do power regulation. --Interiot 16:29, 16 April 2006 (UTC)
I have cut the following text...
Main article: Afterburner
- Some military aircraft have a feature known as afterburner. This gives the aircraft far more speed. On these aircraft the throttle has an indent in order to push it into afterburner. Some aircraft have another indent ahead of this which is used for combat situations, however this is rarely used as it damages the engine and airframe. ...because this has nothing to do with the subject of the article. "Throttle" is used here to refer to the power control lever used by the pilot. Paul Beardsell 19:41, 26 February 2007 (UTC)
Should NOT just cut Afterburners, but IMPROVE on the description
People should understand that an ovelzealous, censorship attitude does NOT improve Wikipedia! In this case, the description is about some special Throttle Settings used in aviation engines. Instead of amputating this point, let's re-arrange it and correct some concepts, in order to cover the subject more completely. (Even the "rate the page" pop-up section includes the concept of "completeness" and has the possibility of rating the page with top completeness with the 5-star option named "Comprehensive coverage". With this kind of removals, it would never reach that status!
I propose to rewrite the paragraph as follows, in order to relate more to the "throttle" and less to "afterburners", but including the related concept:
The throttle control in aviation engines can have some special settings in order to meet certain operational conditions; In military aircraft powered by piston engines it was a common practice to provide a kind of limiting stop or detent, that limited the maximum power to a certain fraction of absolute maximum power that the engine could deliver in continuous conditions, and in case of a war emergency, that detent or mechanical stop could be overridden to extract the absolute maximum power of the engine; but only for a limited span of time and/or requiring the pilot to closely observe its instruments to monitor temperature rising too much and risking a sudden engine failure. This was appropriately called "W.E.P." or "war emergency power" setting, and also served the purpose of telling the maintenance mechanics that the maximum continuous power had been exceeded sometime during that mission. On military (and at least one civilian -Concorde-) aircraft jet engines, the throttle can include an special setting that activates the afterburners, which increase maximum thrust far above that of the turbine without afterburner, mainly used during take off and in combat situations. In civilian passenger and transport jets, there is another setting at the lower end of the range just above minimum idle called "Flight Idle" used when there is the need to reduce the aerodynamic drag that the engine contributes in order to maximize the glide or reduce the fuel consumption to the absolute minimum without shutting down the engine.
Well, it IS related to throttle now, and could be included again. Amclaussen.
Diesels do now have throttles
See http://delphi.com/manufacturers/cv/powertrain/mvrv/, I've not edited wikipedia before, so perhaps someone would like to show the light? It seems they are used to enhance EGR. —Preceding unsigned comment added by 126.96.36.199 (talk) 07:12, 8 September 2008 (UTC)
- I have added this to the Diesel bit. Hope this makes sense.--Turtle (talk) 22:00, 5 November 2008 (UTC)
firewall the throttle
ANSWER: this term means the same as the familiar expression that says: "Pedal-to-the-Metal!" and both mean opening the throttle to the maximum, since it is usual to have the accelerator pedal or "gas pedal" mounted to the metallic wall called "Firewall" that divides the engine compartment from the passenger or driver compartment. Another one is "Flooring the Throttle" which means "firewalling it". Amclaussen.
removed Computing section
I removed the Computing section about computer CPU throttling (speed control). At first I moved it to another article but then discovered dynamic frequency scaling already covers the topic, and much better than what was here. So I added that to throttle (disambiguation) to catch the other uses link from this article. Ikluft (talk) 07:12, 10 February 2009 (UTC)
Should someone add this section? Even though its a bad invention eg it drains battery life from your scooter if its an ev, it should be added because its universal. I'm actually against it and for button pressurized accelerators which havent been invented yet and here's why:
Magnets are dangerous, Ill tell you why. They act as decharging devices in scooters. If your electric scooter were a button pressure sensitive spark, it would regenerate the battery. Attach it to an att with a recharging bat and you get infinite energy. Small vehicles can have infinite energy just like the large ones do. Its all a matter of science, i prooved it cus i built one myself. However they are most likely out-done in the industry with powerful motors and low amps. The cars can do it via low amperage on highend devices using secondary motors and wat not, so can mopeds AND motorcycles using button pressurized accelerators which act as a spark plug to the charger port of a controller and att freq attached to a bat. Very small and secret devices will change the industry around. — Preceding unsigned comment added by 188.8.131.52 (talk) 03:00, 8 January 2014 (UTC)
Choke on this
Couple of years ago I went to see a display of vintage cars. Kicking myself now that I never had a camera, because in one of the old cars I noticed the word "Throttle" printed on the hand-operated choke button which, well, choked off the air supply to the carbie. Seems to me Throttle is a misnomer. —Preceding unsigned comment added by 184.108.40.206 (talk) 22:37, 31 January 2010 (UTC)
- YES; is is a mismoner! The proper name would be "Accelerator control" or accelerator pedal... But because the engine speed control usually throttles the engine air intake, it was called that way, while "choke" aptly describes the manual mixture enrichment control, common on old cars before the 1960's, when a bimetallic spiral substituted the manual control. Amclaussen.
- Not necessarily. On (now old-fashioned) carburetors, the choke and throttle were essentially similar mechanical devices, a "butterfly valve", or plate hinged in the center. The only difference was their location: the choke, on the end before the fuel injection, thus controlling the fuel-to-air ratio; and the throttle on the other end, after the fuel/air mixing, thus controlling the total volume of fuel mixture entering the cyllinders, and thus the engine power (and thus the speed.) It probably took a while for the terminology to evolve. Just because it's different from the original doesn't mean it's "wrong". It should be simply chalked up to the ambiguity of the English language.
- And BTW, on the subject of "wrong" usage, there's a school of thought that says the term "fuel" is only properly applied to the mixture of vaporized gasoline, diesel, "petrol", etc., with air, not to the liquid that goes into the tank before it enters the carburetor (or fuel injector).
