What is a turbo encabulator?
The turbo encabulator is a fictional machine. It comes from a 1944 engineering parody that describes an impossible device in confident, impressive-sounding jargon that means nothing at all. Engineers have shared the joke ever since, in print, on mock data sheets and in famously straight-faced spoofs of industrial training films.

Origin (1944)
The joke began in Britain during the Second World War. A piece by John Hellins Quick, titled "The turbo-encabulator in industry", appeared in the Students' Quarterly Journal of the Institution of Electrical Engineers in December 1944 (volume 15, issue 58, page 22). IET Digital Library, DOI 10.1049/sqj.1944.0033; Wikipedia, "Turbo encabulator".
It reads like a sober technical report on a new machine. Every sentence has the rhythm of real engineering writing, and almost none of the nouns exist. Much of the vocabulary is invented. One of the coinages, in the passage as Wikipedia quotes it, is the word prefamulated
(Quick, 1944).
Another is marzlevanes
(Quick, 1944), a set of parts that nobody has ever seen, ordered or replaced. The effect is the whole point: a reader who knows the field recognises the tone at once and the content never. Spellings of the invented words differ between reprints and the later films; we follow the passage as Wikipedia quotes it and have not compared it with the 1944 printing.
How it crossed the Atlantic (1946)
The piece reached a much larger audience two years later. According to Wikipedia's account, a New York lawyer named Bernard Salwen, whose work included reviewing technical manuscripts, came across it reprinted in an industrial bulletin published by Arthur D. Little and wrote about it for Time magazine in the issue of 15 April 1946. Wikipedia, citing Time, 15 April 1946.
Readers wrote in. Time's letters pages came back to the story in the issues of 6 May 1946 and 3 June 1946. According to Wikipedia's account, the editors reported that some readers had wanted to be sure the magazine was in on the joke.
The data sheet (1962)
In 1962 engineers at General Electric's Instrument Department in West Lynn, Massachusetts, gave the machine a mock product data sheet, laid out in the same format as the real pages of the company's handbook. Wikipedia, citing the 1962 sheet. A joke that had been an article was now a "product", with the paperwork to prove it.
The films
The version most people meet today is on film. According to accounts of the film gathered by Wikipedia, the actor Bud Haggart, who worked in industrial training films around Detroit, performed the first filmed version in about 1977, directed by Dave Rondot, after a shoot for a GMC Trucks training film. Wikipedia (which marks this account as needing a better source).
Later versions followed: films associated with Rockwell Automation, a "Retro Encabulator" presented by Mike Kraft in front of an Allen-Bradley motor control centre, versions made in the style of Chrysler's "Mastertech" training series, and in 2022 a "HyperEncabulator" from the SANS Institute's industrial control systems team. Wikipedia. The presenter always plays it perfectly straight. We have a short page about the Retro Encabulator video.
Why it endures
The turbo encabulator has lasted because it is a precise parody of something real. Anyone who has read a specification, sat through a product briefing or been handed a slide full of acronyms knows the feeling of language that sounds exact and explains nothing. Writers on engineering and experimental method cite it as an example of obfuscation by excessive jargon. Wikipedia, citing Moffat and Henk, Planning and Executing Credible Experiments (2021).
It is also affectionate. The joke is made by engineers, for engineers, and it only works if you love the real thing enough to hear what is wrong.

Common questions
Is the turbo encabulator a real machine?
No. It is a parody. No such machine has ever been built, and the description was written so that it could not be.
Who wrote the turbo encabulator?
John Hellins Quick. His piece was published in December 1944 in the Students' Quarterly Journal of the British Institution of Electrical Engineers.
What is the Retro Encabulator?
It is one of the later film versions of the joke, presented by Mike Kraft with an Allen-Bradley motor control centre as the prop. Our page on the Retro Encabulator explains where it fits.
Is it "encabulator" or "encabultor"?
The famous joke is spelled "encabulator". This site is called Turbo Encabultor on purpose: we machined one "a" out of the name to save weight. People also search for "turbo incabulator" and "turbo encabulater"; they all mean the same joke.
Is this site connected to any of the companies in the films?
No. Turbo Encabultor is an independent parody and novelty site made by WeldonPC. It is not affiliated with or endorsed by any company, magazine, institution or person mentioned on this page.
