Talk:Nicolaus Otto

message: Many sources, incl. this one indicate that he was born on June 14 and died on Jnuary 28, so I am correcting the dates.
why would the source dates be wrong? people may have simply changed the date of death to patent some of his discoveries. dicoveries that he may not have made.
::Two sources that are both from the Otto museum have his birth date listed differently.  It's either the 10 or June of the 14th of JuneDigitallymade (talk) 12:12, 8 July 2016 (UTC)
thread_title: Birthdate

message: According to this site, http://ia.essortment.com/nikolausaugust_rcoe.htm, Etienne Lenoir invented the very first internal-combustion engine running on expensive gas. Nicolaus Otto is the first to invent a four-stroke internal combustion engine powered by liquid fuel.
::The gas was illuminating gas and it was manufactured by heating coal and then filtering the gas through water.  It was pioneered by Philippe LeBon in Paris.
::If we go by the strict definitions of what a particular prototype is, Otto wasn't first in anything.  Lenoir had an actual automobile in 1863.  There were others before Lenoir also.  What's most significant is did a particular "invention" lead to progress?  Lenoir's engine is the basis for successful internal combustion engines that ran on petroleum.  Otto's was the first engine to successfully implement compressed charge at which many engineers had failed for decades (including Otto from 1862 until 1876).
::There are a lot of people who are researching this history NOW who are falling victim to the people of that period who we would now refer to as "Patent Trolls."  People like Beau De Rochas who never built anything but based a theory on Sadi Carnot's work. Digitallymade (talk) 11:42, 8 July 2016 (UTC)

thread_title:  First to invent the internal-combustion engine? 

message: A lot of the information in this article (e.g. about Daimler, Maybach and Benz) is about the development of the internal combustion engine rather than about Otto himself.  I think these parts of the article should be moved to Internal combustion engine.  Biscuittin 15:05, 9 October 2007 (UTC)
thread_title:  Allocation of text 

message: He invented the first 4 stroke engine.  Not the first internal combustion.  Needs a rewrite.
: No, he did not. Christian Reithmann (Christian Reithmann) (1860) and Alphonse Beau de Rochas (1862) did. Otto reinvented the four stroke engine.  --Sigmundg (talk) 02:44, 3 February 2012 (UTC)
replies: text: Beau De Rochas wrote a paper based on Carnot's work and received a patent.  He was what we call a "Patent Troll" today just as Selden was in the USA.  Selden finally lost his patent when he was forced to build an engine.  Rochas did not build anything and probably wouldn't have been able to.  He is significant for ONE reason only.  His patent, which never had a physical specimen to illustrate the principle was used to overturn 1 of Otto's 25 or so patents which allowed Gottleib Daimler to escape royalties on his high speed engines.

thread_title: Video 

message: From a British school science TV programme I heard in the 1970s I recall that a model of his internal combustion engine was hidden during the Second World War as, I recall it said, "the Nazis would have wanted to destroy it because Otto was a Jew", but it was hidden and preserved, and was shown on the programme.   The article appears silent on this - is there evidence he was Jewish?Cloptonson (talk) 12:13, 18 October 2014 (UTC)
thread_title:  Otto Jewish? 

message: The modern automobile is not based on any of the three Otto engine types.  While people have often called modern gasoline engines "Otto" engines this is actually an inaccurate and sloppy attribution.  The Otto engine was never capable of more than 200 rpm.  Otto's company abandoned the Otto engine in 1917 and switched entirely to Diesel Engine Production.  Salient points:
# Otto Engines were huge for very low output
# Otto Engines ignition system did not support revolving speeds higher than 200 rpm
# Otto Engines ran on Illuminating gas until long after Daimler created the first liquid petroleum engine
# Otto Engines are PUSH engines using a layering system which causes a continuous push as the piston traveled
# Otto Engines could not be easily throttled
The modern automobile engine is in fact the Daimler Engine
# Daimler's engines ran on Liquid petroleum of the brand name Ligroin, which was a solvent (Hexane-N) and were the first Liquid Petroleum engines
# DMG engines were small
# The first DMG engine revved at 600 and very soon later reached 900 rpm
# Daimler's engine was easily throttleable
# Daimler's engine was an Explosion engine 
Otto's company became the Deutz Company whose Diesel engines are closer to an Otto engine than Daimler's are.
Daimler's company Became Daimler-Benz (now called Mercedes-Benz) and makes the same type of engine Daimler developed in 1883 Digitallymade (talk) 12:03, 8 July 2016 (UTC)
thread_title:  Just for Clarity 

message: It is clear from Otto history that he was aware of ONLY the Lenoir engine.  He first engine built in 1861 was a copy of Lenoir's engine.  All his work after that was his and his alone.  
There were dozens of engineers who created patents and  working prototype engines.  The Otto Engine was the first commercially successful engine.  Rochas never built an engine.  Lenoir built cars in 1862.  Otto's plant manager Gottleib Daimler who had seen the Lenoir engine built it for Otto and was unaware of the work of Carl Benz, which was not too far away from him.  Otto's, Daimler's, and Benz companies all exist today because their inventions were significant and commercially successful.  Simply having an idea that leads no where, deserves no more than a passing mention.  Otto knew of Lenoir's engine only.
This is a common occurrence throughout history.  Gustave Whitehead built the first airplane, but Wright get the credit.  People who created patents for unsuccessful inventions are seldom remembered.  If their patent didn't lead to progress, then it deserves no mention, such as Rochas and Lenoir.
Christian Huygens invented the internal combustion engine in 1678. The Barsanti engine bears no resemblance to the 3nd Otto engine which was a compressed charge engine.  That is the engine referred to as the Otto engine and which was the foundations for Daimler's engine which is the foundation of all modern compressed charge ic engines.Digitallymade (talk) 06:37, 11 July 2016 (UTC)
thread_title:  Earlier Patents? 

message: The only reason we know of the Rochas patent today is that Daimler used it to avoid paying royalties to Otto.  Otto had 25 patents.  The Rochas patent was used to void only 1 of them, in Germany.  Rochas never built and engine.  His patent was merely a reiteration of the world of Sadi Carnot.
Diesel also used the work of Sadi Carnot to build his engine in 1896.
The Otto engine originally looked like this and hardly changed through it's life.  Only the 3rd Otto engine design is considered to be the Otto Engine.
There is no Rochas engine.
Barsanti's engine looks like this:
The Barsanti is a free piston engine like the 1864 Otto engine.  It does not appear to compress the fuel charge or run on four cycles.  I've found nothing in the provided reference to support the assertion about it that was made here.  
This page is massively incorrect in every section.Digitallymade (talk) 07:19, 11 July 2016 (UTC)
thread_title:  The Rochas Patent 

message: Piston engines have only one cycle. A cycle can be a two-stroke cycle or a four-stroke cycle. There's no such thing as a four-cycle engine. It's four-STROKE engine.2604:2000:C682:2D00:AD33:E71D:5E66:7505 (talk) 02:46, 17 March 2018 (UTC)

message: I have seen that the English article on Otto spells his first name Nicolaus with a K rather than a C, which I find odd. Therefore, I have searched through a couple of publications to find out which name variant is correct. I have limited my search to monographs and books that have at least a large section dedicated to Otto, and I have omitted works that only summarise key facts about Otto, but mainly describe a different topic. Most sources spell the name Nicolaus with a C rather than a K:
Only one article that I have found actually spells the name with a K: E. C. S.: Nikolaus August Otto, 1832–1891, in Nature, number 3268, volume 129, 18 June 1932, p. 892.
Most scientific works that aren't describing Otto as a person, but still mention his name, spell it as "Nicolaus", which is especially true for works in Otto's native language, German. Scientific works that use the "Nikolaus" variant seem to be less common. However, needless to say, it is not possible to analyse all publications that mention the person Otto, therefore, this can only be considered a rough estimate. The same is true for other, non-scientific sources. Virtually all (non-scientiic) sources that spell the name as "Nikolaus" seem to be either not well-researched internet pages, or questionable BOD-books.
In addition to that, I have looked through Otto's patent applications. In all of them, he has spelled his name as Nicolaus (Example, in English). Also, in Deutz press releases, the name is spelled with a C. (See Deutz press release "125th anniversary of the death of Nicolaus August Otto" (2016)).
I will therefore move the article to the correct lemma. --Johannes (Talk) (Contribs) (Articles) 12:54, 6 May 2020 (UTC)
