Talk:Otto engine

first engine

I just want to know the first engine ever made, thats all. idc if it was designed for transportation purposes or not.--190.23.50.245 (talk) 09:03, 30 September 2015 (UTC)

It would be really nice with more details, and more complete information. For example, it seems like he made his first one in 1876, from looking on the internet. But what did it run on, gas? What distinguishes it, and makes it worth mentioning so many places? That it was the first one to use spark plugs, or maybe it was just the first working engine with pistons? It seems that in some contexts "otto engine" means an engine that uses spark plugs, as opposed to diesel engines, and this term is also used about modern cars.

I do agree that much more information could be added on this topic. Fortunately due to the technology age, all the books about it are public domain in the United States (anything published prior to 1923), and so any book or journal articles and illustrations about it can be directly used in this article. The big challenge is finding those very old citations and articles, though searching Google Books may be helpful. DMahalko (talk) 17:33, 6 January 2009 (UTC)

evaporative cooling

some of the older engines seem to have had evaporative cooling with the cylinder in a open water reservoir.

precursor?

Is this engine in some way a precursor of the modern car engine? If so this should be mentioned in the first paragraph. 84.108.160.70 (talk) 06:28, 17 February 2011 (UTC)

No it is NOT. The engine discussed here, is NOT THE Otto Cycle engine. (The video clip is though) It is the Otto Atmospheric engine which is based on the 1860 work of Jean Joseph Etienne Lenoir. Like the Lenoir engine, these are huge, low rpm, low efficiency engines.

The Lenoir engine ran at 4% efficiency while the Otto Atmospheric engine ran at 12%. The Otto Compressed charge engine was produced in 1876 and is a stratified compressed charge engine (it is important to know this so that you can see why Daimler was able to evade the Otto patent). The Lenoir and Otto Atmospheric engines ran on "Illuminating Gas." Otto's company was later referred to as the Deutz Gasmotorenfabrik company. (based in the town of Deutz and still exists).

These are stationary engines, as was the Otto cycle engine which was first produced in 1876. The Otto Cycle engine ran at 30% efficiency.

This page is incompetent in not properly identifying the engine and in falsely associating this atmospheric engine with the Otto cycle engine. This is FALSE. The original Otto Atmospheric engine can be seen running on illuminating gas on a Youtube video. 69.140.106.140 (talk) 00:02, 17 May 2011 (UTC)

Removed the incorrect references which confused the details of the atmospheric and compression engines. Removed the claim that the otto engine used a spark plug, it used flame induction. Removed other false statements and entered references to support accurate information. —Preceding unsigned comment added by 69.140.106.140 (talk) 13:24, 19 May 2011 (UTC)

"First use in transportation" section poorly sourced, questionable

The article's "First use in transportation" section is apparently very poorly sourced (when sourced at all), and therefore very questionable.

That section appears to simply be a transcript of a self-adulating Daimler promotional video (or its introductory text), rather than a reliable and neutral source.

For a topic of this historic importance and gravity, multiple independent (and preferably authoritative, independent, academic and technical media) sources should be widely available online.
