your page: http://www.newworldencyclopedia.org/entry/Internal_combustion_engine contains inaccuracies.
There is nothing intermittent about the combustion of an Wankel engine.
There is no greater pollution created than that of nuclear plants, the production of batteries for hybrid cars, or the combustion products of two-cycle IC engines and air cooled IC engines. The modern four cycle which is not a hybrid is the most ecologically “friendly” automobile product.
Automobiles are NOT wasted as you suggest once they wear out. The various components are among the most highly recycled.
The 1860 Lenoir engine has no resemblance to a walking beam engine. It resembled the steam cylinder of a locomotive.
You have left out the 1861 Otto Compression engine attempt that failed.
Your date on the Otto Atmospheric engine is wrong, it was 1864, not 1862.
Lenoir built an unsuccessful car in 1862. It ran but was still unsuccessful.
the Marcus engine was not successful and broke immediately and was never tried again.
Otto’s had 1 of 25 patents voided in 1886, not as you suggest in 1876. The basis for doing this was also false. The court did not understand the Otto layered charge principle. The jealous German industrialists who wanted to make Otto engines had conducted a patent search and found an obscure patent for an engine that was never built (indeed Rochas could not have built it). Besides, Otto had attempted that same engine design in 1861 and failed. The overturning of the single German patent simply allowed the German companies to make the engine from 1886 instead of having to wait until 1891, when it would have expired in any event. The Rochas patent was of no importance. If you have to mention it, you should give the correct year.
The 1900 Maybach automobile from Daimler-Benz was name in honor of Jellinek’s daughter as the Mercedes-Benz, not as you claim the Daimler-Mercedes.
As for applications, IC engines were created as stationary power applications and continue to be used world wide in industry for that purpose. This is far more common than you imply. There are many power plants that use IC engines for electrical generation. Increasingly the IC engine is part of Combined Heat and Power Solution as well.
Under Operation your description of which fuels can be used in IC engines is inaccurate. You do not mention that it is only the Diesel engine that can run biofuels all the way up to light refractions as well. The Otto engines are limited to the lightest of the refractions, and do not run without significant modification fuels other than gasoline.
Gasoline ignition has seldom required the presence of a battery to provide the electricity for a spark. In 1884 Otto (Deutz) created the magneto, which was superior to the battery technology of that era. Today the VAST majority of engines in use are magneto ignition. The old battery and coil has been replaced by capacitor discharge ignition systems in automobiles and sophisticated engines. Small engines, industrial engines, motorcycles, chain saws, ag equipment, and other types are still magneto designs.
Modern Diesel injection systems inject fuel at five different times and sustain the push against the piston for some time, unlike an Otto engine which has a single big push. They are also electrically controlled by computer so the electrical system are NOT secondary. Only older diesels which used electricity for starting only meet your antiquated description.
Energy.. your statement is false. The energy in the fuel air mixture is the same both before and after combustion. Energy cannot be either created or destroyed, only moved around. What changes is the pressure in the cylinder as a result of the working gas temperature rising. That converts the chemical energy to kinetic energy.
The exhaust gases are still very hot and in some engines are processes again in a variety of ways to gain back some of the lost energy. This is found mostly in industrial applications and prototypes as it is expensive.
Engine naming is not uniform. All automobile engines, are engines. But an outboard engine is always an outboard motor.
The term stroke, while still used, was deemed inaccurate decades ago. Engines are described by their cycle types, which include a great deal more detail information than merely talking about stroke.
Jet and Rocket engines do NOT confine the fuel air mix and are NOT internal combustion engines. They are reaction engines.
end of this part.
