History of the internal combustion engine

Various scientists and engineers contributed to the development of internal combustion engines. In 1791, the English inventor John Barber patented a gas turbine. In 1794 Thomas Mead patented a gas engine. Also in 1794 Robert Street patented an internal-combustion engine, which was also the first to use liquid fuel (petroleum) and built an engine around that time. In 1798, John Stevens designed the first American internal combustion engine. In 1807, French engineers Nicéphore (who went on to invent photography) and Claude Niépce ran a prototype internal combustion engine, using controlled dust explosions, the Pyréolophore. This engine powered a boat on the Saône river, France. The same year, the Swiss engineer François Isaac de Rivaz built and patented a hydrogen and oxygen powered internal-combustion engine. The fuel was stored in a balloon and the spark was electrically ignited by a hand-operated trigger. Fitted to a crude four-wheeled wagon, François Isaac de Rivaz first drove it 100 meters in 1813, thus making history as the first car-like vehicle known to have been powered by an internal-combustion engine. In 1823, Samuel Brown patented the first internal combustion engine to be applied industrially in the U.S.; one of his engines pumped water on the Croydon Canal from 1830 to 1836. He also demonstrated a boat using his engine on the Thames in 1827, and an engine-driven carriage in 1828. Father Eugenio Barsanti, an Italian engineer, together with Felice Matteucci of Florence invented the first real internal combustion engine in 1853. Their patent request was granted in London on June 12, 1854, and published in London's Morning Journal under the title "Specification of Eugene Barsanti and Felix Matteucci, Obtaining Motive Power by the Explosion of Gasses". In 1860, Belgian Jean Joseph Etienne Lenoir produced a gas-fired internal combustion engine. In 1864, Nicolaus Otto patented the first atmospheric gas engine. In 1872, American George Brayton invented the first commercial liquid-fueled internal combustion engine. In 1876, Nicolaus Otto, working with Gottlieb Daimler and Wilhelm Maybach, patented the compressed charge, four-stroke cycle engine. In 1879, Karl Benz patented a reliable two-stroke gas engine. In 1892, Rudolf Diesel developed the first compressed charge, compression ignition engine. In 1926, Robert Goddard launched the first liquid-fueled rocket. In 1939, the Heinkel He 178 became the world's first jet aircraft. In 1954 German engineer Felix Wankel patented a "pistonless" engine using an eccentric rotary design.

*1853–1857: Eugenio Barsanti and Felice Matteucci invented and patented the Barsanti-Matteucci engine, an internal combustion engine using the free-piston principle in an atmospheric two cycle engine. Their 1857 British patent no. 1625 describes the principles of the free piston engine where the vacuum after the explosion allows atmospheric pressure to deliver the power stroke.
*1856: in Florence at ''Fonderia del Pignone'' (now Nuovo Pignone, later a subsidiary of General Electric), Pietro Benini realized a working prototype of the Italian engine supplying 5  HP. In subsequent years he developed more powerful engines—with one or two pistons—which served as steady power sources, replacing steam engines.

1860–1920

*1860: Jean Joseph Etienne Lenoir invented a gas-fired internal combustion engine, and applied for a patent titled ''Moteur à air dilaté par combustion des gaz''. His engine is similar in appearance to a horizontal double-acting steam engine, with cylinders, pistons, connecting rods, and flywheel in which the gas essentially took the place of the steam. Allegedly, several of these engines were built and used commercially in Paris. Friedrich Sass considers the Lenoir engine to be the first functional internal combustion engine.
*1861: Nicolaus Otto ordered Michael Joseph Zons to build a copy of the Lenoir engine for experimental purposes. Later that year, Zons built a second engine for Otto, a four-cylinder, two-stroke unit.
*1861: Alphonse Beau de Rochas invented the four-stroke operating principle. He published an essay titled ''Nouvelles recherches sur les conditions pratiques de l'utilisation de la chaleur et en général de la force motrice. Avec application au chemin de fer et à la navigation'', and applied for a patent. The patent was granted in France, however, it consists of text only, but does not include any drawings of a four-stroke engine. The patent was eventually declared invalid after two years; no copy has been kept in the French patent office's archive.
*1863: Otto designed an atmospheric gas engine that was once again built by Zons. Otto tried filing a patent application, but the patent was not granted in Prussia.
*1864: In Vienna, Siegfried Marcus put an atmospheric petrol engine on a handcart. Allegedly, it drove 200 metres.
*1864: Eugen Langen joined Otto, and improved the atmospheric gas engine.
*1865: Pierre Hugon started production of the Hugon engine, similar to the Lenoir engine, but with better economy and more reliable flame ignition.
*1867: Otto and Langen exhibited their free piston engine at the Paris Exhibition in 1867, and they won the greatest award. It had less than half the gas consumption of the Lenoir or Hugon engines.
*1868: Eugen Langen and Nicolaus Otto obtained a patent on the atmospheric gas engine.
*1872: In America, George Brayton applied for a patent on ''Brayton's Ready Motor''. It used constant pressure combustion and was the first commercial liquid fuelled internal combustion engine. In 1876 it was put into production.
*1875: Nicolaus Otto, working with Franz Rings, designed the first functional compressed charge four-stroke engine. In early 1876 it was tested. The engine was a single-cylinder unit which displaced 6.1 dm³, and which was rated 3 PS (2,206 W) at 180/min, with a fuel consumption of 0.95 m³/PSh (1.29 m³/kWh). In 1876, Wilhelm Maybach improved the engine by changing the connecting rod and piston design from trunk to crosshead, (now giving the engine a 400 mm stroke, increasing the displacement to 8.143 dm³), so it could be put into series production.
*1876: Otto applied for a patent on a stratified charge engine that would use the four-stroke principle. The patent was granted in 1876 in Elsass-Lothringen, and transformed into a German Realm Patent in 1877 (DRP 532, 4 August 1877).
*1878: Dugald Clerk designed the first two-stroke engine with in-cylinder compression. He patented it in England in 1881.
*1879: Karl Benz, working independently, was granted a patent for his reliable two-stroke internal combustion gas engine.
*1882: James Atkinson invented the Atkinson cycle engine. Atkinson's engine had one power phase per revolution together with different intake and expansion volumes, potentially making it more efficient than the Otto cycle, but certainly avoiding Otto's patent.
*1884: British engineer Edward Butler constructed the first petrol (gasoline) internal combustion engine. Butler invented the spark plug, ignition magneto, coil ignition, and spray jet carburetor, and was the first to use the word petrol.
*1885: German engineer Gottlieb Daimler received a German patent for a supercharger

*1893 February 23: Rudolf Diesel received a patent for his compression ignition (diesel) engine.
*1896: Karl Benz invented the boxer engine, also known as the horizontally opposed engine or the flat engine, in which the corresponding pistons reach top dead center at the same time, thus balancing each other in momentum.

* 1905: Alfred Buchi patents the turbocharger and starts producing the first examples.
* 1903–1906: The team of Armengaud and Lemale in France builds a complete gas turbine engine. It uses three separate compressors driven by a single turbine. Limits on the turbine temperatures allow for only a 3:1 compression ratio, and the turbine is not based on a Parsons-like "fan", but a Pelton wheel-like arrangement. The engine is so inefficient at about 3% thermal efficiency, that the work is abandoned.
*1908: New Zealand inventor Ernest Godward started a motorcycle business in Invercargill and fitted the imported bikes with his own invention–a petrol economiser. His economisers worked as well in cars as they did in motorcycles.
* 1908: Hans Holzwarth starts work on extensive research on an "explosive cycle" gas turbine, based on the Otto cycle. This design burns fuel at a constant volume and is somewhat more efficient. By 1927 when the work ended, he has reached about 13% thermal efficiency.
* 1908: The Seguin brothers (Augustin, Laurent, and Louis) design the first rotary engine purposely designed for aircraft propulsion - the French Gnome Omega seven-cylinder, which is prototyped in 1908 and goes into production.

* 1916: Auguste Rateau suggests using exhaust-powered compressors to improve high-altitude performance, the first example of the turbocharger.

1920–1980

* 1920: William Joseph Stern reports to the Royal Air Force that the turbine engine has no future in aircraft. He bases his argument on the extremely low efficiency of existing compressor designs. Due to Stern's eminence, his paper proves so convincing there is little official interest in gas-turbine engines anywhere, although this does not last long.
* 1921: Maxime Guillaume patents the axial-flow gas-turbine engine. It uses multiple stages in both the compressor and turbine, combined with a single very large combustion chamber.
* 1923: Edgar Buckingham at the United States National Bureau of Standards publishes a report on jets, coming to the same conclusion as W.J. Stern - that the turbine engine is not efficient enough. In particular he notes that a jet would use five times as much fuel as a piston engine.
* 1925: The Hesselman engine, introduced by Swedish engineer Jonas Hesselman, represents the first use of direct gasoline injection on a spark-ignition engine.
* 1925: Wilhelm Pape patents a constant-volume engine design.
* 1926: Alan Arnold Griffith publishes his groundbreaking paper ''Aerodynamic Theory of Turbine Design'', changing the low confidence in jet engines. Griffith demonstrates that existing compressors are "flying stalled", and that major improvements can be made by redesigning the blades from a flat profile into an airfoil; he goes on to mathematically demonstrate that a practical engine is definitely possible and to show how to build a turboprop.
* 1926: Robert Goddard launches the first liquid-fueled rocket.
* 1927: Aurel Stodola publishes his "Steam and Gas Turbines"—basic reference for jet-propulsion engineers in the US.
* 1927: A testbed single-shaft turbo-compressor based on Griffith's blade design is tested at the Royal Aircraft Establishment.

* March, 1937: The Heinkel HeS 1 experimental hydrogen fueled centrifugal jet engine is tested at Hirth.
* 27 August 1939: Flight of the world's first turbojet power aircraft. Hans von Ohain's Heinkel He 178 V1 pioneer turbojet aircraft prototype makes its first flight, powered by an He S 3 von Ohain engine.
* 15 May 1941: The Gloster E.28/39 becomes the first British jet-engined aircraft to fly, using a Power Jets W.1 turbojet designed by Frank Whittle and others.
* 1942: Max Bentele discovers in Germany that turbine blades can break if vibrations are in its resonance range, a phenomenon already known in the US from steam-turbine experience.
* 18 July 1942: The Messerschmitt Me 262 first jet-engine flight.
* 1946: Samuel Baylin develops the Baylin Engine, a three cycle internal combustion engine with rotary pistons. A crude but complex example of the future Wankel engine.
* 1951: Engineers for The Texas Company—i.e. now Chevron—develop a four-stroke engine with a fuel injector that employs what was called the Texaco Combustion Process. Unlike normal four-stroke gasoline engines, which used a separate valve for the intake of the air-gasoline mixture, the T.C.P. engine uses an intake valve with a built-in special shroud which delivers the air to the cylinder in a tornado-type fashion; then the fuel is injected and ignited by a spark plug. The inventors claimed that their engine could burn almost any petroleum-based fuel of any octane and even some alcohol-based fuels—e.g. kerosene, benzine, motor oil, tractor oil, etc.—without the pre-combustion knock and the complete burning of the fuel injected into the cylinder. While development was well advanced by 1950, there are no records of the T.C.P. engine being used commercially.
* 1950s: Development begins by US firms of the Free-piston engine concept - a crankless internal-combustion engine.
* 1954: Felix Wankel's first working prototype (DKM 54) of the Wankel engine.

1980 to present

* 2004: Toyota Motor Corp files for patent protection for new form of Scotch yoke engine.
* 2021: During the 2021 United Nations Climate Change Conference 30 states signed a ban of internal combustion engines. Germany and several other participants of the conference did not agree. The Deutz AG presented a new hydrogen-zero-emission-combustion-engine in 2021.
* 2030: The United Kingdom along with the US will become the first to ban the sales of all new vehicles with internal combustion engines.

Engine starting

Early internal combustion engines were started by hand cranking. Various types of starter motor were later developed. These included:

* An auxiliary petrol engine for starting a larger petrol or diesel engine. The Hucks starter is an example
* Cartridge starters, such as the Coffman engine starter, which used a device like a blank shotgun cartridge. These were popular for aircraft engines
* Pneumatic starters
* Hydraulic starters
* Electric starters

Electric starters are now almost universal for small and medium-sized engines, while pneumatic starters are used for large engines.

Modern vs. historical piston engines

The first piston engines did not have compression, but ran on an air-fuel mixture sucked or blown in during the first part of the intake stroke. The most significant distinction between modern internal combustion engines and the early designs is the use of compression of the fuel charge prior to combustion.

The problem of ignition of fuel was handled in early engines with an open flame and a sliding gate. To obtain a faster engine speed Daimler adopted a Hot Tube ignition which allowed 600 rpm immediately in his 1883 horizontal cylinder engine and very soon after over 900 rpm. Most of the engines of that time could not exceed 200 rpm due to their ignition and induction systems.

The first practical engine, Lenoir's, ran on illuminating gas (coal gas). It wasn't until 1883, that Daimler created an engine that ran on liquid petroleum, a fuel called Ligroin which has a chemical makeup of Hexane-N. The fuel is also known as petroleum naphtha.

Otto's first engines were push engines which produced a push through the entire stroke (like a Diesel). Daimler's engines produced a rapid pulse, more suitable for mobile engine use.
