History of the internal combustion engine
Various scientists and engineers contributed to the development of internal combustion engines. In 1791 2, John Barber developed a 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 (gasoline) , and built an engine around that time. In 1798, John Stevens designed the first American internal combustion engine. In 1807, Swiss engineer François Isaac de Rivaz built an internal combustion engine ignited by electric spark. In 1823, Samuel Brown patented the first internal combustion engine to be applied industrially.
In 1860, Belgian Jean Joseph Etienne Lenoir produced a gas-fired internal combustion engine. In 1864, Nikolaus Otto patented the first atmospheric gas engine. In 1872, American George Brayton invented the first commercial liquid-fueled internal combustion engine. In 1876, Nikolaus Otto, working with Gottlieb Daimler and Wilhelm Maybach, patented the compressed charge, four-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.
Prior to 1860
- 3rd century: The earliest evidence of a crank and connecting rod mechanism dates to the 3rd century AD Hierapolis sawmill in Asia Minor (Turkey) as part of the Roman Empire.
- 5th century: Roman engineers documented several crankshaft-connecting rod machines used for their sawmills.
- 9th century: The crank appears in the mid-9th century in several of the hydraulic devices described by the Banū Mūsā brothers in their Book of Ingenious Devices.
- In 1206, al-Jazari invented an early crankshaft, which he incorporated with a crank-connecting rod mechanism in his twin-cylinder pump. Like the modern crankshaft, Al-Jazari's mechanism consisted of a wheel setting several crank pins into motion, with the wheel's motion being circular and the pins moving back-and-forth in a straight line. The crankshaft described by al-Jazari transforms continuous rotary motion into a linear reciprocating motion.
- 17th century: Samuel Morland experiments with using gunpowder to drive water pumps.
- 17th century: Christiaan Huygens designs gunpowder to drive water pumps, to supply 3000 cubic meters of water/day for the Versailles palace gardens, essentially creating the first idea of a rudimentary internal combustion piston engine.
- 1780s: Alessandro Volta built a toy electric pistol in which an electric spark exploded a mixture of air and hydrogen, firing a cork from the end of the gun.
- 1791: John Barber receives British patent #1833 for A Method for Rising Inflammable Air for the Purposes of Producing Motion and Facilitating Metallurgical Operations. In it he describes a turbine.
- 1794: Robert Street built a compressionless engine. He was also the first to use liquid fuel in an internal combustion engine.
- 1794: Thomas Mead patents a gas engine.
- 1798: John Stevens builds the first double-acting, crankshaft-using internal combustion engine.
- 1801: Philippe LeBon D'Humberstein comes up with the use of compression in a two-stroke engine.
- 1807: Nicéphore Niépce installed his "moss, coal-dust and resin" fueled Pyréolophore internal combustion engine in a boat and powered up the river Saône in France. A patent was subsequently granted by Emperor Napoleon Bonaparte on 20 July 1807.
- 1807: Swiss engineer François Isaac de Rivaz built an internal combustion engine powered by a hydrogen and oxygen mixture, and ignited by electric spark. (See 1780s: Alessandro Volta above.)
- 1823: Samuel Brown patented the first internal combustion engine to be applied industrially. It was compressionless and based on what Hardenberg calls the "Leonardo cycle", which, as the name implies, was already out of date at that time.
- 1824: French physicist Sadi Carnot established the thermodynamic theory of idealized heat engines.
- 1826 April 1: American Samuel Morey received a patent for a compressionless "Gas or Vapor Engine." This is also the first recorded example of a carburetor.

- 1838: A patent was granted to William Barnett, UK patent no. 7615 April 1838. According to Dugald Clerk, this was the first recorded use of in-cylinder compression.
- 1853–1857: Eugenio Barsanti and Felice Matteucci invented and patented an engine using the free-piston principle in an atmospheric two cycle engine.
- 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.
- 1857: Eugenio Barsanti and Felice Matteucci describe the principles of the free piston engine where the vacuum after the explosion allows atmospheric pressure to deliver the power stroke (British patent no. 1625).
- 1860: Belgian Jean Joseph Etienne Lenoir (1822–1900) produced a gas-fired internal combustion engine 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. This was the first internal combustion engine to be produced in numbers.
- 1861: Nikolaus Otto builds a copy of the Lenoir engine.
- 1862: Nikolaus Otto attempts the construction of the compressed charge four cycle engine, and fails.
- 1862: The earliest confirmed patent of the 4-cycle engine, by Alphonse Beau de Rochas. This was principle only, there was NO engine built to prove the concept.
- 1862: The German Nikolaus Otto begins to manufacture a no compression gas Lenoir engine with a free piston.
- 1864: Nikolaus Otto, patented in England and other countries his first atmospheric gas engine. Otto was the first to build and sell this type of compressionless engine designed with an indirect-acting free-piston, whose great efficiency won the support of Eugen Langen and then most of the market, which at that time was mainly for small stationary engines fueled by lighting gas. Eugen Langen collaborated with Otto in the design and they began to manufacture it in 1864.
- 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.
- 1870: In Vienna, Siegfried Marcus put the first mobile gasoline and the first modern internal combustion engine on a handcart.
- 1872: In America George Brayton invented Brayton's Ready Motor and went into commercial production, this used constant pressure combustion, and was the first commercial liquid fuelled internal combustion engine.
- 1876: Nikolaus Otto, working with Gottlieb Daimler and Wilhelm Maybach, patented the compressed charge, four-stroke engine. The German courts, however, did not hold his patent to cover all in-cylinder compression engines or even the four-stroke cycle, and after this decision, in-cylinder compression became universal.
- 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 internal combustion engine, a reliable two-stroke gas engine. Later, Benz designed and built his own four-stroke engine that was used in his automobiles, which were developed in 1885, patented in 1886, and became the first automobiles in production.
- 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 
- 1887: Gustaf de Laval introduces the de Laval nozzle
- 1889: Félix Millet begins development of the first vehicle to be powered by a rotary engine in transportation history.
- 1891: Herbert Akroyd Stuart built his oil engine, leasing rights to Hornsby of England to build them. They built the first cold-start compression-ignition engines. In 1892, they installed the first ones in a water pumping station. In the same year, an experimental higher-pressure version produced self-sustaining ignition through compression alone.
- 1892: Rudolf Diesel developed the first compressed charge, compression ignition engine .
- 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.
- 1897: Robert Bosch was the first to adapt a magneto ignition to a vehicle engine.
- 1898: Fay Oliver Farwell designs the prototype of the line of Adams-Farwell automobiles, all to be powered with three or five cylinder rotary internal combustion engines.
- 1900: Rudolf Diesel demonstrated the diesel engine in the 1900 Exposition Universelle (World's Fair) using peanut oil fuel (see biodiesel).
- 1900: Wilhelm Maybach designed an engine built at Daimler Motoren Gesellschaft—following the specifications of Emil Jellinek—who required the engine to be named Daimler-Mercedes after his daughter. In 1902 automobiles with that engine were put into production by DMG.
- 1903: Konstantin Tsiolkovsky begins a series of theoretical papers discussing the use of rocketry to reach outer space. A major point in his work is liquid fueled rockets.
- 1903: Ægidius Elling builds a gas turbine using a centrifugal compressor which runs under its own power. By most definitions, this is the first working gas turbine.
- 1905: Alfred Buchi patents the turbocharger and starts producing the first examples.
- 1903–1906: The team of Armengaud and Lemale in France build 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: René Lorin patents a design for the ramjet engine.
- 1916: Auguste Rateau suggests using exhaust-powered compressors to improve high-altitude performance, the first example of the turbocharger.
- 1920: William Joseph Stern reports to the Royal Air Force that there is no future for the turbine engine in aircraft. He bases his argument on the extremely low efficiency of existing compressor designs. Due to Stern's eminence, his paper is 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 is introduced by Swedish engineer Jonas Hesselman represented 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. In it he 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, going on to mathematically demonstrate that a practical engine is definitely possible and showing 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.
- 1929: Frank Whittle's thesis on jet engines is published
- 1930: Schmidt patents a pulse-jet engine in Germany.

- 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 the 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—developed a four stroke engine with a fuel injector that employed what was called the Texaco Combustion Process, which unlike normal four stroke gasoline engines which used a separate valve for the intake of the air-gasoline mixture, with the T.C.P. engine the intake valve with a built in special shroud delivers the air to the cylinder in a tornado type fashion and then the fuel is injected and ignited by a spark plug. The inventors claimed their engine could burn on 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 which is a crankless internal combustion engine.
- 1954: Felix Wankel's first working prototype DKM 54 of the Wankel engine
1980 to present

- 2004: Hyper-X first scramjet to maintain altitude
- 2004: Toyota Motor Corp files for patent protection for new form of Scotch yoke engine.
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 naptha.
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.
