Nicolaus August Otto
Nicolaus August Otto (10 June 1832 – 26 January 1891) was a German engineer who successfully developed the compressed charge internal combustion engine which ran on petroleum gas and led to the modern internal combustion engine. The Association of German Engineers (VDI) created DIN standard 1940 which says "Otto Engine: internal combustion engine in which the ignition of the compressed fuel-air mixture is initiated by a timed spark", which has been applied to all engines of this type since. Biography Nicolaus August Otto was born on 10 June 1832 in Holzhausen an der Haide, Germany. He was the youngest of six children. His father died in 1832. He began school in 1838. After six years of good performance he moved to the high school in Langenschwalbach until 1848. He did not complete his studies but was cited for good performance. His main interest in school had been in science and technology but he graduated after three years as a business apprentice in a small merchandise ...

Engine
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form; thus heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine in wh ...

Automobile
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people rather than cargo. There are around one billion cars in use worldwide. The French inventor Nicolas-Joseph Cugnot built the first steam-powered road vehicle in 1769, while the Swiss inventor François Isaac de Rivaz designed and constructed the first internal combustion-powered automobile in 1808. The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively. Cars were rapidly adopted in the US, where they replac ...

Otto Engine
The Otto engine is a large stationary single-cylinder internal combustion engine, internal combustion four-stroke engine, designed by the German Nicolaus Otto. It was a low-RPM machine, and only fired every other stroke due to the Otto cycle, also designed by Otto. Types Three types of internal combustion engines were designed by German inventors Nicolaus Otto and his partner Eugen Langen. The models were a failed 1862 compression engine, an 1864 atmospheric engine, and the 1876 Otto cycle engine known today as the ''petrol engine''. The engines were initially used for stationary installations, as Otto had no interest in transportation. Other makers such as Daimler perfected the Otto engine for transportation use."Nikolaus August Otto: Inventor Of ...

Four Stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing a partial vacuum (negative pressure) in the cylinder through its downward motion. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are closed during this stage. #Combustion: Also known as power or ignition. This is ...

Gottlieb Daimler
Gottlieb Wilhelm Daimler (; 17 March 1834 – 6 March 1900) was a German engineer, industrial designer and industrialist. He was a pioneer of internal-combustion engines and automobile development. He invented the high-speed liquid petroleum-fueled engine. Daimler and his lifelong business partner Wilhelm Maybach were two inventors whose goal was to create small, high-speed engines to be mounted in any kind of locomotion device. In 1883 they designed a horizontal cylinder layout compressed charge liquid petroleum engine that fulfilled Daimler's desire for a high speed engine which could be throttled, making it useful in transportation applications. This engine was called Daimler's Dream. In 1885 they designed a vertical cylinder version of this engine which they subsequently fitted to a two-wheeler, the first internal combustion motorcycle which was named the Reitwagen, Petroleum Reitwagen (Riding Car) and, in the next year, to a Coach (carriage), coach, and a boat. Daimler call ...

Felice Matteucci
Felice Matteucci (February 12, 1808 – September 13, 1887) was an Italian hydraulic engineer who co-invented an internal combustion engine with Eugenio Barsanti. 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 Gases", as documented by the Fondazione Barsanti e Matteucci. Biography Born in Lucca, Tuscany, Matteucci studied hydraulic and mechanical engineering, first in Paris, then in Florence. In 1851 he met Father Barsanti and appreciated his ideas for a new type of engine. They worked together to turn the primary concept into a manufacturable item, eventually developing a model suitable for mass production. Its construction was entrusted to Bauer & Co. of Milan, a company also known as Helvetica, which delivered the motor at the beginning of 1863. The success of the engine, which was much more efficient tha ...

Eugenio Barsanti
Eugenio Barsanti (12 October 1821 – 19 April 1864), also named Nicolò, was an Italian engineer and Catholic priest who, together with Felice Matteucci, invented the first 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", as documented by the Fondazione Barsanti e Matteucci. Biography Barsanti was born in Pietrasanta, Grand Duchy of Tuscany, Tuscany. Lean and short of stature, he studied in a Catholic scientific-oriented institute near Lucca, in Tuscany, and entered the novitiate of the Piarist Fathers or Scolopi, who were known for being open to scientific study, in Florence in 1838. In 1841 Barsanti began teaching in the ''Collegio San Michele'', situated in Volterra. Here, during a lecture describing the explosion of mixed hydrogen and air, he realised the poten ...

Atmospheric Engine
The atmospheric engine was invented by Thomas Newcomen in 1712, and is sometimes referred to as the Newcomen fire engine (see below) or Newcomen engine. The engine was operated by condensing steam being drawn into the cylinder, thereby creating a partial vacuum which allowed atmospheric pressure to push the piston into the cylinder. It is significant as the first practical device to harness steam to produce mechanical work. Newcomen engines were used throughout Britain and Europe, principally to pump water out of mines. Hundreds were constructed during the 18th century. James Watt's later engine design was an improved version of the Newcomen engine that roughly doubled fuel efficiency. Many atmospheric engines were converted to the Watt design. As a result, Watt is today better known than Newcomen in relation to the origin of the steam engine. Precursors Prior to Newcomen a number of small steam devices of various sorts had been made, but most were essentially novelties.

Eugen Langen
Carl Eugen Langen (9 October 1833 in Cologne – 2 October 1895 in Elsdorf) was a German entrepreneur, engineer and inventor, involved in the development of the petrol engine and the Wuppertal Suspension Railway. In 1857 he worked in his father's sugar factory, JJ Langen & Söhne, and after extensive technical training at the Polytechnic institute in Karlsruhe, patented a method for producing sugar cubes. In 1870 he co-founded Pfeifer & Langen, still in operation today. He sold this method in 1872 to Sir Henry Tate of England, founder of the Tate Gallery in London. Otto and Langen In 1864, Langen met Nicolaus August Otto who was working to improve the gas engine invented by Belgian Etienne Lenoir. The technically–trained Langen recognized the potential of Otto's development, and one month after the meeting, founded the first engine factory in the world, NA Otto & Cie. At the 1867 Paris World Exhibition, their improved engine received the Grand Prize. Deutz After this f ...
