The invention of the internal combustion engine is most probably the result of the developments of several individuals. Around 1780, Dutch scientist Christiaan Huygens built an engine that used gunpowder as a fuel, but this engine was far too dangerous to be practical. His assistant, Denis Papin, also experimented with developing an internal combustion engine, building a simple steam-powered device around 1790. Again, this engine was not practical, and not until the early nineteenth century did the development of a practical internal combustion engine become the quest of numerous inventors.

Before then, the steam engine was the power plant of choice. By 1770, the steam engine had been developed to the point that the French engineer Nicolas Cugnot used one to successfully propel a three-wheeled vehicle, and steam power reigned supreme in industry for nearly a century.

Early in the industrial revolution, inventors struggled to develop an engine in which compressed fuel could be burned within a cylinder housing a piston, thus capturing a much greater amount of the potential energy of the fuel. French physicist Nicholas Carnot (1796-1832) published a book in 1824 in which he set out the principles of an internal combustion engine which would use a flammable mixture of gas vapor and air. Basing his work on Carnots principles, another Frenchman, Jean-Joseph-Д‰ttien Lenoir, presented the world with its first workable internal combustion engine in 1859. Lenoirs motor was a two-cycle, one-cylinder engine with slide valves and used illuminating gas (coal gas) as a fuel; it also used an electrical charge, supplied by a battery, to ignite the gas after it was drawn into the cylinder. Lenoir sold several hundred of his engines, and he adapted his engine to power a carriage; consequently, he is credited with inventing the first gas-powered automobile. Lenoirs primitive two-stroke design, however, was inefficient because each back-and-forth motion of the piston must draw in the fuel, burn it, and expel the burnt gases.

Another Frenchman, Alphonse Beau de Rochas, recognized the shortcomings of Lenoirs engine, and, in 1862, he proposed refinements to the two-stroke cycle as well as designs for a four-stroke engine that would overcome many problems associated with the gas engines of the time. The four-stroke engine doubles the motion of the piston required to accomplish intake, compression, and exhaust, and, by doing so, greatly increases the efficiency of the engine. Early French theory and practice were combined by two Germans, Nikolaus Otto and Eugen Langen, into a two-cycle engine that was considerably more efficient than the Lenoir engine. Introduced in 1867, Otto and Langens engine achieved greater efficiency by compressing the gas before combustion, a refinement lacking in Lenoirs engine. The two Germans first workable four-stroke internal combustion engine was patented in 1876 and was tremendously successful, selling over 50,000 engines in the 17 years following its introduction. The “Otto-cycle” four-stroke engine was the development that made modern automobiles, aircraft, motorcycles, and other vehicles practical.

Gottlieb Daimler, who once worked for Otto, made several refinements to Ottos engine. He devised a cam system so that engines with more than one cylinder could be ganged together. Daimlers two-cylinder gas engine was
