The Internal Combustion Engine
The Internal-Combustion Engine
The first internal-combustion engine was designed by the Dutch scientist Christiaan Huygens in 1678; it was to have been fueled with gunpowder, but it was never built. About 1860 a French inventor, Lenoir, built the first practical internal-combustion engine; it burned illuminating gas. In 1866 two German engineers, Eugen Langen and Nikolaus August Otto, developed a more efficient gas engine, and in 1876 Otto built a four-cycle engine, a prototype of the so-called Otto-cycle engines used in most modern automobiles and airplanes
The high-speed internal-combustion motor of the German engineer Gottlieb Daimler revolutionized the automobile industry. His four-cycle, single-cylinder motor, patented in 1887, achieved speeds many times those of any previous engine, thereby producing many times the power for the same weight. In 1889 he developed a two-cylinder engine that gave still greater power; the cylinders were in a V-type configuration. This engine design was adopted by a French manufacturer, Emile Levassor, who launched experiments in 1891 that subsequently led his firm, Panhard et Levassor, into automobile manufacture. Levassor's first automobile, produced in 1894, not only incorporated the Daimler engine but also was the first car in which the working parts were arranged in the operational sequence still used in present-day models. That is, the engine was in front, followed by the clutch, gearbox, propeller shaft, and differential and driving axle. The superiority of the high-speed Daimler engine over the then highly developed steam engine was conclusively demonstrated at the famous Paris-Bordeaux Race of 1895. The first car, propelled by a Daimler engine, came in six hours ahead of the second car, and the next three cars to finish were all propelled by Daimler engines. Another pioneer with the gasoline engine was the German engineer Karl Benz, who in 1885, working independently of Daimler, produced a mechanically propelled tricycle.
In the United States, pioneer automobile manufacturers were very active in the 1890s. Charles Edgar Duryea and his brother Frank Duryea brought out their horseless carriage in 1892-1893; the design of 1894 had two cylinders. Elwood Haynes constructed his automobile about the same time, and Alexander Winton produced his in 1896. Henry Ford produced his first car, an experimental model, in 1896.
