History of Cars(No Americans):
1680 - Dutch physicist, Christian Huygens designed (but never built) an internal combustion engine that was be fueled with gunpowder.
1807 - Francois Isaac de Rivaz of Switzerland invented an internal combustion engine that used a mixture of hydrogen and oxygen for fuel. Rivaz designed a car for his engine - the first internal combustion powered automobile. However, this was a very unsuccessful vehicle.
1824 - English engineer, Samuel Brown adapted an old Newcomen steam engine to burn gas, and he used it to briefly power a vehicle up Shooter's Hill in London.
1858 - Belgian-born engineer, Jean Joseph Étienne Lenoir invented and patented (1860) a double-acting, electric spark-ignition internal combustion engine fueled by coal gas. In 1863, Lenoir attached an improved engine (using petroleum and a primitive carburetor) to a three-wheeled wagon that managed to complete an historic fifty-mile road trip. (See image at top)
1862 - Alphonse Beau de Rochas, a French civil engineer, patented but did not build a four-stroke engine (French patent #52,593, January 16, 1862).
1864 - Austrian engineer, Siegfried Marcus*, built a one-cylinder engine with a crude carburetor, and attached his engine to a cart for a rocky 500-foot drive. It was the world's first gasoline-powered vehicle. Several year later, Marcus was able to design a vehicle that briefly ran at 10 mph that some historians consider was the forerunner of the modern automobile.
1873 - George Brayton, an American engineer, developed an unsuccessful two-stroke kerosene engine (it used two external pumping cylinders). However, it was considered the first safe and practical oil engine.
1866 - German engineers, Eugen Langen and Nikolaus August Otto improved on Lenoir's and de Rochas' designs and invented a more efficient gas engine.
1876 - Nikolaus August Otto invented and later patented a successful four-stroke engine, known as the ?Otto cycle.?
1876 - The first successful two-stroke engine was invented by Sir Dougald Clerk.
1883 - French engineer, Edouard Delamare-Debouteville, built a single-cylinder four-stroke engine that ran on stove gas. It is not certain if he did indeed build a car, however, Delamare-Debouteville's designs were very advanced for the time - ahead of both Daimler and Benz in some ways at least on paper.
1885 - Gottlieb Daimler invented what is often recognized as the prototype of the modern gas engine - with a vertical cylinder, and with gasoline injected through a carburetor (patented in 1887). Daimler first built a two-wheeled vehicle the "Reitwagen" (Riding Carriage) with this engine and a year later built the world's first four-wheeled motor vehicle.
1886 - On January 29, Karl Benz received the first patent (DRP No. 37435) for a gas-fueled car.
1889 - Daimler built an improved four-stroke engine with mushroom-shaped valves and two V-slant cylinders.
1890 - Wilhelm Maybach built the first four-cylinder, four-stroke engine.
