The first internal combustion engine automobile. p>The birth of the first internal combustion engine automobile
The world's first automobile was successfully developed by German Karl Benz (1844-1929) in October 1885, setting the tone of automobile design in one fell swoop, and even today's automobiles can't jump out of the box. He applied to the German Patent Office for a patent for his automobile invention on January 29, 1886, and on November 2 of the same year, the Patent Office formally approved the issuance of the patent. Therefore, January 29, 1886 is recognized as the birth date of the world's automobiles, and Benz's patent certificate also became the world's first automobile patent certificate.
In fact, before Benz there are some people in the development of automobile engines and cars, the French press as early as 1863 reported the invention of Renault's car, the speed of the car is less than 8km / h, but it is still from Paris to Jovilipoda round trip 18km. 1884, the Frenchman Débutiville use of the combustion engine as a source of power to manufacture a three-wheeled car equipped with a single-cylinder combustion engine and a four-wheeled car with a two-cylinder internal combustion engine.
Long before the invention of the first automobile, many inventions related to it have appeared, such as lead-acid batteries, internal combustion engine ignition, hard rubber solid tires, spring suspension, etc., so the automobile is a combination of many inventions or technologies.
Gottlieb Daimler's four-wheeled car
In 1881, Daimler opened what was then the first so-called automobile factory in partnership with Wilhelm Maybach. On August 15, 1883, Daimler and Maybach invented the gasoline internal combustion engine, and in late 1885, Daimler modified his horse-drawn wagon by adding steering and transmission, installing an internal combustion engine with a power of 1.1kw, and mounting four wheels, which allowed the car to reach speeds of up to 14.4km / h. Daimler was also the first to use the gasoline internal combustion engine in the world.
In 1885, the German Gottlieb Daimler (1843 ~ 1900) invented the first four-wheeled car Benz and Daimler is recognized as the inventor of the internal combustion engine as the power of the modern automobile, their inventions and creations, become the most important milestones in the history of automobile development, and the two of them are therefore honored by the world as the "father of the automobile!
