German karl benz successfully developed the world's first three-wheeled car in 1885+00. 1886 65438+1October 29th applied to the German Patent Office for an automobile invention patent, and in the same year165438+1October 2nd was officially approved by the Patent Office. This is also the world's first automobile patent certificate. So1886 65438+1October 29th is recognized as the world automobile birth day.
The tricycle designed by karl benz uses a two-stroke single-cylinder gasoline engine with 0.9 horsepower. This tricycle has some characteristics of modern cars, such as spark ignition, water cooling cycle, rear wheel drive, front wheel steering and brake handle. In the early days of my invention, people didn't think highly of Ben Ci's cars. It was not until my wife drove 100 kilometers to my grandmother's house that the reliability was verified and people gradually recognized it.
Moreover, before Ben Ci, few people developed automobile engines and automobiles, and many automobile-related inventions had already existed, such as lead-acid batteries, ignition devices for internal combustion engines, hard rubber solid tires and so on. So the car is a comprehensive application of many inventions or technologies.
As the power source of traditional fuel vehicles, internal combustion engines are the most important structural components of automobiles. 1670, the Dutch physicist huygens invented a machine that uses gunpowder to burn and expand in the cylinder to push the piston to do work, which is the prototype of modern internal combustion engine. After more than 200 years of exploration, the German inventor Otto designed and manufactured the first four-stroke internal combustion engine in 1876. Karl benz put this internal combustion engine on a three-wheeled carriage and invented the automobile. Although the technology is developing rapidly at present, the working principle of internal combustion engine still comes from Otto's internal combustion engine. Million car purchase subsidy
