Since the automobile was born at the end of last century, it has experienced more than one hundred years of ups and downs. The first three-wheeled car made in karl benz has been running at the speed of 100km/h, and now a super sports car has been born. It only takes a little more than three seconds to accelerate from zero to100 km/h. In this century, the speed of automobile development is so amazing! At the same time, the automobile industry has also created a number of giants, who have created some famous companies that play an important role in the economies of various countries, such as General Motors, Ford, Toyota and Honda. Let's look back at this period of history, savor the bitterness and joy, and experience all kinds of joys and dreams brought by cars. ...
Cars, like computers and other modern cutting-edge tools, were not invented by a person sitting there. Cars at the beginning of invention are not what they are now. If I could see the car at that time, I might think it wasn't a car. The development of automobiles also has a long history. Generally speaking, the history of automobile development can be divided into three stages: before the invention of the steam engine, the steam automobile came out and the automobile began to be produced on a large scale.
The initial work and labor of human beings were completely done by themselves. There are no cars or engines. If there is, the engine of human shares was used before the use of cattle and horses. Slave is a kind of "biological engine". With the progress and development of mankind, people's understanding of nature is getting deeper and deeper, and their ability to use and transform nature is strengthening day by day. People not only use human and animal power, but also know how to use water power and wind power.
1705, newcomen invented a practical steam engine for the first time, which did not rely on people and animals to do work, but on machinery. This kind of steam engine was used to drive machinery, resulting in the epoch-making first industrial revolution. With the birth of steam-driven machinery, namely automobile, human society began the endless development of automobile.
1769, the Frenchman N.J. Cugnot made the world's first steam-driven tricycle. In 1804, Trouilh Sike designed and manufactured another steam car, which also pulled 10 tons of goods and ran on the railway for 15.7 kilometers.
183 1 year, ColdsworthyGur-ney of the United States put into transport steam cars, and there is regular transport service between Gestia and Luo Teng Hamm, which is15km away. This transport plane will take about 45 minutes to complete the journey. In the next three years, steam-driven buses also appeared on the streets of London. When this heavy monster ran in English towns, it caused a great sensation. Speaking of it, this kind of car is heavier and slower than the existing road. It often crashes into unpaved roads, causing various accidents. At that time, some citizens called for a ban on this kind of car. To this end, Britain has enacted the so-called "Red Flag Law". Ironically, due to the implementation of this law, Britain later fell far behind other industrial countries in the start of manufacturing cars.
Because the steam car itself is stupid and heavy, and it is hot and dirty when riding in a steam car, in order to improve this kind of engine, Etienne Renault made an engine at 1800, which is different from the steam engine (that is, the external combustion engine) in that the fuel burns outside, so that the fuel burns inside the engine. Later, people called this engine an internal combustion engine.
1876, CountNicholasOtto invented that the mixture of air and gasoline was compressed and then ignited after entering the cylinder, which improved the efficiency of the engine. This engine has four strokes: intake, compression, work and exhaust. To commemorate Otto's invention, people renamed this cycle Otto cycle.
1879, German engineer KartBenz successfully tested the two-stroke experimental engine for the first time. 1Established "Mercedes-Benz Company and Rhine Gas Engine Factory" in June, 883. 1In June, 885, he manufactured the first patented Mercedes-Benz motor vehicle in Mannheim, which was a three-wheeled vehicle with a two-stroke single-cylinder gasoline engine and 0.9 horsepower. This car has some basic features of modern cars, such as spark ignition, water cooling cycle and steel tube frame.
I hope my answer is helpful to you, thank you!
