1、汽车发展History of the automobileThe design of the Cugnot Steam Trolley (1769)The history of the automobile begins as early as 1769, with the creation of steam-powered automobiles capable of human transport. In 1806, the first cars powered by internal combustion engines running on fuel gas appeared, whi

2、ch led to the introduction in 1885 of the ubiquitous modern gasoline- or petrol-fueled internal combustion engine. Cars powered by electricity briefly appeared at the turn of the 20th century but largely disappeared from commonality until the turn of the 21st century, when interest in low- and zero-

3、emissions transportation was reignited. As such, the early history of the automobile can be divided into a number of eras based on the prevalent method of automotive propulsion during that time. Later periods were defined by trends in exterior styling and size and utility preferences. Eras of invent

The four-stroke petrol (gasoline) internal combustion engine that constitutes the most prevalent form of modern automotive propulsion is a cre

5、ation of German inventor Nikolaus Otto. The similar four-stroke diesel engine was also invented by a German, Rudolf Diesel. The hydrogen fuel cell, one of the technologies hailed as a replacement for gasoline as an energy source for cars, was discovered in principle by yet another German, Christian

The battery electric car owes its beginnings to Hungarian nyos Jedlik, one of the inventors of the electric motor, and Gaston Plant, who invented the lead-acid battery in 1859.Early automobilesSteam automobilesCugnots steam wagon, the second (1771) versionFerdinand Verbi

Nicolas-Joseph Cugnot demonstrated his fardier vapeur, an experimental steam-driven artillery tractor, in 1770 and 1771. Cugnots design proved to be impract

9、ical and his invention was not developed in his native France, the centre of innovation passing to Great Britain. By 1784, William Murdoch had built a working model of a steam carriage in Redruth, and in 1801 Richard Trevithick was running a full-sized vehicle on the road in Camborne. Such vehicles

10、were in vogue for a time, and over the next decades such innovations as hand brakes, multi-speed transmissions, and better steering developed. Some were commercially successful in providing mass transit, until a backlash against these large speedy vehicles resulted in passing a law, the Locomotive A

11、ct, in 1865 requiring self-propelled vehicles on public roads in the United Kingdom be preceded by a man on foot waving a red flag and blowing a horn. This effectively killed road auto development in the UK for most of the rest of the 19th century. as inventors and engineers shifted their efforts to

12、 improvements in railway locomotives. The law was not repealed until 1896, although the need for the red flag was removed in 1878.In Russia in the 1780s, Ivan Kulibin started working on a human-pedalled carriage with a steam engine. He finished working on it in 1791. Some of its features included a

13、flywheel, brake, gearbox, and bearing, which are also the features of a modern automobile. His design had three roadwheels. Unfortunately, as with many of his inventions, the government failed to see the potential market and it was not developed further. The first automobile patent in the United Sta

14、tes was granted to Oliver Evans in 1789. In 1805, Evans demonstrated his first successful self-propelled vehicle, which not only was the first automobile in the USA, but was also the first amphibious vehicle, as his steam-powered vehicle was able to travel on roadwheels on land, and via a paddle whe

16、 early type of electric motor, created a tiny model car powered by his new motor. In 1834, Vermont blacksmith Thomas Davenport, the inventor of the first American DC electrical motor, installed his motor in a small model car, which he operated on a short circular electrified track. In 1835, Professo

17、r Sibrandus Stratingh of Groningen, the Netherlands and his assistant Christopher Becker created a small-scale electrical car, powered by non-rechargeable primary cells. In 1838, Scotsman Robert Davidson built an electric locomotive that attained a speed of 4 miles per hour (6km/h). In England, a pa

18、tent was granted in 1840 for the use of rail tracks as conductors of electric current, and similar American patents were issued to Lilley and Colten in 1847. Between 1832 and 1839 (the exact year is uncertain), Robert Anderson of Scotland invented the first crude electric carriage, powered by non-re

A Delamare-Deboutteville vehicle was patented and trialled in 1884.About 1870, in Vienna, Austria (then the Austro-Hungarian Empire), inv

23、entor Siegfried Marcus put a liquid-fueled internal combustion engine on a simple handcart which made him the first man to propel a vehicle by means of gasoline. Today, this car is known as the first Marcus car. In 1883, Marcus secured a German patent for a low-voltage ignition system of the magneto

24、 type; this was his only automotive patent. This design was used for all further engines, and the four-seat second Marcus car of 1888/89. This ignition, in conjunction with the rotating-brush carburetor, made the second cars design very innovative.It is generally acknowledged that the first really p

25、ractical automobiles with petrol/gasoline-powered internal combustion engines were completed almost simultaneously by several German inventors working independently: Karl Benz built his first automobile in 1885 in Mannheim. Benz was granted a patent for his automobile on 29 January 1886, and began t

26、he first production of automobiles in 1888, after Bertha Benz, his wife, had proved with the first long-distance trip in August 1888 - from Mannheim to Pforzheim and back - that the horseless coach was absolutely suitable for daily use. Since 2008 a Bertha Benz Memorial Route commemorates this event

27、.Soon after, Gottlieb Daimler and Wilhelm Maybach in Stuttgart in 1889 designed a vehicle from scratch to be an automobile, rather than a horse-drawn carriage fitted with an engine. They also are usually credited as inventors of the first motorcycle in 1886, but Italys Enrico Bernardi, of the Univer

30、 nearly forgotten. In 1891, John William Lambert built a three-wheeler in Ohio City, Ohio, which was destroyed in a fire the same year, while Henry Nadig constructed a four-wheeler in Allentown, Pennsylvania. It is likely they were not the only ones. Veteran eraThe French 1898 Renault VoituretteThe

31、first production of automobiles was by Karl Benz in 1888 in Germany and, under licence from Benz, in France by Emile Roger. There were numerous others, including tricycle builders Rudolf Egg, Edward Butler, and Lon Bolle. Bolle, using a 650cc (40cuin) engine of his own design, enabled his driver, Ja

32、min, to average 45 kilometres per hour (28.0mph) in the 1897 Paris-Tourville rally. By 1900, mass production of automobiles had begun in France and the United States. The first company formed exclusively to build automobiles was Panhard et Levassor in France, which also introduced the first four-cylinder engine. Formed in 1889, Panhard was quickly followed by Peugeot two years later. By the start of the 20th century, the automobile industry was beginning to take off in western Europe, especially in France, where 30,204 were produced in 1903, representing 48.8% of world automobile p
