Did Germans or Americans invent cars?

Germans

In p>1883, Karl Benz, Max Ross and Friedrich Wilhelm Ethelinger * * * founded Benz &; Cie。 On January 29th, 1886, karl benz's automobile obtained the imperial patent certificate (patent number: 37435), and the world's first automobile was officially born.

karl friedrich benz was born in 1844 in Karlsruhe, a craftsman's family. In 186, Karl Ben Ci studied mechanics at Karl Schlueger Comprehensive Science and Technology School, and worked as an apprentice in a machinery factory for three years after graduation. During this period, I met gottlieb daimler, who is 1 years older than him. Later, with the help of his teacher, he made an engine. He studied Otto's engine, and on December 31, 1879, he made a new gas engine with a single cylinder, with a speed of about 2 rpm and a power of about .75 kW. But he didn't get a patent because the engine couldn't be used. Karl benz modified Otto's four-stroke engine and adopted Alexis von Bismarck engine. Modification of Otto engine will infringe on the patent right of Otto engine. Fortunately, the German court cancelled the patent right of Otto four-stroke engine and only recognized the four-stroke engine produced in Ben Ci.

Ben Ci's fortunes have changed. He improved the gas engine into a gasoline engine. After repeated tests, on January 29th, 1886, the world's first three-wheeled car invented by karl benz won the "automobile manufacturing patent". This car uses a single-cylinder engine for the first time in automobile history. He installed a slide valve in front of the air inlet and a spark plug with a high-voltage ignition coil, and used a surface carburetor to generate mixed gas, while placing the governor on the intake manifold. Ben Ci's single-cylinder engine has a displacement of .954 liter, a rotating speed of 25 rpm and an output power of .49 kW. This car first ran on the streets of Mannheim in June 1886.

The speed of this car in Ben Ci is 5m per hour. The car relies on the belt to transmit power to the driving wheels, and the belt can be slipped between pulleys of different sizes to change the speed. Umbrella differential gear was first used in the car to compensate the difference of driving distance between the two driving wheels caused by the change. Car frames are made of steel pipes, and wheels are made of copper wire spokes.
