In 1879, German engineer Karl Benz successfully tested a two-stroke experimental engine for the first time. In October 1883, he founded the "Benz Company and Rhine Gas Engine Factory". In 1885, he made the first Benz patented motor vehicle in Mannheim. The vehicle was a three-wheeled vehicle, using a two-wheeled engine. Stroke single cylinder 0.9 HP gasoline engine. This car has some basic features of modern cars, such as spark ignition, water cooling cycle, steel tube frame, leaf spring suspension, rear-wheel drive, front-wheel steering and brake handle. On January 29, 1886, German engineer Carl Benz applied for a patent for his motor vehicle. In November of the same year, Karl Benz's three-wheeled motor vehicle obtained the German patent (Patent No.: 37435a). This is recognized as the world's first modern car. Due to the above reasons, people generally regard 1886 as the first year of the automobile, and some scholars regard the year when Carl Benz built the first three-wheeled automobile (1885) as the birth year of the automobile. In 1829, James of England invented a steam car with a speed of 25 kilometers per hour, which could be used as a large sedan. The cars had bulky boilers and lots of coal, emitted black smoke, polluted the streets, made a rumbling noise, and were prone to accidents. In 1860, French worker Runoyard invented the internal combustion engine and used a gas engine of about 1 horsepower to drive a car, but the effect was not good. However, cars were created under the influence of this internal combustion engine. Reference for the above content: Baidu Encyclopedia-Automotive
