The colorful history of Car Engine

    The car engine is a device that provides power to the car, and is the heart of the car, which determines the power, economy, stability and environmental protection of the car. According to different sources of power, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids.
Common gasoline engines and diesel engines are reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy for piston movement and output power to the outside. Gasoline engine has high speed, low quality, low noise, easy start, low manufacturing cost; diesel engine has large compression ratio, high thermal efficiency, economic performance and emission performance are better than gasoline engine.
    History development
The engine is the power source of the car. Most automobile engines are thermal power devices, referred to as thermal engines. A thermal engine converts the thermal energy generated by fuel combustion into mechanical energy by means of the state change of the working fluid.
In 1876, German Nicolaus A. Otto invented a reciprocating piston four-stroke gasoline engine based on an atmospheric pressure engine. Due to the four strokes of intake, compression, work and exhaust, the thermal efficiency of the engine has been increased from 11% to 14% of the atmospheric pressure engine, while the quality of the engine has been reduced by 70%.
In 1892, German engineer Rudolf Diesel invented the compression ignition engine (ie diesel engine), achieving the second major breakthrough in the history of internal combustion engines. Due to the high compression ratio and expansion ratio, the thermal efficiency is doubled compared to other engines at that time.
In 1926, the Swiss A. Buchi proposed the exhaust gas turbocharging theory, which uses the energy of exhaust gas discharged from the engine to drive a compressor and supercharge the engine. After the 1950s, exhaust gas turbocharging technology began to be gradually applied to internal combustion engines for vehicles, which greatly improved engine performance and became the third major breakthrough in the history of internal combustion engine development.
In 1956, the German Wankel (Wankel) invented the rotary engine, which greatly increased the engine speed. In 1964, the German NSU company installed a rotary engine on a car for the first time.
In 1967, the German company Bosch (Bosch) first introduced a gasoline injection system (Electronic Fuel Injection, EFI) controlled by an electronic computer, creating a history of the application of electronic control technology to automobile engines. After 30 years of development, the Engine Management System (EMS) with electronic computers as the core has gradually become a standard configuration on automobiles (especially car engines). Due to the application of electronic control technology, the pollutant emissions, noise and fuel consumption of the engine have been greatly reduced, and the power performance has been improved. This has become the fourth major breakthrough in the history of the development of internal combustion engines.
In 1967, the United States conducted a public performance of hydrogen car driving. The hydrogen car can run 121 kilometers for 10 minutes at a speed of 80 kilometers per hour. The car has 19 seats and is manufactured by Billings Corporation of the United States. In 1971, the first bus equipped with a Stirling engine (Strling) began operation. In 1972, Honda Motor Co., Ltd. of Japan sold a Civic brand car equipped with a compound vortex controlled combustion (CVCC, Compound Vertex Controlled Combustion) engine, which was the first shot of a lean gas combustion engine.
In 1977, the first International Electric Vehicle Conference was held in Chicago, USA. During the conference, more than one hundred electric vehicles of various kinds were exhibited. In 1978, Japan successfully researched hybrid vehicles. In August 1979, Brazil manufactured cars that use alcohol as fuel. Brazil is the country that uses alcohol cars the most in the world.
In 1980, Japan successfully developed a liquid hydrogen vehicle. A special storage tank for keeping liquid hydrogen at a low temperature and a certain pressure is installed at the rear. The car used 85 liters of liquid hydrogen and drove 400 kilometers at a speed of 135 kilometers per hour.
In 1980, the United States successfully trial-produced a zinc-chlorine battery electric vehicle.
In 1980, Spain successfully developed a solar car.
In 1980, an engineer in Itzehoe, northwest of Hamburg, West Germany, invented a car powered by calcium carbide (acetylene gas). First, the calcium carbide is turned into gas, and then the gas is burned to propel the jet engine to drive the car. Its speed and safety are no less than that of a gasoline car. 20 kilograms of calcium carbide can make the car travel at least 300 kilometers.
In 1980, John Cooper and Irwin Belen of the University of California began to study “aluminum-burning” electric vehicles.
In 1983, the world’s first automobile equipped with a diesel ceramic engine was successfully tested. The installed engine is developed by Japan’s Kyoto Ceramics Company. Its main components are made of ceramics, which eliminates the need for a cooling system, is light in weight and has significant energy-saving effects. Under the same conditions, it can travel 30% longer than conventional engines.
In 1984, the former Soviet Union developed a dual-fuel car. When a car is started, gasoline is used first, and then natural gas is used exclusively.
In 1984, the American Mobil Petroleum Company’s Amo Kirby Chemical Company developed a synthetic material called Duro Plastic. The company used this plastic to successfully manufacture the world’s first all-plastic automobile engine. The weight is only 84 kg. The American Lola T-616GT car uses this kind of all-plastic engine.
In 1984, Australian engineer Shari Xu successfully developed an OCP engine.
In 1985, Perlanding, Australia, developed a safe, reliable, flexible, high-speed, and non-smoke steam engine car.
In 1986, Japan’s Sanyo Electric Company successfully developed the first solar cell car.
In 1994, David Byrne of the United Kingdom invented another wind car, and it has been put into mass production.
