The hottest 100 year history of Turbocharging Tech

One hundred years' history of turbocharging technology

turbo charging is not a new term for the world automotive industry. Hanzhiyu, a professor and engine expert at Hunan University, told us that the birth of the turbocharging concept has a history of more than 100 years. Relevant data show that in 1905, Dr. Alfred J Buchi, chief engineer of Sulzer brothers R & D company, first proposed the concept of turbocharging in Winterthur, Switzerland, and was granted the patent No. 204630 of internal combustion engine auxiliary supercharger technology by the German Patent Office on November 16 of that year, This marks the official birth of the implementation brand of the project of turbocharging technology 5 computer (including uninterrupted power supply) and 1 Lenovo product. Posey is also recognized as the founder of turbocharging technology

1912, the world's first exhaust driven supercharger officially came out. However, this technology was not initially used in the automotive industry, but in the marine and aviation fields. In 1923, the German Ministry of transport built two ships using turbocharging technology, which increased the maximum power output of the ship's 10 cylinder engine from 1750 HP to 2500 HP. The large-scale production of turbochargers appeared during World War II, and was first used in military aircraft by the United States

1961, the car began to install the supercharger tentatively, but the effect after installation was not ideal because of the huge pressure and heat generated at the moment because of the higher requirements for the integration and efficiency of the universal tensile testing machine. Saab is the first automobile manufacturer to successfully apply turbochargers to automotive products in batches. Saab 99 models equipped with turbocharged engines sold nearly 590000 vehicles from 1969 to 1984, which is enough to show the market's affirmation of this technology. Insiders generally believe that Saab has really matured the application of turbocharging technology in automotive engines, announcing the birth of a new era in the automotive industry. Turbocharging technology has rewritten the traditional concept that the displacement determines the power

in the history of turbocharging technology development in the last century, BMW's turbo200 and Porsche's 911turbo are both popular models pursued by consumers. In China, Volkswagen took the lead in introducing the car turbocharging technology. At present, the 2.0tsi (turbocharged direct injection engine) engine used in many models has won the annual maximum range engine award of 1.8 ~ 2.0L displacement level in the review panel of nearly 60 top automotive disciplines in about 30 countries for several consecutive years (2005, 2006 and 2007). The review panel believes that the engine has Environmental protection has been balanced

according to hanzhiyu, turbocharging technology has developed for a long time in China, but it is mainly used in diesel engines, and gasoline engines are less used in this technology. In the early 1980s, when I was still in college, a professor in the University was developing a turbocharged gasoline engine for a domestic automobile enterprise. The purpose was different from that at present. At that time, when the car was driving on the plateau, due to the thin air, the output torque and power decreased significantly. The application of turbocharging technology can help the engine recover power and torque. However, at that time, the speed of gasoline engine was relatively low, and the technical level of turbine was not high, which could not be compared with today. Hanzhiyu recalled

it is understood that at present, except for some relatively backward agricultural vehicles, turbocharging technology is applied to almost all diesel engines in China. With the goal of energy saving and emission reduction, small displacement turbocharged direct injection gasoline engine will become the mainstream in China. Hanzhiyu disclosed that he is in charge of relevant technology research and development projects, and several domestic automobile enterprises with independent brands are also making relevant technology reserves
