Turbine interface patent

Turbocharging is the most common exhaust gas-driven air compressor technology at present, and the turbine logo equipped with turbocharged models makes many fans want to stop. But people have different opinions about the inventor of turbocharging. As a technology in the automobile industry, most people think that the invention of turbocharging originated from Germany, Japan, the United States and other automobile powers, but in fact turbocharging originated from Switzerland.

As early as the early days of automobile, Daimler and Dissel had begun to study the method of compressing air to increase engine power. Until 1905, Swiss engineer Alfred? Alfred J Posey first put forward the concept of turbocharging in winterthur, Switzerland, and was awarded the patent No.204630 "Turbocharging Technology for Internal Combustion Engine" by the German Patent Office in June 165438+ 10/6 of the same year, which officially meant the birth of turbocharging technology.

19 14 with the official outbreak of world war I, turbocharging technology was officially applied. Due to the sharp increase in the number of aircraft and tanks at that time, in order to have a better advantage on the battlefield, European aviation engineers took the lead in testing turbocharging technology on their fighters. 19 18, American engineers installed a turbocharger on the famous "Freedom" V 12 cylinder aero-engine, which greatly improved the power of the aero-engine, and turbocharging also showed its talents in the military field.

However, until the end of World War II, turbocharging technology has not been applied in the automotive field. The main reason is that the speed of the automobile engine at that time was low, which led to the poor control of the turbocharging blades for exhaust gas control, which would hinder the intake of the engine and lead to turbo lag and knock. It was not until 1962 that General Motors of the United States first installed a turbocharger on its production model Oldsmobile Jetfire. Rockets. But because of the combination of V8 engine and turbocharger, the parts of turbocharger are often burned out.

Until the 1970s, turbocharging technology ushered in a new turning point. 1973, due to the oil crisis, gasoline and diesel prices soared worldwide, and turbocharging technology once again entered the sight of automobile manufacturers, but no automobile manufacturer developed mature turbocharging technology at that time. Until 1977, SAAB in Sweden introduced a mature Saab 99 model equipped with turbocharging technology. The power of the 2.0-liter turbocharged engine of this Saab 99 model increased by 23% and the torque increased by 45%.

However, due to the continuous strengthening of EU emission regulations in recent years, automobile manufacturers in EU countries have to step up the research and development and promotion of turbocharged vehicles, and domestic models have gradually become popular at 10. With the maturity of turbocharging technology, vehicles equipped with turbocharging technology can be seen everywhere in the streets. Coupled with the birth of electric turbine, the phenomenon of turbine hysteresis has been well solved, making more automobile manufacturers willing to use it.
