Turbocharging is the most common exhaust gas-driven air compressor technology today, and the turbo logo of turbocharged models makes many car fans unable to stop. But as for the inventor of turbocharging, everyone has different opinions. As an automobile industry technology, most people think that the invention of turbocharging originated from major automobile countries such as Germany, Japan, and the United States. But in fact, turbocharging Pressure comes from Switzerland.
As early as the early days of the automobile, Daimler and Diesel had begun to study the method of compressing air to increase engine power. It was not until 1905 that Swiss engineer Dr. Alfred J. Posey first proposed the concept of turbocharging in Winterthur, Switzerland. On November 16 of the same year, he was awarded the patent by the German Patent Office. Patent No. 204630 "Internal Combustion Engine Auxiliary Supercharger Technology" officially means the birth of turbocharging technology.
In 1914, the First World War officially broke out, and turbocharging technology officially began to be applied. Due to the rapid increase in the number of aircraft and tanks at that time, in order to have a better advantage on the battlefield, European aerospace engineers took the lead in testing turbocharging technology on their own fighters. In 1918, American engineers installed a turbocharger on the famous "Liberty" V12-cylinder aeroengine, which greatly increased the power of the aircraft engine. As a result, turbocharging came into play in the military field.
However, until the end of World War II, turbocharging technology had not yet been applied in the automotive field. The main reason was that the car engine speed at that time was low, resulting in poor control of the turbocharger blades controlled by exhaust gas, which would block the engine air intake, resulting in turbo lag and knocking. It was not until 1962 that General Motors installed a turbocharger on its mass-produced model Oldsmobile Jetfire Rocket for the first time. However, because the V8 engine and turbocharger in this car work together, parts of the supercharger are often burned out.
It was not until the 1970s that turbocharging technology ushered in a new turning point. In 1973, due to the outbreak of the oil crisis and the skyrocketing price of gasoline and diesel worldwide, turbocharging technology once again It entered the attention of automobile manufacturers, but at that time, no automobile manufacturer had yet developed mature turbocharging technology. Until 1977, Swedish SAAB Saab launched the SAAB99 model equipped with mature turbocharging technology. The SAAB99 model was equipped with a 2.0-liter turbocharged engine, which increased the power by 23% and the torque by 45%.
Due to the continuous strengthening of EU emission regulations in recent years, car manufacturers in EU countries have had to step up the research and development and promotion of turbocharging. However, it was only in 10 years that domestically produced models began to gradually become popular with turbocharged models. of manufacturing. With the maturity of turbocharging technology today, models equipped with turbocharging technology can be seen everywhere on the streets. Coupled with the birth of electric turbines, the phenomenon of turbo lag has been solved very well, making more car manufacturers willing to use.
