The main function of turbocharging is to increase the air intake of the engine, thus improving the power and torque of the engine and making the car more dynamic. After the engine is equipped with turbocharger, its maximum power can be increased by 40% or even higher than that without turbocharger.
This means that the same engine can output more power after being supercharged. Take our most common 1.8T turbocharged engine as an example. After supercharging, the power can reach the level of 2.4L engine, but the fuel consumption is not much higher than that of 1.8L engine. Another level is to improve fuel economy and reduce exhaust emissions.

Development history
Who is the inventor of turbocharger? It is generally recognized as Bosch, a Swiss engineer, who declared this patent in 1905.
It was mainly used for aircraft engines and tank engines at that time. It was not until 196 1 that General Motors of the United States installed a turbocharger on a certain model it produced. The 1970s became the turning point of turbocharging, and Porsche 9 1 1 with supercharged engine came out.
However, SAAB in Sweden is the only company that rejuvenates turbocharging technology. The Saab 99 launched in 1977 spread the turbocharging technology more widely, but the turbocharger at that time was only assembled on the gasoline engine of the car.
It was not until the mid-1980s that truck manufacturers in Europe and America applied turbocharging technology to their respective diesel engines. It was also in this year 10 that domestic cars gradually popularized models with turbochargers.
