What does turbocharging mean?

Turbine for short. If you see Turbo or T at the rear of the car, it means that the engine chosen by the car is a turbocharged engine. Its working principle is to use the inertia impulse of the exhaust gas discharged by the engine to push the turbine in the turbine chamber, and the turbine pulls the coaxial impeller, which drives more air into the intake manifold through high-speed rotation, thus improving the combustion work efficiency of the engine. Who is the inventor of turbocharger? It is generally believed that the Swiss engineer Bisch published 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 turbochargers on some of its models. The 1970s became the turning point of turbocharging, and Porsche 9 1 1 with supercharged engine came out. However, it was SAAB in Sweden that revived the turbocharging technology. Its Saab 99 model introduced in 1977 spread the turbocharger technology more widely, but at that time the turbocharger was only installed on the gasoline engine of the car. This is not T. It was not until the mid-1980s that European and American truck manufacturers applied turbocharging technology to their diesel engines. It was also in this period of 65,438+00 that domestic cars began to popularize turbochargers. 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, the 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 popular 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. On the other hand, it is to improve fuel economy and reduce exhaust emissions. Million car purchase subsidy
