First, the exhaust gas from the engine pushes the turbine impeller at the exhaust end of the turbine to rotate. Therefore, it can simultaneously drive the compressor impeller on the other side connected with it to rotate.
Second, the compressor impeller forcibly sucks air from the air inlet, and after being compressed by the rotation of the blades, it enters the compression channel with smaller and smaller diameter for secondary compression, and these compressed air are injected into the cylinder for combustion.
Thirdly, some engines are equipped with intercoolers to reduce the temperature of compressed air, improve the density and prevent engine knocking.
Fourthly, the compressed (and cooled) air enters the cylinder through the intake pipe to participate in combustion and work.
5. The burnt exhaust gas is discharged from the exhaust pipe and enters the turbine, and then the above-mentioned (1) action is repeated.
It was invented by Swiss engineer Bisch. He applied for 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.
