Comparison of construction supercharger and turbocharger

 

In fact, when it comes to the comparison of construction superchargers and turbochargers, it is not new!

 

The emergence of turbocharging technology has been more than 100 years old, and mechanical supercharging is earlier, but neither of these two technologies was provided for automobiles. The early mechanical supercharging technology was mainly used for mine ventilation and industrial boilers. gas. Turbocharging was the technology used on aircraft in the First World War. Later, these two technologies slowly entered the automobile industry. With the continuous advancement of modern technology, these two centuries-old technologies Red mess.

 

When it comes to turbocharging, naturally aspirated will naturally be mentioned, and two gangs will be formed immediately—self-powder and vortex powder. The structure of natural aspirated is relatively simple. Turbo is equipped with a set of turbo booster on the basis of natural aspirated. The compressor is naturally stronger than self-priming in terms of power. As for the turbo lag problem, with the advancement of modern technology, the lag is no longer obvious.

 

The principle of turbocharging technology is actually very simple. In simple terms, it consists of a supercharger and a turbine, which are connected by a drive shaft. When the vehicle reaches a certain speed, the exhaust gas discharged from the exhaust valve is enough to push the turbine blades. , the entire turbo system is connected to work. The high-temperature exhaust gas drives the turbine blades to rotate, and the blades drive the supercharger to rotate through the drive shaft to compress the air entering the intake pipe. Because the temperature of the compressed air increases, the air needs the intercooler to dissipate heat before entering the engine intake port to burn.

 

The principle of the construction supercharger is also very simple. The air passes through the intake port, and then enters the main intake port of the supercharger after being filtered by the air filter. The rotation of the supercharger rotor compresses the incoming air, and the generated high temperature gas passes through the medium The cooler cools down and then enters the intake port to burn, so the difference between mechanical supercharging and turbocharging is that no matter how fast or slow the vehicle travels, mechanical supercharging participates in the work, and the supercharger blades are constantly rotating. The difference between turbocharging is that when supercharging is driving at low speeds, the torque will be greater than that of turbocharging, but at high speeds, the power performance is relatively weaker than turbocharging, because supercharging also consumes the engine when driving. The power of the supercharger is more suitable for large-displacement engines, and the supercharger is more precise than the turbocharger, and the maintenance cost will be higher.
