What is the pressure of the turbocharger?
The pressure of the supercharger is generally 1.2~2.0. The pressure ratio varies from the intervention to the maximum working condition. The maximum pressure ratio depends on the adjustment of each model when matching.
Superchargers include three forms:
Exhaust gas turbocharger, mechanical turbocharger, electric auxiliary turbocharger. The air is compressed by the supercharger to increase the intake density of the engine, thereby increasing the liter power of the engine.
At the same time, due to the improvement of the mixed combustion regulation of the engine, the combustion efficiency is improved, and the effect of fuel saving and emission reduction can also be achieved. It is an important technological advancement for modern engines.
Precautions:
Because the turbocharger often works at high speed and high temperature, the temperature of the turbocharger exhaust gas turbine end is 700-900℃, and the turbocharger rotor rotates at a high speed of tens of thousands to more than 200,000 revolutions. Therefore, in order to ensure the supercharger The normal work, use should pay attention to:
After the engine is started, especially in winter, it should be allowed to run at idle speed for a period of time, so that the lubricating oil can fully lubricate the bearings before the supercharger rotor runs at high speed. oil seal.
After the engine runs at high speed for a long time, it cannot be turned off immediately. When the engine is working, a part of the oil is supplied to the turbocharger rotor bearing for lubrication and cooling.
