The exhaust turbocharger utilizes the high-temperature exhaust gas from the engine, which is between 700 and 900 degrees Celsius, to drive the turbine in the turbine. The turbine shaft drives the impeller in the compressor to rotate at high speed, compressing air in a centrifugal manner, and increasing the intake density of the engine to 2-3 atmospheres. Thus, we can inject more fuel into the engine to increase its own power.
The exhaust turbocharger is composed of a turbine driven by exhaust gas, a compressor that compresses fresh air, an intermediate that serves as a bearing support in the middle, and a bypass valve control mechanism.
