An automotive turbocharger is a device that uses the exhaust gas flow to spin a turbine to drive a compressor, which can send more air into the engine, making the engine produce more explosive power and better fuel economy. This is because the turbocharger can adjust the intake air volume and pressure according to the working state of the engine, so that the engine is always at the best working point. When the engine needs more power, the turbocharger can provide more air to the engine, making the engine more explosive; when the engine needs to save fuel consumption, the turbocharger can reduce air to the engine, making the engine more powerful Better fuel economy.
