A car turbocharger is a magical device that allows your engine to breathe more air, which can make your car have more power and lower fuel consumption. This is because the turbocharger can use the high-temperature and high-pressure gas in the exhaust pipe to drive a turbine, which is connected to a compressor through a shaft. The compressor can compress the air in the atmosphere and send it to the cylinder of the engine, increasing The intake air volume and the density of the mixture are increased, thereby improving the combustion efficiency and output power of the engine. At the same time, since the turbocharger can make the engine achieve higher torque at a lower speed, it can reduce the fuel consumption and emissions of the engine.
