Turbochargers are actually air compressors that increase the amount of intake air by compressing the air. The turbine drives a coaxial impeller by utilizing the inertial impulse of exhaust gas discharged by the engine, and the impeller presses and sends air sent by an air filter pipeline to be pressurized into a cylinder. When the rotation speed of the engine increases, the exhaust gas discharge speed and the turbine rotation speed also synchronously increase, the impeller compresses more air to enter the cylinder, more fuel can be combusted by increasing the pressure and the density of the air, and the output power of the engine can be increased by correspondingly increasing the fuel quantity and adjusting the rotation speed of the engine. Racing sports cars are typically equipped with a turbocharger on the engine to cause the car to burst more power. The engine generates power by combusting fuel in the cylinder, the input fuel quantity is limited by the air quantity sucked into the cylinder, the generated power is also limited, and if the running performance of the engine is in an optimal state, the output power is increased, the fuel quantity can be increased only by compressing more air into the cylinder, and the combustion function is improved. Turbochargers are the only mechanical devices that enable the engine to increase its output without changing its operating efficiency.
