Turbocharger is the use of engine exhaust gas inertia impulse to promote the turbine chamber turbine, turbine and drive the coaxial impeller, impeller pressure from the air filter pipeline to send the air, so that it is pressurized into the cylinder. When the engine speed increases, the exhaust gas discharge rate and the turbine speed is also synchronized to increase, the impeller will compress more air into the cylinder, the air pressure and density increases can burn more fuel, accordingly increase the amount of fuel and adjust the speed of the engine, you can increase the output power of the engine.
