Background
The turbo-charging pushes the turbine in the turbine chamber through the inertia impulse force of the exhaust gas discharged by the engine to drive the coaxial impeller to rotate, and the impeller compresses the sucked air to be charged into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed rise synchronously, and then the impeller compresses more air to enter the cylinder. Due to the fact that the pressure and the density of the air are increased, under the condition that the volume of the cylinder is not changed, more fuel can be combusted, and the output power of the engine is further increased.
The most serious disadvantage of the turbocharger is the turbo lag effect, that is, the inertia of the impeller slowly reacts to the change of the accelerator in sudden time, so that the air intake amount is insufficient in short time, and the engine delays to increase the output power.
