What Does Twin-Turbocharging Mean?

[ThomasLynn]

Twin-turbocharging is one of the turbocharging methods. To address the turbo lag phenomenon in exhaust turbocharging, it involves connecting one large and one small turbocharger in series or two identical turbochargers in parallel. At low engine speeds, even a small amount of exhaust gas can drive the turbocharger to rotate at high speed, generating sufficient intake pressure and reducing the turbo lag effect. The meaning of turbocharging: 1. The main function of turbocharging is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the car more powerful. When an engine is equipped with a turbocharger, its maximum power can increase by 40% or more compared to when it is not equipped with a turbocharger; 2. Turbocharging technology uses a specialized compressor to pre-compress the gas before it enters the cylinder, increasing the density of the gas entering the cylinder and reducing the volume of the gas; 3. The mass of gas per unit volume is greatly increased, allowing more fuel to be injected and burned within the limited cylinder volume, thereby achieving the goal of increasing engine power.
