What's the difference between turbocharging and twin turbocharging?

The difference between turbocharging and double turbocharging;

1. Double turbocharging mainly adopts the supercharging system of two independent turbochargers. When the two turbochargers of the engine work together, the intake efficiency is greatly improved, and the supercharging effect and dynamic performance are also obviously improved, mainly to improve the turbine delay mentioned above.

However, the twin-turbo engine can not completely eliminate the turbine delay phenomenon. After all, the inertia of turbocharger impeller still exists. In practical applications, twin-turbo engines are usually installed on large-displacement inline 6-cylinder or V-type engines.

2. Single turbocharging is to pre-compress the gas before entering the cylinder by using a special compressor to improve the sealing degree of the gas entering the cylinder and reduce the volume of the gas. Therefore, the gas mass per unit volume is obviously increased, and more fuel can be injected into the limited cylinder volume for combustion, thus improving the engine power.
