What Does a Turbo Charger Do?

A turbocharger is a turbine-driven device that uses forced induction to increase an internal combustion engine’s power output without sacrificing efficiency. Forced induction pushes more air into the combustion chamber, allowing it to fill in a shorter amount of time and thus increasing its volumetric efficiency. Also, the more quickly and efficiently the chamber is filled, the more fuel that can be used and therefore more power can be produced.

How Do Twin Turbo and Biturbo Engines Work?

Both of these engines are twin turbocharged, simply meaning they use two turbochargers instead of one. How the turbochargers are configured is what separates the engines into two types: parallel and sequential turbos.

Twin Turbo: Sequential Twin Turbo Engines

Twin turbo powertrains that use sequential twin turbochargers rely on two differently sized turbochargers that work independently. The smaller turbocharger is used for lower engine speeds, and the larger turbocharger is used for higher engine speeds. At low RPM rates, the smaller turbo will spool until enough pressure has accumulated to activate the second, larger turbo. Sequential turbocharging provides a way to decrease turbo lag—also referred to as slowed throttle response—without compromising boost output and engine power. Sequential turbocharging also provides a lower boost threshold and increased power output at lower engine speeds.

Mercedes-Benz biturbo: Parallel Twin Turbo Engines

Mercedes-Benz biturbo engines utilize two identical turbochargers simultaneously, therefore equally splitting the turbocharging duties. Typically, each turbocharger is assigned to a specific number of cylinders (for example, turbocharger A is assigned to cylinders 1-3 on a V6 engine, and turbocharger B is assigned to cylinders 4-6). This allows them to work together to create boost faster and more efficiently. Despite losing some top end power, this configuration also reduces turbo lag.
