What kind of supercharging does the new LaCrosse use?

[ArcherAnn]

The new LaCrosse uses a 2.0T turbocharger. Introduction to turbochargers: A turbocharger is essentially an air compressor that increases intake air volume by compressing air. It utilizes the inertial momentum of exhaust gases from the engine to drive the turbine in the turbine chamber, which in turn drives the coaxial impeller. The impeller then pressurizes the air delivered through the air filter pipe, forcing it into the cylinders. Structural principle of turbochargers: The exhaust gas turbocharger mainly consists of a pump wheel and turbine, along with some other control components. The pump wheel and turbine are connected by a shaft (called the rotor). The exhaust gases from the engine drive the pump wheel, which then rotates the turbine. The rotating turbine pressurizes the intake system.
