How the Volkswagen TSI Engine Works

Model: Volkswagen Volkswagen Various
Part: Engine

Video tutorial

This video shows an animation detailing how a Volkswagen TSI engine works: in this engine, petrol is injected directly into the combustion chamber under high pressure and mixed with air via a turbocharger, where the spark plug ignites the combustion.

TSI also stands for downsizing, which means high performance and high torque.

Additionally, it is economical: with ACT technology, two of the four cylinders can be deactivated depending on power demand, reducing fuel consumption and consequently harmful emissions.
