The Citroen Turbocharger is a mechanical device that increases the pressure of air entering the engine to create more power. It is a type of forced induction system, which compresses the air flowing into the engine, allowing it to burn more fuel and do more work, thus increasing the power output. This technology is commonly used in Citroen car models to improve performance and efficiency. The turbocharger is made up of two main components: the turbine and the compressor. The turbine is driven by the exhaust gas from the engine, which in turn drives the compressor, compressing the intake air and supplying it to the engine under pressure. This results in a significant boost in engine power.
