Engine Control Components: Turbocharger

The turbocharger assembly is an exhaust driven centrifugal compressor. Expanding exhaust gases drive the turbine shaft assembly to speeds over 100, 000 RPM. The turbocharger increases the power output of an engine by increasing the mass of air entering the engine.

Three types of turbocharger are currently being used.

The first type of turbocharger has an integrated wastegate and a remote bypass valve.
