Variable Geometry Turbocharger Turbochargers works on the simple principle of increasing the intake air density by compression. Being able to fill more air into the combustion chamber will allow more fuel to be added to produce more power. However the operation of the turbocharger relies solely on the exhaust gas velocity to drive the compressor. Thus the compressor will be at optimum operation range when the engine is under heavy load. When the throttle is opened‚ it will take a certain period
