Brief description: Description: Supercharging

Engine exhaust gases pass a turbine rotor and make it rotated. The turbine rotor is connected directly to a compressor wheel on a shaft, which means that they rotate at the same speed. The compressor wheel increases the pressure in the induction system, allowing more air to enter the engine. Thereby, it is possible to burn more fuel and obtain higher torque and power. The engine control unit governs this process by, for example, releasing excess pressure on the exhaust side when necessary.
