General
The charging compresses the intake fresh air and increases the cylinder charge level. The engine output increases.
Function
The exhaust gases reach the turbine wheel via the intake on the exhaust gas turbocharger's turbine wheel housing.
Via a constriction, thermal energy is converted into kinetic energy and the turbine wheel starts to rotate.
The turbine wheel is on the same shaft as the compressor wheel. The compressor wheel is set in motion by the rotation of the turbine wheel and intakes fresh air.
The fresh air sucked in is compressed in the compressor wheel housing and reaches the engine through an outlet via the charge air cooler.
