Rotor

Together, the shaft, turbine wheel, and impeller make up the rotor. The rotor developed by Bosch Mahle Turbo Systems has a low moment of inertia. This allows the exhaust gas turbocharger to build up boost pressure spontaneously in typical vehicle acceleration phases. Consequently, the engine is highly responsive and can provide a high torque even at low rotational speeds ("low-end torque"). This means that turbo lag, which used to occur in vehicles with turbocharged engines, is now a thing of the past.

Bearing

Bosch Mahle Turbo Systems uses two separate floating bush bearings. The bearing combines low friction with outstanding durability. This is crucial, especially for use in commercial vehicles. In order to meet the increasingly strict emissions requirements, double shaft seal rings are used on the compressor and turbine sides.
