Supercharger function - GF09.50-P-3102-02AM
The compressor (50) is a screw-type compressor which operates according to the positive displacement principle with inner compression.
The air flowing in is led to the suction side opening (A) at the rear of the operating space of the compressor.
Rotation in connection with the geometry of the two helical spindles 1 and 2 (50/1, 50/2) seals off the operating chamber from the outer environment after entry of the intake air. The enclosed air volume is compressed through a reduction in size of the operating chamber between the housing and the two helical spindles.
Further turning of the screw spindles causes compressed air to be pushed out of the opening on the pressure side (B) in the direction of the charge air cooler.
The maximum charge pressure is about 0.8 bar on achieving the engine break way speed.
The compressor is driven directly from the crankshaft over the magnetic clutch on the mechanical charger and a separate poly-V-belt.
The supercharger is actuated via the supercharger magnetic clutch by the ME-SFI [ME] control unit (N3/10).
