8 Troubleshooting / 8.2 Malfunctions during operation
Contamination of the compressor
Reduced compressor performance/efficiency and therefore engine performance losses
Possible causes
Low-pressure
Heavy contamination of the com-
or
pressor components due to the in-
high-pressure
flux of ventilation gases
stage
Increased vibration, compressor
blade damage due to the influx of
ventilation gases
Table 34: Malfunctions during operation – Compressor 1 contamination
Reduced fatigue strength of the compressor wheel, compressor blade breakage.
Possible causes
Low-pressure
Material of the compressor wheel
or
corroded due to the influx of ventila-
high-pressure
tion gases containing corrosive com-
stage
ponents
Material of the compressor wheel
corroded due to intake air containing
exhaust gases or salt
