Contamination of the compressor
Reduced compressor performance/efficiency, hence engine performance losses
Possible causes
Remedy
Low-pressure or
high-pressure
stage
Heavy contamination of the compres-
sor components due to the feeding in
of ventilation gases
Clean the compressor
Optimize oil separation
Increased vibrations, compressor blade
damage due to the feeding in of venti-
lation gases
Correct the feed of ventilation gases ac-
cording to instructions of enginebuilder.
Table 27: Malfunctions during operation – Compressor 1 contamination
Reduced fatigue strength of the compressor wheel, compressor blade breakage.
Possible causes
Remedy
Low-pressure or
high-pressure
stage
Material of the compressor wheel cor-
roded due to the feeding in of ventila-
tion gases containing corrosive com-
ponents
Correct the feed of ventilation gases ac-
cording to instructions of enginebuilder.
Material of the compressor wheel cor-
roded due to intake air containing ex-
haust gases or salt
Prevent exhaust gas leakages in the en-
gine space
Clean the compressor
