Charge air pressure too high
Engine performance and engine speed unchanged, suction condition normal
Possible causes Remedy
Turbocharger Manometer display not correct Replace manometer
Increased speed due to contamination of
nozzle ring
Clean (see chapter Periodic maintenance
work →30) or contact an ABB Turbochar-
ging Service Station
Engine Malfunction in the injection system Repair or contact manufacturer
Injection mistimed Set correctly
Engine performance higher than indic-
ated
Check engine performance
Table21: Malfunctions during operation – Charge air pressure too high
Reduced compressor performance/efficiency and therefore engine performance
losses
CAUTION
Compressor damage
A severely contaminated or corroded compressor wheel can reduce the com-
pressor wheel’s fatigue endurance limit and result in the turbocharger being
damaged.
u Rectify malfunction in accordance with the following table.
Possible causes Remedy
Turbocharger Compressor components severely con-
taminated by the ventilation gases that
have been fed in
Clean (see chapter Periodic maintenance
work →30)
Optimize oil separation
Increased blade vibration, compressor
blade damage due to the ventilation
gases that have been fed in
Correct the feed of ventilation gases ac-
cording to instructions of enginebuilder.
Material of the compressor wheel cor-
roded due to the feeding in of ventilation
gases containing corrosive components
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 (see chapter Periodic maintenance
work →30)
