Charge air pressure too high
Engine performance and engine speed unchanged, suction condition normal
Possible causes
Remedy
Engine
Malfunction in the injection system
Repair or contact manufacturer
Injection mistimed
Set correctly
Engine performance higher than indicated Check engine performance
Turbocharger Manometer display not correct
Replace manometer
Increased speed due to contamination of
nozzle ring
Clean (see chapter Periodic maintenance
45]) or contact an ABB Turbo-
charging Service Station
Table 24: Malfunctions during operation – Charge air pressure too high
Reduced compressor performance/efficiency, hence engine performance losses
CAUTION
Compressor damage
A severely contaminated or corroded compressor wheel can reduce the
compressor wheel’s fatigue endurance limit and result in the turbocharger
being damaged.
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
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 corrod-
ed due to the feeding in of ventilation gas-
es containing corrosive components
Correct the feed of ventilation gases ac-
cording to instructions of enginebuilder.
Material of the compressor wheel corrod-
ed due to intake air containing exhaust
gases or salt
Prevent exhaust gas leakages in the en-
gine space
Clean (see chapter Periodic maintenance
