Repair it or contact the manufac-
turer
Poorly adjusted injection
system
Correct it
Engine performance higher
than expected
Check engine performance
Turbocharger Manometer display wrong
Replace the manometer
Fouling of the compressor due to the feeding in of ventilation gases
Reduced compressor performance/efficiency, hence engine performance
losses
Possible causes
Remedy
Turbocharger Heavy fouling of the com-
pressor components
Clean compressor
Optimize oil separation
Increased vibrations, com-
pressor blade damage
Correct the feed of ventilation
gases according to instructions
of enginebuilder.
Reduced fatigue strength of the compressor wheel, compressor blade
failure.
Possible causes
Remedy
Turbocharger Material of compressor
wheel corroded
Check the fuel and its corrosive
components, and change fuel if
necessary.
