7 Eliminating malfunctions / 7.2 Malfunctions during operation
Exhaust gas temperature too high
Engine performance and engine speed unchanged
Possible causes
Turbocharger Insufficient air, for example, when
filter silencer is blocked by contam-
ination
Compressor/turbine contaminated
Exhaust gas back pressure too high Clean or repair boiler or exhaust gas si-
Turbine damaged or eroded
Engine Malfunction in the injection system Repair or contact manufacturer
Charge air Cooler contaminated
cooler
Cooling water volume too low
Inlet temperature of cooling water
too high
Insufficient ventilation

Engine performance and engine speed unchanged, suction condition normal
Possible causes
Turbochar- Manometer display not correct
ger
Supply pipe to manometer not sealed Repair leak
Filter silencer contaminated, therefore
pressure drop too high
Compressor end and/or turbine end
contaminated
Compressor/turbine damaged
Exhaust gas back pressure too high
Engine Air receiver not sealed
Gas piping between engine and tur-
bine leaking
Injection mistimed
Valve control misadjusted
Pipes Pipes downstream to the compressor
