Turbocharger: Compressor
During operation fine adhesive dust is deposited on the inner air carrying parts of the turbocharger
which can significantly reduce the performance of the compressor. For cleaning the compressor,
refer to the operating instructions for the turbocharger in manual C.
• Daily cleaning of the compressor
• Periodic washing of the turbocharger during heavy fuel operation: refer to A5.05.06.05.00.nn.
Air charge cooler
• Check the permanent drain/separators of the air charge manifold
Note:
Manual correction of the air charge temperature control is only necessary in special cases!
If there is water in the air charge manifold, raise the air charge temperature until
condensation stops.
• Electronic thermostat: Raise the temperature by adjusting the thermostat.
• Thermostat with diaphragm valve: Raise the temperature of the water or reduce the flow in
the low temperature cooling circuit by opening an external bypass.
Attention: This increases thermal engine stress.
• Observe the maximum permissible exhaust temperatures after the turbine.
Refer to Exhaust temperatures after the turbine.
• If the volume of discharged water is not reduced despite the temperature increase, check the
air charge cooler for leakage.
