6 Periodic maintenance
6.4.4 Wet cleaning with direct water supply
Prerequisites
On V-engines with several turbochargers per engine, parallel cleaning of both turbochargers is
recommended. This cleaning process is faster and reduces the risk of surging of the turbocharger.
Increased stress on material
During cleaning of the compressor at an engine load of 85 to 100 %, the
stress on the material of the compressor-end turbocharger parts can be
WARNING
increased.
No personnel is allowed to be present in the vicinity of the turbocharger

during compressor cleaning.
Compressor cleaning must be activated from the engine control panel.

Wet cleaning operations for compressor with direct water supply
Trigger water injection according to the specifications of the enginebuilder.
