Maintenance
Cleaning the compressor during
operation
Wet cleaning with orifice plate on filter silencer (XC2)
Operating state prerequisites for wet cleaning XC2
In the case of V-engines with several turbochargers on each engine, it is
recommended that both turbochargers are cleaned in parallel. This clean-
ing process is faster and the risk of turbocharger surging is reduced.
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 increased.
No personnel is allowed to be present in the vicinity of the turbo-
charger during compressor cleaning.
Compressor cleaning must be activated from the engine control pan-
el.
Compressor wet cleaning operation with XC2
Trigger water injection according to the specifications of the en-
ginebuilder.
The specified water pressure upstream of the connection to the turbo-
charger must be maintained.
Operate engine for at least five additional minutes after cleaning.
The cleaning process can be repeated up to two times.
How successful the cleaning was, can be seen from the charging pres-
sure or the exhaust gas temperature.
If the cleaning is still unsuccessful after three cleaning processes and the
engine values are unsatisfactory, it is recommended to have the turbo-
charger checked and cleaned by an ABB Turbocharging Service Station.
