5.2 Cleaning the compressor during operation

General

The contamination of the compressor stage (compressor wheel, wall in-
sert and diffuser) depends on the degree of purity of the air that is
drawn in.

Deposits can form in the flow channels if salt, oil mist, exhaust gas or
dust are sucked in with the air.

Consequences of contamination:

¡

Impaired compressor efficiency

¡

Higher exhaust gas temperatures

¡

Increased fuel consumption

¡

Increased rotor unbalance

Periodic cleaning of the compressor during operation prevents or delays
any major increase in contamination. It does not, however, replace the
regular service work, during which the turbocharger is completely dis-
mantled and the compressor is cleaned mechanically.

NOTICE

If the coating of dirt is very thick and hard, the compressor can only be
cleaned manually when disassembled. This cleaning must be carried out
by an ABB Turbocharging Service Station.

Cleaning interval

The interval between periodic cleaning is very dependent on the operat-
ing conditions. In general, cleaning should be carried out every 25 ... 100
operating hours.

Should the specified cleaning intervals prove incompatible with engine
operation, please contact ABB Turbocharging.
