15.3.3 Water cleaning of compressor
The compressor can be cleaned by injecting water during opera-
tion. The method is efficient provided that contamination is not
too far advanced. If the deposit is very heavy and hard, the
compressor must be dismantled and cleaned mechanically.
The injected water does not act as a solvent, the cleaning effect
is achieved by the physical impact of the drops on the deposit. It
is therefore advisable to use clean water containing no additivities
either in the form of solvents or softening agents, which could be
precipitated in the compressor and form deposits.
Regular cleaning of the compressor prevents or delays the
formation of deposit, but it does not eliminate the need of normal
overhauls, for which the turbocharger has to be dismantled.
The water must be injected while the engine is running and at
the highest possible load, i.e. at a high compressor speed.
Note!
Clean the compressor (air side) of the turbocharger at as high
load as possible (at least 75% load).
Cleaning should take place regularly according to maintenance
schedule, see chapter 04. Depending on the results obtained, the
interval between two washings may be increased or reduced.
15.3.4 Compressor cleaning procedure
1 Record charge air pressure,
cylinder exhaust gas tem-
peratures, charger speed. These for later use to evaluate the
efficiency of the cleaning.
2 Open the valve (2),
see Fig 15-3.
3 Connect the water hose.
4 Use same adjustment as
for turbine side, i.e. wash the
turbine side first and lock the valve (5) by using the counter
nut, see Fig 15-3.
