Cleaning the Turbocharger during Operation
1. General
The turbochargers have a system to clean the compressor. It is possible to clean the
compressor while the turbocharger operates. Regular procedures to clean the
compressor prevent or decrease contamination and increase the time between
overhauls.
If the quantity of dirt becomes too much (scavenge air pressure decreases and
exhaust gas temperature increases), the turbocharger must be disassembled and
cleaned in accordance with the instructions given in the turbocharger manual. See
0250−1 Operating Data Sheet for the permitted pressure decrease.
To keep the silencer in a clean and serviceable condition, regular visual checks and
procedures are necessary. Clean the silencer and filter only when the engine is
stopped and in accordance with the instructions given in the applicable turbocharger
manual.
Note: One more filter mat installed on top of the silencer will keep the
contamination on the air side to a minimum, but will cause a loss of
pressure.
If there is an increase in pressure difference np (of 50% compared to the shop test
value at the same engine load), the filter mat is dirty. To clean the filter mat, refer to
the instructions given in the turbocharger manual.
