Points to remember when
cleaning
¡ When cleaning, water must be drained from the gas outlet casing via
the drain pipe (8).
¡ The exhaust gas temperature following the turbocharger sinks dur-
ing cleaning (by 60...180°C).
¡ Water might (but need not necessarily) flow out of the drain pipe, de-
pending on the engine load. This flow might not start for 2...3
minutes, or it might not occur at all.
¡ If the drainage of the gas outlet casing is omitted, the turbocharger
speed and/or the gas inlet temperature must be monitored during
the cleaning process. If the load is too low, water can collect in the
gas outlet casing. Signs of this are a sudden significant drop in tur-
bocharger speed or a very strong increase in the gas inlet temperat-
ure. In such cases, cleaning must be stopped and the cleaning cycle
repeated from the beginning using a lower water pressure or higher
engine load.
