¡
The exhaust gas temperature downstream of the turbocharger drops drastically during
cleaning (typical turbocharger outlet temperatures during cleaning: 60...180°C).
¡
If there is no drainage of the gas outlet casing, 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. Indicators for this are a sudden severe drop in
the turbocharger speed or a very large increase in the gas inlet temperature. In such
cases, the cleaning operations must be stopped and the cleaning cycle restarted with re-
duced water pressure or higher engine load.
