Some customized engines are delivered with water
washing arrangement consisting of a pipe system

way cock and a drain pipe with a drain valve from
the gas outlet, see illustration on work card

The water for washing the turbine, is supplied from
the external fresh water system through a flexible
hose with couplings. The flexible hose must be dis-
connected after water washing.
By activating the maneuvering valve and the regu-
lating valve the water is sprayed into the exhaust
gas pipe before the turbine side of the turbo-
charger. See specific work card for water washing
of turbine side. The water that is not evaporated is
led out through a drain pipe in the exhaust gas out-
let.
