2.3.1 Operating at low and load and idling with S.C.R. (Warstila
NOR)
When engine is coupled with a Selective Catalytic Reduction system, the following
recommendations apply:
Absolute idling (declutched main engine, disconnected generator)
●
Maximum 10 minutes if the engine is to be stopped after the idling. 3-5 minutes idling

Selective Catalytic Reduction system resetting operation
In case engine has to be run for prolonged time at low loads, Selective Catalytic Reduction
system resetting operation must be performed at the intervals indicated, as follows:
Engine must be loaded to minimum 70 % of the rated output for 1 hour or to minumum 50 %
of the rated output for 2 hours or alternatively engine must be loaded to minumum 25 % of
the rated output for 4 hours.
SCR resetting operation can be split into multiple operational events in case extended high
load operation is not feasible. As an example, one 1 hour engine operation at 70 % of the
