Operating conditions
The engine can be operated without any restrictions in the ambient condition
range ‘winter’, as permissible by
, up to design conditions. Operation out
-
side these limits is possible, but further measures might need to be taken and the
power output might be limited (see
4.10.4 Outside ambient air temperature,
). For project-specific support please contact WinGD.
Reference conditions
Engine performance data
—
like BSEC, BSEF, tEaT and others
—
are based on
reference conditions. These conditions are specified in ISO standard 15550 (core
standard) and, for marine application, in ISO standard 3046 (satellite standard)
as follows:
