Power classes
Scania supplies engines in five different power
classes:
ICFN, Continuous service: Intended for contin-
uous use and an unlimited number of operational
hours per year at a total load factor of 100%.
Stage V engines designed for continuous use
generate a high temperature at low rotational
speed. At a rotational speed of up to 1,200 rpm,
the engine must therefore only be run with a
100% load factor for a limited time of three min-
utes. The engine then needs to be cooled for at
least 12 minutes with a load factor of up to 85%.
IFN, Intermittent service: Intended for periodic
use, where the rated power is available for one
hour per three-hour period. The total load factor
must not exceed 80% of the rated power. Unlim-
ited number of operational hours per year.
PRP, Prime power: Intended for continuous use
and an unlimited number of operational hours
with varying loads. The average load factor must
not exceed 70% of the rated power in a 24-hour
period. Accumulated overload 110% for one
hour per 12-hour period. This power class ap-
plies to single-speed engines.
COP, Continuous power: Intended for continu-
al use with a non-varying load and an unlimited
number of operational hours.
ESP, Emergency standby power: Intended for
use with varying loads for a maximum of 200
hours per year. Cannot be overloaded. The aver-
age load factor must not exceed 70% of the rated
power in a 24-hour period. ESP engines are in-
tended as back-up power supplies in the efficient
electrical networks in Europe, North and South
America, Australia, New Zealand, Japan and
Taiwan. In other areas, PRP is recommended for
back-up power supply.
The engine serial numbers and power classes for
the engines that are used in this installation
should be listed below: You can find the power
class of your engine in the engine type data sheet
on the Scania website, www.scania.com.
