Engine Operation
Power Range
Line 5, Line 1 and Line 9 form the curve for the engine’s operation power range
limit, as defined by Formula 2-5. Each component is governed by different coef-
ficients (see Table 2-1).
Table 2-1 Line 5 coefficients
Formula 2-5
where:
P ............... = selected engine power [kW]
P
CMCR
....... = CMCR engine power [kW]
n ............... = selected engine speed [rpm]

CMCR
....... = CMCR engine speed [rpm]
C2/C1/C0 .. = coefficients / constants
The area formed by Lines 1, 3, 5 and 9 is the range within which the engine
should be operated.
The area limited by Line 7, Line 9 and Line 3 is recommended for continuous op-
eration.
The area between Line 7 and Line 5 is reserved for acceleration, shallow water
and normal operational flexibility. If a PTO is installed, then the operating char-
acteristics of the engine will differ (see section 2.6,  2-10 for further details re-
garding PTO characteristics).
