Engine duration
The engine duration is identified by the relevant BE10 and is related to a given Load Factor (L.F.).
Example: BE10 (L.F. - 0.7) = 10.000 h
It shows that 90% of the engines working with a medium load factor of 70% exceed the operation
duration of 10,000 h, without actions needed for the removal of their main components.
Each engine family and each setting have been associated to a BE10 and the relevant “load factor”.The
values result from the use practical tests and the processing of the different data obtained during the
bench tests.
It is possible to foresee the engine duration for a specific setting and “load factor” with a good margin
of approximation, on the basis of the following correlation:
Figure 6 illustrates the function linking the Duration with the Load Factor.
CAUTION
The engine duration is closely linked to the correct and precise performance of the maintenance
actions foreseen by the manufacturer.
