Engine Performance (Diesel Engines)

All rating conditions are based on SAE J1995,

inlet air standard conditions of 99 kPa

(29.31 in.Hg) dry barometer and 25C (77F)

temperature. Performance measured using a

standard fuel with fuel gravity of 35 API

having a lower heating value of 42,780 kJ/kg

(18,390 Btu/lb) when used at 29C (84.2F) with

a density of 838.9 g/L (7.009 lb/gal).

HEP Prime Power Definition and Guidelines:

All ratings shown and thermal ratings are

subject to manufacturing tolerances of plus or

minus 3 percent.

Typical Load Factor is the sum of the loads a

generator set experiences while it is running

under load divided by the number of hours

it operates under those loads. Extended

idling time and the time when the generator

set is not operating does not enter into the

calculation for load factor.

Average power output = 70% of prime power

rating.

Load = Varying.

Typical Hours/Year = Unlimited.

Typical Peak Demand = 100% of prime

rated ekW with 10% overload capability for

emergency use for a maximum of 1 hour in 12.

Overload operation cannot exceed 25 hours

per year.
