Gross Engine Power Output - BHP
CONVERSIONS:
(Litres = U.S. Gal x 3.785)
(kWm = BHP x 0.746)
(U.S. Gal = Litres x 0.2642)
(BHP = kWm x 1.34)
Data shown above represent gross engine performance capabilities obtained and corrected in accordance with ISO-3046 conditions of 100 kPa (29.53 in Hg)
barometric pressure [110 m (361 ft) altitude], 25 °C (77 °F) air inlet temperature, and relative humidity of 30% with No. 2 diesel or a fuel corresponding to ASTM D2.
See reverse side for application rating guidelines.
The fuel consumption data is based on No. 2 diesel fuel weight at 0.85 kg/litre (7.1 lbs/U.S. gal).
Power output curves are based on the engine operating with fuel system, water pump and lubricating oil pump; not included are battery charging alternator, fan,
optional equipment and driven components.

POWER RATING APPLICATION GUIDELINES
FOR
GENERATOR DRIVE ENGINES
These guidelines have been formulated to ensure proper application of generator drive engines
in A.C. generator set installations. Generator drive engines are not designed for and shall not be
used in variable speed D.C. generator set applications.
STANDBY POWER RATING is applicable
for supplying emergency power for the
duration of the utility power outage. No
overload capability is available for this
rating. Under no condition is an engine
allowed to operate in parallel with the
public utility at the Standby Power rating.
This rating should be applied where
reliable utility power is available. A
standby rated engine should be
sized for a maximum of an 80%
average load factor and 200 hours
of operation per year. This includes
less than 25 hours per year at the
Standby Power rating. Standby
ratings should never be applied
except in true emergency power
outages. Negotiated power outages
contracted with a utility company
are not considered an emergency.
CONTINUOUS POWER RATING is applicable
for supplying utility power at a constant
100% load for an unlimited number of hours
per year. No overload capability is available
for this rating.
PRIME POWER RATING is applicable for supplying electric power in lieu of commercially
purchased power. Prime Power applications
must be in the form of one of the following two
categories:
UNLIMITED TIME RUNNING PRIME POWER
Prime Power is available for an unlimited number of
hours per year in a variable load application. Variable
load should not exceed a 70% average of the Prime
Power rating during any operating period of 250
hours.
The total operating time at 100% Prime Power shall
not exceed 500 hours per year.
A 10% overload capability is available for a period of
1 hour within a 12 hour period of operation. Total
operating time at the 10% overload power shall not
exceed 25 hours per year.
LIMITED TIME RUNNING PRIME POWER
Prime Power is available for a limited number of
hours in a non-variable load application. It is intended
for use in situations where power outages are contracted, such as in utility power curtailment. Engines
may be operated in parallel to the public utility up to
750 hours per year at power levels never to exceed
the Prime Power rating. The customer should be
aware, however, that the life of any engine will be
reduced by this constant high load operation. Any
operation exceeding 750 hours per year at the Prime
Power rating should use the Continuous Power
rating.
Reference Standards:
BS-5514 and DIN-6271 standards are based on ISO-3046.
Operation At Elevated Temperature And Altitude:
The engine may be operated at:
1800 RPM up to 5,000 ft (1525 m) and 104 oF (40 oC) without
power deration.
1500 RPM up to 5,000 ft (1525 m) and 104 oF (40 oC) without
power deration.
For sustained operation above these conditions, derate by 4% per 1,000 ft
(300 m), and 1% per 10 oF (2% per 11 oC).
