RATING definitions and CONDITIONS
Engine Performance is corrected to inlet air standard
conditions of 99 kPa (29.31 in. Hg) dry barometer and
25°C (77°F) temperature. These values correspond to
the standard atmospheric pressure and temperature as
shown in SAE J1995.
The corrected performance values shown for Cat engines
will approximate the values obtained when the observed
performance data is corrected to SAE J1995, ISO 3046-2,
ISO 8665, ISO 2288, ISO 9249, ISO 1585, EEC 80/1269,
and DIN 70020 standard reference conditions.
Performance measured using a standard fuel with fuel
gravity of 35 degrees API having a lower heating value of
42,780 kJ/kg (18,390 BTU/lb) when used at 29°C (84.2°F)
where the density is 838.9 g/L (7.001 lb/U.S. gal).
IND-E
For service where maximum power is required for a
short time for initial starting or sudden overload. For
emergency service where standard power is unavailable
(time at full load not to exceed 5% of the duty cycle).
