GEN SET - PACKAGED - DIESEL
TOLERANCES:
AMBIENT AIR CONDITIONS AND FUEL USED WILL AFFECT THESE VALUES.
EACH OF THE VALUES MAY VARY IN ACCORDANCE WITH THE FOLLOWING
TOLERANCES.
ENGINE POWER +/- 3%
EXHAUST STACK TEMPERATURE +/- 8%
GENERATOR POWER +/- 5%
INLET AIR FLOW +/- 5%
INTAKE MANIFOLD PRESSURE - GAGE +/- 10%
EXHAUST FLOW +/- 6%
SPECIFIC FUEL CONSUMPTION +/- 3%
FUEL RATE +/- 5%
HEAT REJECTION +/- 5%
HEAT REJECTION EXHAUST ONLY +/- 10%
CONDITIONS:
ENGINE PERFORMANCE IS CORRECTED TO INLET AIR STANDARD CONDITIONS
OF 99 KPA (29.31 IN HG) AND 25 DEG C (77 DEG F).
THESE VALUES CORRESPOND TO THE STANDARD ATMOSPHERIC PRESSURE AND
TEMPERATURE IN ACCORDANCE WITH SAE J1349. ALSO INCLUDED IS A
CORRECTION TO STANDARD FUEL GRAVITY OF 35 DEGREES API HAVING A
LOWER HEATING VALUE OF 42,780 KJ/KG (18,390 BTU/LB) WHEN USED AT
29 DEG C (84.2 DEG F) WHERE THE DENSITY IS 838.9 G/L (7.002
LB/GAL).
THE CORRECTED PERFORMANCE VALUES SHOWN FOR CATERPILLAR ENGINES WILL
APPROXIMATE THE VALUES OBTAINED WHEN THE OBSERVED PERFORMANCE
DATA IS CORRECTED TO SAE J1349, ISO 3046-2 & 8665 & 2288 & 9249 &
1585, EEC 80/1269 AND DIN70020 STANDARD REFERENCE CONDITIONS.
ENGINES ARE EQUIPPED WITH STANDARD ACCESSORIES; LUBE OIL, FUEL
PUMP AND JACKET WATER PUMP. THE POWER REQUIRED TO DRIVE
AUXILIARIES MUST BE DEDUCTED FROM THE GROSS OUTPUT TO ARRIVE AT THE
NET POWER AVAILABLE FOR THE EXTERNAL (FLYWHEEL) LOAD. TYPICAL
AUXILIARIES INCLUDE COOLING FANS, AIR COMPRESSORS, AND CHARGING
ALTERNATORS.
RATINGS MUST BE REDUCED TO COMPENSATE FOR ALTITUDE AND/OR AMBIENT
TEMPERATURE CONDITIONS ACCORDING TO THE APPLICABLE DATA SHOWN ON
THE PERFORMANCE DATA SET.
GEN SET - PACKAGED - DIESEL
ALTITUDE:
ALTITUDE CAPABILITY - THE RECOMMENDED REDUCED POWER VALUES FOR
SUSTAINED ENGINE OPERATION AT SPECIFIC ALTITUDE LEVELS AND AMBIENT
TEMPERATURES.
COLUMN "N" DATA - THE FLYWHEEL POWER OUTPUT AT NORMAL AMBIENT
TEMPERATURE.
AMBIENT TEMPERATURE - TO BE MEASURED AT THE AIR CLEANER AIR INLET
DURING NORMAL ENGINE OPERATION.
NORMAL TEMPERATURE - THE NORMAL TEMPERATURE AT VARIOUS SPECIFIC
ALTITUDE LEVELS IS FOUND ON TM2001.
THE GENERATOR POWER CURVE TABULAR DATA REPRESENTS THE NET
ELECTRICAL POWER OUTPUT OF THE GENERATOR.
