RATINGS DEFINITION S AND CONDITION S Ratings are based on SAE J1349 standard condi tio ns of 29.61 in Hg (100 kPa) and 77°F (25°C). These ratings also apply at ISO3046/1, DIN6271, and BS5514 standard con dit ion s of 29.61 in Hg (100 kPa) and 81°F (27°C); and API 7B-11C standard condi tio ns of 29.38 in Hg (99 kPa) and 85°F (29°C) also apply. Ratings are based on dr y natural gas having a low heat value of 905 btu/ft 3 (35.22 MJ /m 3). Variations in altitude, temp erature, and g as composition from standard conditions may require a reduction in engine horsepower.
Materials and specifications are subject to change without notice. LEHX7576
Turbocharged-aftercooled ratings apply to 4000 ft (1525 m) and 77°F (25°C). For applications wh ich exceed these limit s consult your Caterpillar dealer. Standby — Out pu t av ail abl e w it h v ary in g l oad for the duration of the interruption of the norm al source power. Fuel stop pow er in accordance with ISO3046/1, AS2789, DIN6271, and BS5514. Addit ional ratings m ay be available for specific customer requir ements. Consult yo ur Caterpillar r epresentative for details. The International System of Units (SI) is used in this publication.
