Gross power guaranteed within + or - 5% at SAE J1995
and ISO 3046 conditions:

77 °F (25 °C) air inlet temperature
29.31 in.Hg (99 kPa) barometer
104 °F (40 °C) fuel inlet temperature
0.853 fuel specific gravity @ 60 °F (15.5 °C)

Conversion factors:

Power:  kW = hp x 0.746
Fuel:  1 gal = 7.1 lb,  1 L = 0.85 kg
Torque:  N•m = lb-ft x 1.356

All values are from currently available data and are subject
to change without notice.

STANDARD CONDITIONS

All OEM Gen Set Engine Applications must be pre-
screened for torsional vibration compatibility with the
respective alternator end hardware.

OEM Engine Application Engineering will perform this
computer-based analysis work upon request.
