• These ratings apply at 2,000 rpm when tested under the

specified standard conditions for the specified standard.

• Power rating conditions are based on standard air conditions

of 25° C (77° F) and 99 kPa (29.32 in Hg) dry barometer, used
35° API gravity fuel having an LHV of 42 780 kJ/kg (18,390 Btu/lb)
when used at 30° C (86° F) [ref. a fuel density of 838.9 g/L
(7.001 lb/gal).

• Net power advertised is the power available at the flywheel

when the engine is equipped with fan, air cleaner, muffler
and alternator.

• No derating required up to 3300 m (11,000 ft) altitude.
