3 Fuel consumption has a tolerance of +5% and is based on fuel of 35 API gravity at 16 C (60 F) having an LHV of 42, 780KJ/KG (18,390 BTU/lb) when used at 29 C (85 F) and weighing g/liter ( lb/US gal). Observed horsepower is certified within 3% of rated horsepower. Cummins has always been a pioneerin product improvement. Thus specifications may change without notice. Consult your local Cummins professional for further DefinitionsRatings are based on ISO 8665 conditions of 100kPa( in Hg) and 25 C (77 F)and 30% relative humidity. Propeller shaft power represents the net power availableafter typical gear losses and is 97% of rated power.

4 Power rated in accordance withIMCI Continuous DutyIntended for continuous use in variable load applications where full power is limited tosix hours out of every twelve hours of operation. Also, reduced power operations mustbe at or below 200 rpm of the maximum rated rpm. This rating is an ISO 3046 fuel stoppower rating and is for applications that operate less than 3,000 hours per DutyIntended for intermittent use in variable load applications where full power is limited totwo hours out of every eight hours of operation. Also, reduced power operations mustbe at or below 200 rpm of the maximum rated rpm.
