RATING DEFINITIONS AND CONDITIONS

A Rating (Unrestricted Continuous)Typical applications: For vessels operating atrated load and rated speed up to 100% of the timewithout interruption or load cycling (80% to 100%load factor). Typical applications could include butare not limited to vessels such as freighters,tugboats, bottom drag trawlers, or deep rivertugboats. Typical operation ranges from 5000 to8000 hours per year.

Power at declared engine speed is in accordancewith ISO3046-1:2002E. Caterpillar maintainsISO9001:1994/QS-9000 approved engine testfacilities to assure accurate calibration of testequipment. Electronically controlled engines are setat the factory at the advertised power corrected tostandard ambient conditions. The published fuelconsumption rates are in accordance with ISO3046.

Fuel rates are based on fuel oil of 35 API [16C(60F)] gravity having an LHV of 42 780 kJ/kg(18,390 Btu/lb) when used at 29C (85F) andweighing 838.9 g/L (7.001 lb/U.S. gal). Additionalratings may be available for specific customerrequirements. Consult your Caterpillarrepresentative for additional information.

Performance No.: DM9574-00 2008 CaterpillarU.S. Sourced All rights reserved.LEHM7331-01 (1-08) Materials and specifications are subject to change without notice.

The International System of Units (SI) is used in this publication.

Performance data is calculated in accordance with tolerances and conditions stated in this specification sheet and is only intended for purposes ofcomparison with other manufacturers engines. Actual engine performance may vary according to the particular application of the engine and operatingconditions beyond Caterpillars control.

Power produced at the flywheel will be within standard tolerances up to 49C (120F) combustion air temperature measured at the air cleaner inlet, and fueltemperature up to 52C (125F) measured at the fuel filter base. Power rated in accordance with NMMA procedure as crankshaft power. Reduce crankshaftpower by 3% for propeller shaft power.
