Ratings & Other Information



Continuous is the horsepower and speed capability of the engine which can be used without interruption or load cycling.

Performance at SAE standard conditions of 29.38 in (746 mm) Hg. and 85°F (30°C)-SAE J816. Metric conditions are 736 mm (28.97 in) Hg. and 20°C (68°F)-DIN 6270.

Fuel Consumption is based on fuel oil having a HHV of 19,590 btu/lb. (45,570 kJ/kg) and weighing 7.076 Lb. per U.S. gal (848 gm per litre).

Other Ratings Published intermittent and continuous ratings are a general guide for world-wide use over a broad application range. Other ratings, yielding higher performance and economic return, are available to meet the requirements of particular applications.

Miscellaneous Information



Maximum is the horsepower capability of the engine that can be demonstrated within 5% at the factory.

Shaft Horsepower is the output capability the engine equipped with air cleaner, fuel, lube oil jacket water pump and marine gear i.e. net output.

Intermittent is the horsepower and speed capa bility in applications having variable speed and/o load requirements.
