Rating guidelines
PRIME POWER rating corresponds to ISO Standard Power for continuous operation. It is applicable for supplying electrical power at variable load for an unlimited number of hours instead of commercially purchased power. A10 % overload capability for governing purpose is available for this rating.
STAND-BY POWER rating corresponds to ISO Standard Fuel Stop Power. It is applicable for supplying standby electrical generator at variable load in areas with well established electrical networks in the event of normal utility power failure. No overload capability is available for this rating. Average power output over 24 h of operation shall not exceed 70% of emergency stand-by power. Engine operation up to 200 h of operation per year.
1 kW = 1 hp x 1.36
1 hp = 1 kW x 0.7355
Power standards
The engine performance corresponds to ISO 3046, BS 5514 and DIN 6271. The technical data applies to an engine without cooling fan and operating on a fuel with calorific value of 42.7 MJ /kg (18360 BTU/lb) and a density of 0.84 kg/liter (7.01 lb/US gal), also where this involves a deviation from the standards. Power output guaranteed within 0 to +2% at rated ambient conditions at delivery. Ratings are based on ISO 8528. Engine speed governing in accordance with ISO 8528-5.
