DOOSAN INFRACORE GENERATOR ENGINE Gross Engine Output - without Cooling Fan Net Engine Output - with Cooling Fan Ratings Definitions The power ratings of Emergency Standby and Prime are in accordance with ISO 8528. Fuel Stop power in accordance with ISO 3046. Electric power(kWe) should be estimated by considering generator efficiency, cooling fan power loss and power derating due to altitude and ambient temperature. STANDBY POWER RATING is applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. A standby rated engine should be sized for a maximum of an 70% average load factor and 200 hours of operation per year. This includes less than 25 hours per year at the Standby Power rating. PRIME POWER RATING is available for an unlimited of hours per year in variable load application. Variable load should not exceed a 70% average of the Prime Power rating during any operating period of 24 hours. The Total operating time at 100% Prime Power shall not exceed 500 hours per year. A 10% overload capability is available for a period of 1 hour within a 12 hour period of operation. Total operating time at the 10% overload power shall not exceed 25 hours per year. ◎ GENERAL ENGINE DATA ㅇEngine Model ㅇEngine Type 4-Cycle, V-type, 10-Cylinder, Turbo charged & intercooled (air to air) ㅇCompression ratio Counter clockwise viewed from Flywheel ㅇFiring order ㅇInjection timing ㅇDry weight ㅇDimension (LxWxH) ㅇFly wheel housing ㅇFly wheel ㅇNumber of teeth on flywheel ◎ ENGINE MOUNTING ㅇMaximum Bending Moment at Rear Face to Block ◎ EXHAUST SYSTEM ㅇMaximum Back Pressure ◎ AIR INDUCTION SYSTEM ㅇMaximum Intake Air Restriction .
