DOOSAN INFRACORE GENERATOR ENGINE 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) must be considered cooling fan loss, alternator efficiency, altitude derating 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 80% 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 number 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 withing a 12 hour period of operation. Total operating time at the 10% overload power shall not exceed 25 hours per year. ◎ GENERAL ENGINE DATA o Engine Model o Engine Type o Bore x stroke o Displacement o Compression ratio o Rotation o Firing order o Injection timing o Dry weight o Dimension (LxWxH) o Fly wheel housing o Fly wheel o Number of teeth on flywheel © ENGINE MOUNTING Counter clockwise viewed from Flywheel 1-5-3-6-2-4 16°±1° BTDC 910kg (with Fan) 1,384 x 1,109 x 1,195 mm SAE NO.1M Clutch NO.14M 152 Maximum Bending Moment at Rear Face to Block 1325 N • M Maximum Back Pressure 5.9 kPa Maximum Intake Air Restriction .
