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) 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 o Engine Type 4-Cycle, V-type, 8-Cylinder, Turbo charged & intercooled (air to air) 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 14.618 liters 15 : 1 Counter clockwise viewed from Flywheel 1-5-7-2-6-3-4-8 23°±1 ° BTDC @ 1800 rpm, 18°±1 ° BTDC @ 1500 rpm, 1155 kg (with fan) 1,274 x 1,138 x 1,207 mm SAE NO.1M Clutch NO.14M 160 o Maximum Bending Moment at Rear Face to Block 1,325 N.m o Maximum Back Pressure 5.9 kPa o Maximum Intake Air Restriction .
