SCANIA POWER GENERATION engines DC09 071A. 226-251 kW (250-275 kVA) EU Stage IIIA The engines for power generation from Scania are based on a robust design with a strength optimised cylinder block containing wet cylinder liners that can easily be exchanged. Individual cylinder heads with 4 valves per cylinder promotes repairability and fuel economy. The engine is equipped with a Scania developed Engine Management System, EMS, in order to ensure the control of all aspects related to engine performance. The injection system is based on electronically controlled unit injectors that gives low exhaust emissions with good fuel economy and a high torque. For further reduction of NOx emissions the engines are also equipped with an exhaust gas recirculation, EGR, system developed by Scania. The engine can be fitted with many accessories such as air cleaners, radiators and PTOs in order to suit a variety of installations. Engine speed (rpm) 1500 rpm (50 Hz) PRP 1800 rpm (60 Hz) Standard equipment • Scania Engine Management System, EMS • Unit injectors, PDE • Turbocharger • Fuel filter and extra pre-filter with water separator • Oil filter, full flow • Centrifugal oil cleaner • Oil cooler, integrated in block • Oil filler, in valve cover • Deep front oil sump • Oil dipstick, in block • Magnetic drain plug for oil draining • Starter, 1-pole 6.0 kW • Alternator, 1-pole 100A • Flywheel, SAE 14 • Silumin flywheel housing, SAE 1 flange • Front-mounted engine brackets • EGR system • Open crankcase ventilation • Operator’s manual Optional equipment • Cooling package • Fan • Side-mounted PTO • Exhaust connections • Instrument panel • Engine heater • Stiff rubber engine suspension • Air cleaner • Closed crankcase ventilation • Studs in flywheel housing • Low coolant level reaction • Fine tune potentiometer • Ramp start delay • Ramp up rate PRP Gross power (kW) 226 251 Gross power (kVA) 250 275 Spec fuel consumption.
